INTRODUCTION
This Steel Grade Selection and Substitution Guide is intended to support optimal selection
of materials when engineering various metal structures and equipment, including those used at
hazardous production facilities, by means of a comparative analysis (GAP analysis) of the
following standards: GOST, GOST R, TU, ASME, ASTM, EN and API. This approach ensures
an objective assessment in determining physical and chemical properties and characteristics of
Russian and foreign steels, which can significantly widen applicability of the technical information
provided.
This Steel Grade Selection and Substitution Guide includes an analysis of requirements of
the Russian and foreign standards for materials in terms of their chemical composition, strength
characteristics, weldability, and application conditions. In addition to conventional steel grades,
emerging grades of cryogenic and high-strength steels the widespread introduction of which will
significantly reduce CAPEX of future facilities are also considered.
This Steel Grade Selection and Substitution Guide contains general and specialized sections.
The general sections contain information on weldability, corrosion resistance, application
temperatures of various materials, steel grade designations, various methods for calculating the
carbon equivalent and limitations on its value. The specialized sections of this Guide specify
requirements for materials intended for welded steel tanks (vessels) and metal structures.
The appendices contain information on the values of the elastic modulus E and the linear
(temperature) expansion factor of steels depending on temperatures, and information about the
range of products produced by Russian metallurgical plants in accordance with the GOST, TU,
ASME and EN standards.
The Useful Links section contains links to web resources of the main Russian manufacturers,
specialized organizations working in the field of materials science and welding, and their
professional associations. By following these links, the user can get information about the range
and quantities of products produced by each manufacturer, requirements for the minimum batch
size, delivery times, and information about regulatory documents required.

Definition and classification by chemical composition and quality classes is regulated in
accordance with GOST R 54384 (EN 10020: 2000) imposing the following requirements:
- For definition of classes by chemical composition: Non-alloy steels, stainless steels and
other alloy steels.
- For classification of steel grades by main quality classes: Non-alloy steels (Non-alloy
high-quality steels and non-alloy special steels), stainless steels, and other alloy steels (Non-alloy
high-quality steels and non-alloy special steels). In accordance with the requirements, the
following is the broadest classification used in the GOST, GOST R and TU standards.
3.1.1
Carbon Steels
Carbon steel is an alloy of iron with carbon (carbon content up to 2%) with impurities of
sulfur and phosphorus. The main components are carbon, manganese (G) and silicon (C). The
19
INTI R.00.1-2021
composition of such steels includes other elements (Cr, Ni, Cu, etc.) with a low content (≤ tenths
and hundredths).
Carbon steel of commercial quality is divided into the following groups:
A – selected by mechanical properties and used mainly when products made of it are
subjected to hot working (welding, forging, etc.) which can change the regulated mechanical
properties (St0, St1, etc.);
B – selected by chemical composition of steel and used for parts subjected to such treatment
in which mechanical properties change and their level, except for the working conditions, is
defined by the chemical composition (BSt0, BSt1, etc.);
C – selected by mechanical properties and chemical composition for parts subjected to
welding (CSt1, CSt2 etc.);
D – with normalization of chemical composition with control of mechanical properties on
heat-treated specimens. The norms of mechanical properties and heat treatment modes shall
comply with those specified in the steel standards;
E – without normalization of mechanical properties and chemical composition but with
normalization of hydraulic test pressure.
Carbon steels of commercial quality are designated by letters “St” followed by a code
number of the steel grade – 0-6, with indication of the deoxidation method (KP – rimmed steel;
PS – semi-killed steel; SP – killed steel). Steel is considered killed if the deoxidation method is
not specified (St0, St1kp, St1ps, St1sp, St2kp, St2ps, St2sp, Stzkp, Stzps, Stzsp, St4kp, St4ps,
St4sp, St5ps, St5sp, St6ps, St6sp, etc.). When the element content in the alloy is about 0.8-1% or
higher, its symbol is indicated in the steel grade code (St3Gps, St3Gsp, St5Gps, etc.).
3.1.2
Structural Non-Alloy High-Quality Steels
Structural non-alloy high-quality steels are designated by a two-number number indicating
the average carbon content of the alloy multiplied by 100. If the element content in the alloy is
about 0.8-1% or higher, its symbol is indicated in the steel grade code. These numbers are followed
by the deoxidation method designation (KP – rimmed steel; PS – semi-killed steel; SP – killed
steel). Steel is considered to be killed if deoxidation method is not specified (08kp, 08, 10kp, 10,
15kp, 15, 20kp, 20, 25, 30, 30G, 35, 40, 40G, 45, 50, 50G, 55, 60, etc.). High-quality steels with
improved properties that are used to manufacture boilers and pressure vessels are designated by
adding letter “K” at the end of the steel grade code (20K, 22K, etc.).
20
INTI R.00.1-2021
In low alloy structural steels, the content of alloying components shall be no more than 5%.
In the steel grade code, alloying components are listed in descending order of their content (e.g.,
chromium-vanadium, chromium- silicon-manganese, chromium-nickel, etc.). Steels are
designated with a two-number number reflecting the average carbon content multiplied by 100,
followed by a letter designation of elements with an indication of their approximate percentage
content in the alloy (if less than about 1%, the number is usually not indicated; if around 1.5-2%,
the number indicated after the element code is 2). This class includes the following steels: 10G2FB,
10G2FBY, 05HGB, 16GS, 08GBY, 17G1S, 09G2S, 09G2FB, 09GBY, 15XM, 12XM, 12GSB,
13GS and others.
3.1.3
Medium- and High-Alloy Steels
Medium-alloy steels that have a content of alloying elements of 5-10% (15X5M; 20HGSA;
25HGSA, etc.) and high-alloy steels with a content of alloying components of more than 10%
(08X13, 12X17, 08X18N10T, 12X18N10T 03H17N14M3, etc.) are designated in the manner
similar to low-alloy steels. The total content of alloying elements in steel shall not exceed 50%; if
this content is higher then the material is called a ferroalloy.
At the end of a designation code of structural spring steels (50XSA; 65C2VA; 70C3A, etc.),
letter “A” can be used to designate the quality of the steel grade. For this type of steel, the content
of sulfur and phosphorus for each of these elements shall not exceed 0.03%. This designation is
also applicable to chromium-nickel vanadium steels such as 20XN4FA, 38XN3MA, etc.
3.1.4
Structural Bearing Steels
Structural bearing steels (ShX4; ShX10; ShX15; ShKX20SG, etc.) are designated in
accordance with the following rules: letter “Sh” (the group of structural bearing steels) followed by
the symbols of the elements with percentage content of chromium, multiplied by 10.
Example: ShX20SG – structural steel, bearing steel, estimated chromium content 2% (the
real chromium content is about 1.4-1.7%), silicon content 1% and manganese content 1%.
3.1.5
Cast Structural Steels
Cast structural steels (15L; 35XML; 40XL, etc.) are designated in accordance with the same
principles as low-alloy structural steels, and their designation codes are composed in accordance
with the following rules: numbers show the average carbon content multiplied by 100, followed
by symbols indicating percentage content of the main alloying elements. The difference is that at
the end of the designation code letter “L” is indicated (meaning the cast structural steel group).
21
INTI R.00.1-2021
3.1.6
Construction Steels
Construction steels are designated in accordance with their strength classes (S235, S245,
S255, S345, S345K, S355, S355, S355-1, S355-K, S355P, S375, S390, S390-1, S440, S550, S590,
etc.) and their designation codes are composed in accordance with the following rules: letter “S”
is the steel for building structures; numbers 235-590 is the minimum value of yield strength in
accordance with GOST 27772 standard (in N/mm2); number 1 is a variant of chemical
composition; letter “K” means corrosion-resistant steel; letter P means increased fire resistance.
Additionally, the following designations are used: letter “T” is heat-strengthened rolled steel
products; letter K is increased corrosion resistance (S345T; S390K, etc.). Additionally, letter “D”
designates an increased content of copper (S345D; S375D, etc.).
3.1.7
Non-Alloy Tool Steels
Non-alloy tool steels are divided into commercial-quality steels (designated by letter “U”
and the number indicating the average carbon content multiplied by 10 – U7; U8; U10, etc.) and
high-quality steels (designated by an additional letter at the end of the code – U8A; U10A; U12A,
etc., or an additional letter “G” indicating higher manganese content – for example, U8GA).
3.1.8
Alloyed Tool Steels
Alloyed tool steels (3X2MNF, 5XNVS, XVSG, 9XVG, 13X, etc.) are designated in
accordance with the following rules: the first number shows the average carbon content multiplied
by 10 (if the grade code begins with letters then the steel contains about 1% of carbon), and further
alpha-numeric codes are designated in accordance with the rules applied to low-alloy steels.
3.1.9
Non-Alloy Electrical Steels (ARMCO)
Non-alloy electrical steel (also known as ARMCO) is technically pure iron (grades 10880,
20880, etc.). These grades of non-alloy electrical steel contain a minimum amount of carbon (less
than 0.04%), so they have a very low electrical resistivity. The first number in their code designates
the type of working (1 – forged or hot-rolled, 2 – calibrated). The second number designates a nonalloy steel with number 0 meaning without specified ageing factor, and number 1 meaning a
normalized aging factor. The third number indicates the steel group by the main normalized
characteristic (8 means the coercive force). The fourth and fifth numbers are the values of the main
normalized characteristic (coercive force in integer units).
3.2 Steel Grades Designation under EN Standards (European Standards)
EN steels and alloys are regulated by the applicable European norms and standards. The
European standards are developed by the European Committee for Standardization and are
generally accepted for the countries of the European Union.
22
INTI R.00.1-2021
The steel designation system is designated in Standard EN 10027 which consists of two
parts. EN 10027-1 regulates grade designations of steels and assignment of alpha-numeric
designations. EN 10027-2 regulates assignment of steel numbers by group.
In accordance with the EN 10027-1 standard, steels are divided into two main groups. Grade
designations of group 1 of steels are composed based on mechanical/physical properties and on
general purpose of the materials. Steel grade designations consist of one or more letters that
indicate purpose of the steel, and numbers that indicate properties of the steel. In addition to letters
and numbers, there may be additional alphabetic symbols that indicate the supply condition of the
material.
Grade designations of group 2 of steels are composed in view of their chemical composition.

percentage of sulfur multiplied by 100;
4
– if the group 1 symbols do not fully describe the steel, the group 2 symbols are added to
them: the chemical symbol of the specified additional elements, such as Cu, together, where
appropriate, with a single number representing a 10-fold average of the specified range of content
of this element;

Designation for the steel product is not specified.
3.2.2.5 Assigning Numeric Designations to Steels
The procedure of assigning serial numbers to steel grades is determined by European
Standard EN 10027 Part 2: serial number of a steel grade is represented as 1.XXXX, where “1”
33
INTI R.00.1-2021
means that this material is steel. In the future, when expanding the accepted numbering system, it
is suggested to use additional numbers to designate other materials (in the German numbering
system of materials, which is a prototype of the European system, the symbol “0” is used, for
example, to designate cast iron, “2” – to designate heat-resistant alloys based on nickel and cobalt,
“3” – to designate non-ferrous metals and alloys). The next two numbers after “1” mean the
number of the steel group, and the last two numbers mean the serial number of the steel in the
group.
By the group number, one can clearly determine which type a particular steel grade belongs
to. Table 3.2.2.5.1 shows the number ranges used for different types of steels. A more detailed
classification can be found in EN 10027 Part 2.

3.3 Designation of Steel Grades under the ASME/ASTM Standards
Within the framework of the U.S. standardization system, steel grades are designated in
accordance with the ASTM (American Society for Testing and Materials) standards which regulate
chemical composition of steels, mechanical, physical and electrical properties of the material, test
methods and a complete list of all requirements for rolled metal products: size, shape and so on.
Local legislation may require the material to meet the ASTM standards to be allowed for use.
Practical applications of materials are described in the ASME (American society of
Mechanical Engineers) standards. The ASME material specifications are based on publications
from the ASTM, AWS, and other recognized national or international standards. The ASME
standards are legally required for construction of various infrastructure facilities such as bridges,
pipelines of hydroelectric power stations and boiler houses.
The ASME standard for boilers and pressure vessels (Boiler and Pressure Vessel Code)
contains the ASME BPVC Section II Part A Technical Specifications for Ferrous Metals section.
The ASME standards have a reference to the ASTM standards. When a steel grade code is
composed in accordance with the ASME standard, letter “S” (SA-333 Grade 6) is added to the
ASTM grade code. Thus, it is indicated that the values of chemical composition and mechanical
characteristics shall comply with the ASME standard.
The ASTM standards, as a rule, define not only chemical composition of a steel grade but
also a complete list of requirements for products made of this steel grade. Both the ASTM’s own
designation system (in this case, chemical composition of steels and their grade code are defined
directly in the standard) and other designation systems, such as the AISI for bars, wires, etc., or
the ACI for castings made of corrosion-resistant steels can be used to designate steel grades
directly and determine their chemical composition.
As a rule, the ASTM standards use the American system of physical units. If the standard
contains a metric system of units, letter “M” is placed after the steel grade number and is marked
with a “/” sign (A-333/A-333M).
Example: ASTM A – 333 Grade 6 steel
Letter “A” means that we are talking about a ferrous metal; next is the sequence number of
the standard material (333), and the steel grade under the standard (6) is specified.
Below are some examples describing the rules of steel grade designations in accordance with
the ASME and ASTM standards (more details on the steel grade code are specified in each
standard respectively):
38
INTI R.00.1-2021
A-516/A-516M-90 Grade 70 – the first part is designated as described above. Then, the “90” means the year of publication of the standard (in practice, not frequently used in designations).
Then, follows the steel grade 70 (“70” defines the minimum instantaneous strength of the steel in
ksi (485 N/mm2). For grade 60 – 415 N/mm2.
Here and further, the first part is designated in accordance with the rules discussed above;
the differences are in designation of the grade.
A-335/A-335M Grade P22; A-213/A-213M Grade T22; A-336/A-336M Grade F22 – the
letters indicate the product type: “P” and “T” mean steel for pipe products; “F” means steal for
forgings.
SA-47/SA-47M Grade 32510 [22010] – the first three numbers indicate the minimum yield
strength (x 100 lb/sq. inch [MPa]); the last two numbers indicate the minimum elongation.
SA-53/SA-53M Type F Grade A – here “F’ indicates that the pipes are produced by
continuous furnace butt welding, “A” defines chemical composition and mechanical
characteristics of the steel. As required by the standard, designations for Type E and Type S and
the steel grade (letter “B”) are also specified. “E” means that the pipes are produced by electric
contact welding; “S” designates seamless pipes; “B” determines chemical composition and
mechanical characteristics of the steel.
SA-106/SA-106M Grade A (Grade B and Grade C) – letters “A”, “B” and “C” determine
chemical composition and mechanical characteristics. The following mechanical properties are
determined: Grade A = 48 ksi, Grade B = 60 ksi, Grade C = 70 ksi.
SA-351/SA-351M Grade CF8M – here the ACI designation system is used as follows: the
first letter “C” means that the steel belongs to the group of corrosion-resistant steels; “8”
determines the maximum carbon content in it (0.08%), “M” means that molybdenum is added to
the steel.
SA-276 Type 304 L – this standard uses the steel grade designation in the AISI-304 l system
where “L” indicates a reduced carbon content.
SA-312/SA-312M Grade TP304 – a combined designation system is used here. Letters “TP”
indicate that the steel is intended for manufacturing of pipes, “304” is the designation of steel in
the AISI system.
The AISI (American Iron and Steel Institute) designation is used to designate alloy and
stainless steel grades and consists of three numbers with addition of letters at the end (from 1 to 3)
39
INTI R.00.1-2021
as an option. The steel series is determined by the first number, and the last two designate the serial
number of the steel in the group.
Example: 300 series (family of chromium-nickel steels);
400 series (ferritic and martensitic steels);
500 series (chromite heat-resistant steels);
600 series (steel grades that do not fall under the above classification)
Many grade designations of steels in accordance with the ASTM standards are specified
individually and for certain grades their own chemical composition is characteristic. Some standards
specify meaning of the symbols included in the grade codes of the steels used.
3.4 Designation of Steel Grades under the API 5L and ISO 3183 Standards
The API 5L and ISO 3183 standards establish requirements for manufacturing of seamless
and welded steel pipes intended for construction of transportation pipelines in the oil and gas
industry, with two levels of requirements for metal products (PSL 1 and PSL 2). Not applicable to
cast pipes.
PSL 1 – pipes with standard level of properties for pipelines.
PSL 2 – additional mandatory requirements for chemical composition, impact resilience and
strength, and additional non-destructive testing.
3.4.1 Pipe Strength Group and Steel Grades
Strength group of PSL 1 pipes is identical to the steel grade and shall correspond to the
numbers given in Table 3.4.1.1. The letter symbol indicates the strength class, while the number
following the letter symbol indicates the minimum yield strength (L – in MPa, X – in ksi). In the
designation of strength groups A and B, there is no indication of the minimum yield strength (with
the exception of A25 and A25P, which indicate the minimum yield strength value in ksi). The “P”
suffix indicates that the phosphorus content range is set for the steel.
Strength group of PSL 2 pipes shall correspond to the numbers given in Table 3.4.1.1 where
the letter symbol indicates the strength class and the number indicates the minimum yield strength
(ksi). The steel grade code additionally contains a suffix (R, N, Q and M) which indicates the
supply condition (Table 3.4.1.2). The letter sign following the suffix indicating the supply
condition indicates the operating conditions (O – marine environment, S – acidic environments).
There is no indication of the minimum yield strength in the designation of the strength group. For
the metal product, the following symbols are added at the end of the designation: S – seamless

3.5 Designation of Steel Grades under the SAE and AISI Standards
For many years, certain grades of carbon and alloy steels have been designated by the AISI
/ SAE four-digit numbering system, which identifies steel grades in accordance with their standard
chemical composition.
Because the American Iron and Steel Institute (AISI) does not develop material
specifications, the link between the AISI designation and the class designations has been
discontinued. Since 1995, the four-digit steel grade designations used in the Iron and Steel Society
(ISS) Strip Steel Manual have been referred to exclusively as SAE designations.
The SAE system uses a basic four-digit system to indicate the chemical composition of
carbon and alloy steels. Throughout the system, the last two digits indicate the carbon content in
hundredths of a percent. Carbon steel grades are designated as 10XX. For example, a carbon steel
containing 0.45% of carbon is designated as 1045 in this system.
Resulfurized carbon steels are designated in the 11XX series, re-sulfurized and rephosphorized carbon steels are designated in the 12XX series, and steels with a manganese content
of 0.9-1.5% but without alloying elements are designated in the 15XX series. Content ranges for
manganese and silicon and the maximum percentages for sulfur and phosphorus are also specified.
For alloy steels, the first two digits of the SAE system describe the main alloying elements
present in the material, with the first digit indicating the group of alloys. For example, the 43XX
series steel grades contain 1.65-2.00% Ni, 0.50-0.80% Cr, and 0.20-0.30% Mo; manganese and
silicon content ranges and maxima for sulfur and phosphorus are also specified.
Additional letters added between the second and the third digits include “B” when adding
boron (0.0005-0.003%) for improved hardenability, and “L” when adding lead (0.15-0.35%) for
increased machinability. The “M” prefix is used to denote a high-grade quality steel (the least
restrictive quality characteristic for hot-rolled steel bars used in non-critical parts of structures and
mechanisms). The “E” prefix (steel for electric furnaces) and the “H” prefix (requirements for
hardenability) are mainly applicable to alloy steels. The full range of classification groups is shown
in Table 3.5.1.

UNS Designation System
The Unified Numbering System (UNS) is an alphanumeric notation system consisting of
letters and the five digits following them. This system only represents individual chemical
composition for metals or alloys and is not a standard or specification for a metal.
45
INTI R.00.1-2021
For the most part, the existing systems, such as the SAE designations, have been
incorporated into the UNS. For example, the UNS prefix for carbon and alloy steels is “G”, and
the first four digits are the SAE designation (for example, SAE 1040 steel grade is designated as
G10400 in the UNS system). The intermediate letters “B” and “L” in the SAE system are replaced
by adding the fifth digit in the UNS designation (1 and 4 respectively) while the prefix letter “E”
for electric furnace steel grades is designated in the UNS system by adding the fifth digit “6”. SAE
steels that have hardening requirements indicated by the “H” prefix are included in the Hxxxxx
series in the UNS system. Carbon and alloy steels not mentioned in the SAE system are classified
under the “K” prefix. Where possible, the first letter in the system designates a group of metals:
for example, “S” designates stainless steels. Of the five digits in the UNS designation for stainless
steels, the first three are the classification of SAE alloys: for example, S304XX. The last two digits
are equivalent to the various modifications represented by prefix letters in the SAE system, as
indicated in Table 3.5.1.

CARBON EQUIVALENT
Weldability of steels is determined by the value of the carbon equivalent Ceq,%, which
characterizes the risk of formation and development of cold cracks due to the occurrence of
quenching structures in the heat affected zone during welding of steel sheets. Knowing the carbon
equivalent value is essential, since in order to have high-quality welded joints it is required to
apply special techniques and methods in the manufacture of equipment: for instance, heating
(before and during welding), heat treatment (before and after welding), etc.
There are several formulas to calculate the carbon equivalent value.
The classical formula proposed by B.E. Paton:
Ceq = C+

.
(5.4)
In accordance with SA-20 (Supplementary Requirement S20), sheets of carbon steel grades
(including C-Mn, C-Mn-Si, C-Mn-Si-Al steels) shall be supplied with the carbon equivalent
determined, which shall not exceed the following values:
- if 415 ≤ σ ≤ 485 MPa, Ceq ≤ 0.45% for t ≤ 50 mm and 0.46% for t > 50 mm;
- if 485 ≤ σ ≤ 550 MPa, Ceq ≤ 0.47% for t ≤ 50 mm and 0.48% for t > 50 mm;
- if σ ≥ 550 MPa, then the Ceq ≤ 0.48% for t ≤ 50 mm.
Results of the required chemical tests and the carbon equivalent value shall be indicated in
the report. If post-welding heat treatment (PWHT) of test specimens is carried out (Supplementary
Requirement S3, SA-20), the maximum carbon equivalent value can be increased to 0.50 by
agreement between the customer and the supplier.
In Russian standards for sheet steel products, requirements for weldability assessment methods
are regulated in different ways. In accordance with GOST 14637 para. 2.1.4, “In rolled steel products
50
INTI R.00.1-2021
intended for welded structures, the mass fraction of carbon shall not exceed 0.22%”. In accordance
with GOST 5520 para. 7.1.7, “Weldability of steel is determined by its chemical composition and the
technology chosen for the manufacture of rolled steel products”. In accordance with GOST 19281
para. 5.2.1.2, “Steel products shall be supplied with a guarantee of weldability. Weldability is ensured
by manufacturing technology and compliance with the requirements for chemical composition, taking
into account the maximum deviations in the finished products, and limiting the carbon equivalent value
which shall not exceed, %:

In the SA-516 standard, there is an additional Supplementary Requirement S54 for carbon
steel sheets regulating their alkylation with hydrofluoric acid which requires that the sheets shall
be supplied in a normalized, heat-treated state. The maximum carbon equivalent (CE) shall be as
follows:
- if t ≤ 25 mm, then CE ≤ 0.43%;
- if t > 25 mm, then CE ≤ 0.45%.
Calculations of the carbon equivalent value are carried out in accordance with the formula
(5.4).
Also, based on the melt analysis results, the following conditions shall be met:
- content of vanadium and niobium shall be ≤ 0.02% for each element and 0.03% for their
total content;
- the total content of nickel and copper shall be ≤ 0.15%;
- the minimum carbon content shall be 0.18%, and the maximum carbon content shall
correspond to the steel grade specifications.

INTI R.00.1-2021
The filler material for repair welding shall have low hydrogen content. Using E60XX
electrodes is not recommended: the resulting chemical composition of the weld shall meet the
same chemical requirements as the base metal.
In addition to the product steel grade code requirements, each sheet shall be stamped or
marked “HF-N” to indicate that the sheet also meets the Supplementary Requirements.
Since the formulas for calculating the carbon equivalent are different, usually the developed
standards provide formulas for specific cases and describe the requirements for the calculation
results, so for pipes in accordance with TU 14-3R-1128-2007, the Ceq for steel grades 10, 20 is
calculated by the formula:
; and for steel grades 10G2A and 09G2C it is calculated
by the formula (10.4), and the Ceq value in accordance with the calculation results shall not exceed
0.43%.
For structural steels, the requirements for Ceq are provided in SP16.13330.2017 for steel
structures. The calculation is performed in accordance with the formula:
,

In addition, requirements for calculating the carbon equivalent value are specified in section
6 Weldability Groups.
Conclusions:
1)
As a rule, Russian manufacturers in their technical specifications for sheet steel also
indicate that weldability of steel is provided by its chemical composition and manufacturing
technology, so assessment of the carbon equivalent value can be carried out at the customer’s
request.
2)
Currently, assessment of the carbon equivalent value in accordance with the formula
of the International Institute of Welding (CEiiw) is most common.

WELDABILITY GROUPS
A metal is considered to be weldable to a specified degree in a given process and for a given
purpose when metal integrity is achieved by welding in the respective technology process, so that
the parts to be welded meet the established technical requirements both in terms of their own
qualities and in terms of their impact on the design they make.
This technical section provides a unified system for grouping materials by their welding
properties, covers various standardized systems and is developed on the basis of analysis and
systematization of normative and technical Russian and foreign documentation which is used for
development of welding technologies in the manufacture, installation, repair and renovation of
facilities, structures and equipment including hazardous production facilities.
Table 6.1 is based on the uniformity criterion which is a characteristic of the similarity of
conditions under which the welding technology process is performed. When developing programs
for welding procedure qualification, in accordance with RD 03-615-03, it is recommended to
distinguish between three types of welding technology:
Type I – technologies based on the use of general-purpose welding equipment, with the main
material, design and dimensions of the parts to be welded fully reproducing the process conditions
under which reference weld joints were made.
Type II – technologies based on the use of specialized welding equipment or on the use of
welding materials designed specifically for this technology.
Type III – technologies used in welding of parts, pieces and assemblies of complex design
and structure.
Proceeding from requirements for the manufacture, installation, repair and renovation of
various pieces of equipment of hazardous production facilities, taking into account similarity of
parameters and criteria for the same type of welded structures, they can be grouped into the
following four types:
Type I – installations consisting of pipelines and equipment;
Type II – installations consisting of sheet structures or structures made of profile rolled steel
items;
Type III – equipment of main and field pipelines;
Type IV – installation consisting of reinforcement units and embedded items of reinforced
concrete structures.
57
INTI R.00.1-2021
Welded joints of the same type shall be considered groups of welded joints that have
common basic parameters specified in the applicable regulatory documents for respective pieces
of equipment. It is allowed to combine welded joints of parts made of materials of different grades
of the same group into one group if requirements of the applicable welding specifications for these
parts allow the use of welding materials of the same grades (one or more). For the purpose of data
harmonization, this section takes into account provisions of international standards.
Welding technologies used in the manufacture of pieces of equipment of hazardous
production facilities (pipelines, vessels) by foreign manufacturers for delivery to Russia, and used
in the manufacture of pieces of equipment of hazardous production facilities by foreign
manufacturers on the territory of Russia, shall pass certification in accordance with RD 03-61503.
The main features that characterize weldability of steel grades are the tendency to form
cracks of various types and mechanical properties of the welded joint. In terms of their weldability
properties (Table 6.3), steel grades are divided into four groups: group 1 – good weldability; group
2 – satisfactory weldability; group 3 – limited weldability; group 4 – poor weldability [7]. Group
1 includes steel grades that can be welded using conventional technology, i.e. without heating
before welding and during welding and without subsequent heat treatment. However, the use of
heat treatment to relieve internal stresses may also be necessary. Group 2 includes steel grades
where cracks are not formed during welding under normal process conditions. This group also
includes steel grades that require preheating, as well as pre- and post-welding heat treatment to
prevent cracking. Group 3 includes steel grades that are prone to cracking under normal welding
conditions. These steel grades need to be heat-treated before welding and heated in the course of
welding. Also, most of the steel grades in this group require heat treatment after welding. Group
4 includes steel grades that are most difficult to weld and prone to cracking. These steel grades are
welded in exceptional cases with mandatory heat treatment before welding, heating in the course
of welding, and heat treatment after welding.
When welding carbon and alloy steels, weldability is determined by tests for the tendency to
form cold cracks. It is known that cold cracks occur in the heat affected zone in the presence of
three conditions: the formation of quenching micro-structures (martensite); the presence of
diffusive hydrogen; and tensile stresses. To assess propensity of a metal to form cold cracks, the
concept of the chemical carbon equivalent is used. The mathematical approach to description of
the chemical carbon equivalent is based on the assumption that weldability can be determined by
an indicator that determines what minimum critical cooling time is required for 100% martensite
58
INTI R.00.1-2021
to form in the weld metal. The longer the time required for 100% of martensitic structure to form
(i.e., the higher the critical cooling rate is), the better weldability and the higher resistance to cold
cracking are. This indicates that the preparatory processes associated with the formation of cold
cracks are diffusive in nature, and are directly related to redistribution of hydrogen in the weld
metal. In the case of a short incubation period (1-10 sec.) required for the formation of martensite,
hydrogen is quickly fixed in the weld metal but its local concentration is insufficient to initiate the
formation of cold cracks. In the case of a long incubation period (1000-2000 sec) required for the
formation of martensite, the time is quite sufficient for embrittlement of the welded metal as a
result of the action of hydrogen. With a short incubation period but subsequent long exposure, a
gradual redistribution of hydrogen is possible, which causes the effect of delayed destruction.
In many cases, the quantity of carbon in steels determines the main performance
characteristics of the alloy. Too high concentration leads to increased hardness and strength, but
also increased brittleness. In addition, weldability is reduced by several times (Table 6.2).
However, there are other systems for calculating the carbon equivalent, where alloying
components are taken into account to a greater extent than in the example shown earlier. Such
systems can be used to calculate the carbon equivalent for carbon and low-alloy steels (Table 6.5).

6.1 Weld Tempering Embrittlement Characteristics
Tempering cracks in welding are formed in the course of heat treatment performed after the
end of the metal welding process. This is usually a tempering procedure performed to relieve
residual internal stresses in the weld and the heat affected zone.
Tempering cracks occur when welding low-alloy steels, austenitic steels (chromium-nickel)
and nickel alloys.
There are three types of tempering cracks:
1.
Low-temperature tempering cracks formation of which is similar to formation of cold
cracks, at low temperatures of about 200-300°C.
2.
High-temperature tempering cracks which are formed at temperatures of 500-700°C.
3.
Cracks formed under weld beads. They often appear when welding low-alloy steels
using strip austenitic electrodes.
Among these three types of cracks, the biggest ones are low-temperature cracks. Regardless
of the type, all tempering cracks, without exception, reduce operational properties of welded
products.
Tempering cracks of the first type, which form at low temperatures, occur due to high heating
rates. As a result, there is a large temperature difference between the surface and the interior of the
welded item which causes thermal stresses. These stresses begin to affect those parts of the heat
affected zone that have already been weakened during the welding process. Often, tempering
cracks occur as a result of formation of hot cracks in the course of welding. If there are signs of
hot cracks in the metal in the course of welding then during tempering, at a high heating rate, they
can develop as tempering cracks. Also, tempering cracks can be a continuation of the cold cracks
development process.
Often it turns out that before the tempering operation it is impossible to detect signs of hot
and cold cracks by the use of flaw detection methods. So after the tempering process, or in the
course of it, such cracks develop as tempering cracks.
To avoid such defects in welds, it is required, first of all, to avoid fast heating in the course
of the tempering process. It is required to adjust the heating speed, first of all, at the initial stage
of heating, up to 300°C. In the case of welding parts with thick walls, the recommended heating
speed shall be within 15-30°C.
Also, formation of tempering cracks can be prevented by using post-weld heating and
temperature control in the intermediate layers. With this welding technology, the product does not
72
INTI R.00.1-2021
cool down at the end of welding. Temperature of the intermediate layers is 150-300°C. At such a
residual temperature, it is required to start the tempering process immediately.
Besides, formation of cracks in the course of tempering can be prevented if cold and hot
cracks are avoided during welding. Also, it shall be noted that any stress concentrators have a
significant negative effect on welds. Therefore, it is required to perform their surface treatment
and pay attention to the geometry of the weld.
High-temperature tempering cracks appear due to overheating of the heat-affected zone,
which has a coarse-grained structure. The reason for the occurrence of such cracks is due to the
phenomenon of tempering brittleness of steel. Chemical composition of steel and deoxidation of
metal in the course of welding have a great influence on their formation. For example, with a small
increase in the content of copper and antimony, the risk of high-temperature cracks increases and
with an increase in tin in the composition it decreases. Deoxidation with aluminum, if its content
exceeds 0.035%, is unfavorable, and deoxidation with titanium is favorable. With an increase in
the total content of phosphorus, copper, tin, antimony and arsenic from 0.5% to 1.3%, and with an
increase in grain size, the risk of high-temperature cracks increases. Vanadium and chromium,
with their content of more than 2%, in low-alloy steels, has a negative effect. The influence of
molybdenum and nickel is positive, although there is no consensus on this issue.
Evaluation of the tendency of a welded joint to form high-temperature cracks can be
determined by the formulas developed by Nakamura and Ito:
G=Cr+3.3Mo+8.1V+10C-2 is the Nakamura formula;
PSR=Cr+Cu+2Mo+10V+7Nb+5Ti-2 is the Ito formula.
If the values of G and PSP are positive the steel is considered to be prone to cracking in the
course of tempering.
It is also recommended to use international formulas for determining the low temperature
embrittlement values Watanabe (J) and Bruscato (X):
J = (Mn + Si)(P + Sn) x104;
X = (10P + 5Sb + 4Sn + As) / 100.
In addition to the influence of alloying elements on weldability, the welding technology
itself, namely, the cooling time, is of great importance. The longer the required cooling time, the
higher the tendency of the metal to form tempering cracks.
73
INTI R.00.1-2021
Cracks under the weld bead are formed in the process of build-up welding of low-alloy steels
with strip austenitic electrodes. As a rule, it relates to submerged arc welding. Such cracks are
inter-crystalline fracture in the superheat zone which is subject to the thermal effect of building up
the next weld layer. Occurrence of such cracks can be avoided by normalizing the overheated zone.
This can be done in the course of a two-layer build-up welding. With this technology, the first
build-up is performed at a reduced welding power, and the second, on the contrary, at an increased
welding power to expand the normalization zone. Also, the superheat zone can be normalized by
induction surface heating. Besides, there is a way to exclude the appearance of tempering cracks
in the weld bead if a ferritic layer is used instead of the first, austenitic layer.

WELDING MATERIALS
7.1 Analogs of Foreign and Russian Base and Welding Materials Used in the
Manufacture of Vessels, Apparatus and Pipelines Inspected and Supervised by
Rostechnadzor
This section is compiled in accordance with STP 26.260.486-2005. The standard applies to
the choice of welding material analogs in the manufacture of vessels, apparatus and pipelines for
the petrochemical, gas processing and other related industries.
Welding materials of the following foreign companies are reviewed: ESAB and ELGA
(Sweden), BÖHLER (Austria, Germany), LINCOLN (USA), OERLIKON (Germany), KOBE
(Japan).
The choice of the cataloged foreign grades of welding materials, as Russian analogs, shall
be made depending on whether the steel to be welded belongs to a steel group composed by the
criterion of similarity of respective welding materials taking into account operating parameters
and conditions of vessels and pipelines for the assembly of which such welding materials are to be
used.
Conditions for the use of foreign steel grades and welding materials listed in the catalog
correspond to conditions for the use of similar Russian materials in accordance with the following
regulatory documents: GOST 34347, STO 00220368-013-2009, ОSТ 26.260.3-2001, ОSТ
26.260.480-2003, STO 00220368-012-2008, STO 00220575.063-2005, РТМ 26-320-79, STO
00220368-011-2007, STO 00220368-008-2006, STO 00220368-016-2009.
When choosing welding materials, it is required to take into account that conditions of
application of welded structures are determined both by conditions of application of the steels to
be welded and conditions of application of respective welding materials.
This Guide specifies foreign and Russian analogs of welding materials for manual arc
welding, automatic submerged arc welding, and gas-shielded welding, and provides indexing of
foreign steels and welding materials used in accordance with the U.S. ASTM and AWS standards.
Information in this section allows one to select base and welding materials supplied by other
foreign companies, not mentioned in this document, by types specified in the catalogue of
materials; in doing this, one shall follow the requirements for special-purpose welding materials,
for example, welded joints operated at low and high temperatures, in environments that cause
stress corrosion cracking, etc.
The welding materials listed in this Guide intended for welding high-alloy steels of the
austenitic class are also used for application of a corrosion-resistant layer in the cladding of
pearlite-class steels.
75
INTI R.00.1-2021
Similar groups of foreign (the U.S. ASTM standards and standards of other countries) and
Russian (GOST) steel grades welded by the same types of foreign (in accordance with U.S. AWS
standards) and Russian (GOST or TU) welding materials is specified in Table 7.1. To identify
foreign base and welding materials, the U.S. standards have been taken, since the catalogs and
certificates for supply of almost all foreign materials confirm their compliance with the U.S.
standards.
Foreign AWS e7024, E7027, E7028 electrodes, depending on their grades, can correspond
to Russian E46A or E50A electrodes. Instead of Russian electrodes of E46A type, foreign
electrodes designed for welding S-02 group steel grades can be used.
Steel grade 20YuCh intended for the manufacture of vessels and apparatus operating in
hydrogen sulfide-containing media that cause corrosion cracking is conditionally included in
group S-02 as being welded with the same type of welding materials used for welding steels of
this group, i.e. foreign steel grades of group S-02 cannot be considered as the analogs of steel grade
20YuCh.
Welding materials intended for welding of S-02 group steel grades can be used for S-01
group steel grades.
Welding materials intended for welding S-09 group steel grades, under certain conditions,
can be used for S-04, S-05 and S-06 steel grades, formation of the transition layer in double-layer
steels, build-up welding of the transition layer when cladding pearlite-class steels with corrosionresistant steels, and for welding of dissimilar steels (S-01, S-02, S-03, S-04, S-05, S-06 + S-07, S08, S-09).
Welding materials designed for welding S-07 and S-08 group steel grades are also used for
welding the cladding layer of double-layer steels and build-up welding a corrosion-resistant layer
when cladding pearlite-class steels.
Welding materials designed for welding of steel grades resistant to inter-crystalline corrosion
(ICC) can be used for steel grades that are not resistant to ICC.
Foreign analogs of Russian steel grades 08X22N6T and 08X21N6M2T are not included in
the nomenclature of foreign products. For welding of the specified steel grades, foreign welding
materials intended for welding of steels of groups S-07 and S-08, respectively, can be used.
Table 7.1 shows the types of deposited metal for automatic submerged arc welding, gasshielded welding, and manual arc welding in accordance with the U.S. AWS standard. Types of
electrodes in accordance with Russian standards are conditionally equated to the type of deposited
metal when using foreign welding materials.

7.2 Requirements for Welded Joints and Welding Procedure
Welded structures shall be designed taking into account the rational use of combinations of
dissimilar steels and performing the maximum amount of welding work at the manufacturer’s
production facility.
When designing critical (working under load) structures made of dissimilar steels of
different structural classes, it is recommended to:
- prefer butt joints to other types of joints: angular, T-shaped, lap. Location of welds shall
ensure the convenience of welding operations, reliability of the finished weld;
- position welds of dissimilar materials in the least loaded areas of the structure and in areas
not exposed to high operating temperatures;
- exclude, as much as possible, the presence of stress concentrators in the area where
dissimilar materials are welded;
- provide for effective control for the absence of unacceptable external and internal defects;
- adopt structural and other solutions that exclude the need for heat treatment;
- exclude heat treatment of welds made of dissimilar materials including heat-resistant or
high-chromium stainless steels, and carbon and low-alloy steels with a thickness of more than 30
mm, with the use of austenitic welding materials;
- for high temperatures and difficult operating conditions, intermediate structural elements
made of more stable steels or build-up welding shall be used in order to limit development of
brittle layers.
When developing the welding process for dissimilar steels, the following shall be taken into
account:
- technology-related features (weldability) of steels and alloys, special requirements
(heating, heat treatment, etc.) that are necessary for welding of dissimilar materials in accordance
with the applicable regulatory and technical documentation for welding both such dissimilar
materials;
- possibility of defects, especially cold and hot cracks, specific to each of the dissimilar
materials to be welded;
- possibility of formation and development of structural inhomogeneities (diffusion and
crystallization layers);
- need for and sufficiency of measures to ensure proper mechanical properties and corrosion
resistance of welded joints.
80
INTI R.00.1-2021
The maximum operating temperature of welded joints made of dissimilar steel grades of
austenitic class and carbon and low-alloy manganese-silicon steel grades of pearlitic class shall
not be higher than the lowest of the temperatures permissible for both steels but in any case it shall
not higher than 470°C.
The minimum operating temperature shall not be lower than the highest temperature
permissible for both steels but in any case it shall not be lower than minus 40°C. Welded joints
made of dissimilar steels containing 60% nickel may be operated at temperatures not lower than
minus 60°C.
Note: Welded joints made of dissimilar steels containing 40% nickel are allowed to be used
at temperatures down to minus 60°C provided that the weld penetration rate of pearlite steel is ≤
20%.
The maximum operating temperature of welded joints made of austenitic steels and
chromium-molybdenum steels of pearlitic and martensitic classes shall not be higher than the
lowest of the permissible for both steels but in any case it shall not higher than 600°C. The
minimum operating temperature shall not be lower than 0°C.
When welding steels of the same structural class of different grades, it is allowed to use one
of the welding materials recommended for welding any of these grades.
When making welds of dissimilar materials such as carbon (S-01) and low-alloy (S-02, S03) steel grades (pearlitic class) with low-alloy pearlitic steel grades (S-02, S-03, S-04) and
medium-alloy martensitic steel grades (S-05), preference shall be given to more technologically
advanced welding materials which, as a rule, are lower alloyed, have lower instantaneous strength,
higher ductility and higher viscosity of the weld metal. In some cases, for specific operating
conditions, it is allowed to use austenitic welding materials in which case the welding technology
shall be agreed upon with a specialized research organization.
When making welds of dissimilar materials such as high-alloy corrosion-resistant steel
grades of austenitic and austenitic-ferritic class (S-07, S-08, S-09), alloys (S-10) with pearlitic
steel grades (S-01, S-02, S-03, S-04), martensitic (S-05), ferritic, martensitic-ferritic and
martensitic (S-06) classes preference shall be given to lower alloyed welding materials that provide
austenitic structure of the weld metal with a ferrite content of at least 2%. The upper limit of the
permissible ferrite content depends on the operating temperature of the welded joint and shall not
exceed the values specified in Table 7.2.1.

Heat resistant steel grades of pearlitic and martensitic classes (S-04-1, S-04-2, S-05) and
high-chromium steel grades of ferritic, martensitic-ferritic and martensitic classes (S-06), when
being welded with steel grades of other structural classes, require heating in accordance with
Tables 7.3.2, 7.3.3 and 7.3.4. The exception is steel grades of pearlitic class (S-04-1) like 12XM
as well as ferritic and martensitic-ferritic classes at a wall thickness of ≤ 10 mm. It is allowed to
weld heat-resistant steel grades of pearlitic and martensitic classes (S-04-1, S-04-2, S-05) and
high-chromium steel grades of ferritic, martensitic-ferritic and martensitic classes (S-06),
regardless of the wall thickness, without heating when using welding materials containing at least
40% nickel.
The heating temperature shall be controlled by means of contact or non-contact infrared
thermometers, thermal pencils, thermal paints, digital contact and laser non-contact
thermocouples.
Temperature measurements shall be made within the uniform heating zone at a distance of
at least two wall thicknesses in each direction from the weld axis.
Welding of dissimilar steel grades of austenitic and austenitic-ferritic classes (S-07, S-08)
with alloys (S-10-1, S-10-2) is recommended to be made with welding materials intended for
welding of iron-nickel-based alloys, and welding of alloys of group S-10-1 with alloys of group
S-10-2 is recommended to be made with welding materials intended for welding of nickel-based
alloys giving preference to welding materials intended for a specific weld alloy.
When using austenitic welding materials for welding of dissimilar materials, including heatresistant steels (S-04, S-05), and steel of ferritic, martensitic-ferritic and martensitic classes (S-06)
subject to heat treatment in accordance with the design requirements, it is recommended to use
welding materials containing at least 40% nickel (ANZhR-1, ANZhR-2, Sv-08X20N60M10, Sv08X25N40M7, etc.).
Austenitic welding materials containing at least 40% nickel are allowed to be used for
welding of dissimilar materials including heat-resistant steels which are operated in environments
that cause corrosion cracking.
Heat treatment shall be performed for welded joints made of dissimilar materials, including:
- steels of groups S-01, S-02, S-03 at a wall thickness of more than 30 mm, welded per the
pearlitic scenario;
82
INTI R.00.1-2021
- steels of groups S-04, S-05, except for steels of the pearlite class of type 12XM (S-04-1)
at a thickness of up to 10 mm, welded on pearlite material;
- steels of groups S-07, S-08 or alloys of groups S-10-1, S-10-2 if there is a requirement for
resistance to ICC.
The need for heat treatment of welded joints of dissimilar steels shall be established at the
design stage of welded units of apparatus and pipelines.
When using austenitic welding materials containing 12-14% nickel to make welds of
dissimilar materials such as steel grades of groups S-01, S-02, S-03, S-04, S-05 and S-06 with
other groups of materials, it is required to take measures to limit the share of non-austenitic steel
(≤ 30%) in order to limit martensite in the weld metal and prevent cold cracks, which can be
achieved by:
- the use of manual arc welding and argon arc welding with a non-consumable electrode,
semi-automatic welding in argon and argon-based gas mixtures (Ar + 20% CO2, Ar + 5% O2, etc.),
automatic submerged arc welding at direct current of straight polarity;
- the use of special process methods such as preliminary build-up welding of edges, limits
on welding parameters, etc.
Note: The penetration rate shall be controlled experimentally when selecting the welding
conditions and in the course of the welding process, by weld metal hardness measurements or
metallographic methods.
When welding non-austenitic steels with the use of austenitic welding materials, it is
recommended that the root part of the weld, without subsequent removal of metal from the reverse
side, is made with the use of welding materials containing at least 40% nickel.
When welding dissimilar steels using welding materials containing 40% nickel or more, it
is required to take measures to prevent the formation of hot cracks (welding shall be performed
with narrow rollers of limited compact cross-section, without transverse vibrations of the
electrode, with the highest possible speed; in case of automatic submerged welding, AN-18 flux
shall be used; prior build-up welding of edges; careful repair of arc scars, etc.).
Welding of heat-resistant steels of groups S-04-1, S-04-2 and S-05 is made with the use of
pearlite welding materials intended for lower alloyed steel grades with post-weld heat treatment
of welded joints made of dissimilar materials. In case of austenitic welding materials, it is allowed
not to heat-treat the welds.
Welding of martensitic steel grades with the use of austenitic welding materials is allowed
if the content of emulsified water in oil products is ≤ 0.2%, content of chloride salts is ≤ 10 mg/l,
and content of caustic soda is ≤ 30 g/t of oil product.
83
INTI R.00.1-2021
Using austenitic welds is not allowed:
- in areas of separation of water from oil products;
- for making longitudinal welds of pipe elements and shells.
To weld pipe elements of catalytic reforming units operating in the oxychlorination process,
welding materials containing at least 40% nickel shall be used.
When welding dissimilar materials, including steel grades of pearlitic (S-01, S-02, S-03, S04-1, S-04-2) and martensitic (S-05) classes at a wall thickness of more than 12 mm, austenitic
welding materials are recommended to perform prior build-up welding of edges in order to:
- save expensive high-nickel welding materials;
- reduce chemical and thermos-physical heterogeneity of joints;
- increase process strength (resistance to cold and hot cracks) of welds made of dissimilar
materials.
Note:
1. Build-up welding of edges with the use of welding materials containing up to 25% nickel
shall be made with heating the metal to 150-200°C;
2. Heat treatment of welded joints in this case is not required.
When welding dissimilar heat-resistant steel grades of pearlitic and martensitic classes
(groups S-04-1, S-04-2, S-05), it is allowed to make prior build-up welding of the weld root with
electrodes of E42A type, followed by filling the weld preparation groove with austenitic welding
materials. Such welds can be operated in environments that cause corrosion cracking at
temperatures up to 260°C.
When welding dissimilar materials such as heat-resistant steel grades (S-04-1) with carbon
steel grades (S-01), it is allowed to cover the edges of welded parts made of heat-resistant steel
grades with electrodes of E42A or E46A types, followed by filling the weld preparation groove
with the same welding materials.
Notes
1. Build-up welding of the edges shall be made with heating to 200-250°C;
2. Heat treatment of welded joints in this case is not required.
Build-up welding of the edges shall be made at least in two layers. Thickness of the buildup weld after mechanical treatment shall be 5 ±1 mm for manual arc welding, argon arc welding
or semi-automatic welding in argon and gas mixtures based on argon (AG + 20% CO2, AG + 5%
O2, etc.) and 6 ±1 mm for automatic submerged arc welding or semi-automatic welding in carbon
dioxide.

INTI R.00.1-2021
Welding parameters and conditions of pre-weld heating, in-process heating, and post-weld
heat treatment shall be applied taking into account weldability of the most difficult steel grade of
those being welded in accordance with the requirements of OST 26.260.3, OST 26.260.480, STO
00220368-008, RTM 26-44. Weldability characteristics of various steel groups and respective
technology requirements are specified in Table 7.2.2.

For welding of parts and assemblies made of dissimilar steels and alloys, the recommended welding materials are specified in Tables 7.3.2,
7.3.3 and 7.3.4.
Steel grade 08X13 (S-06) and welded joints of this steel are used for unstrained structures.
When making welds of dissimilar materials of the same structural class with the use of welding materials of another structural class, any welding
materials used for making welds of dissimilar materials of different structural classes, including materials of the same structural class, can be used.
For example, to weld steel grade St.3 with steel grade 12XM, in addition to welding materials intended for welding of carbon and low-alloy steels,
austenitic welding materials can be used.
As a non-consumable electrode for argon arc welding, lanthanated tungsten electrodes in accordance with GOST 23949 with a diameter of 2-4
mm or thoriated (2%) shall be used.
Tungsten electrodes shall be sharpened conically to an angle of 15°. Before each pass, the sharpening shall be inspected, and if the end of the
tungsten electrode is damaged or contaminated it shall be replaced or the sharpening shall be restored.
In argon arc welding, argon of the highest grade in accordance with GOST 10157 shall be used as a shielding gas.

7.4 Analogs of Foreign and Russian Welding Materials for Submerged Arc Welding
Grades of foreign and Russian welding materials used for automatic submerged arc welding
of various groups of steels are listed in Table 7.4.1.
It is allowed to use a combination of a flux and a wire of the same type produced by different
manufacturers.
The welding materials listed in the Catalog, intended for welding of austenitic steels, can be
used for applying anticorrosive coatings on parts made of low-carbon and low-alloy steel grades
(pipe grilles, fittings, body flanges, shells, bottoms). At the same time, building up the transition
layer shall be made with welding wires of Sv-07X25N12G2T type (ER309 or ER309L per AWS)
at a direct current of straight polarity.
For application of a cladding layer, welding wires of the same type shall be used, depending
on requirements for the deposited metal. The application process shall be performed with direct
current of straight polarity.
For application of anticorrosive coatings, welding wires can be replaced with welding strips
of the same type.
At direct current of straight polarity, build-up welding with welding strips is made under
flux type FC-18 per OST 24.300.04-91 (PFB-1, Japan; BB 500, Austria).

Notes:
To weld steel grades of group S-02, PITTARC S2 welding wire (SIAT SpA, Italy) can be used as an analog of Russian welding wire Sv-10GA.
To weld steel grades of group S-03, PITTARC S3Si welding wire (SIAT SpA, Italy) can be used as an analog of Russian welding wire Sv-10G2.

INTI R.00.1-2021
7.5 Analogs of Foreign and Russian Welding Materials for Gas-Shielded Welding
When ordering welding wire for gas-shielded welding from a foreign manufacturer, the form
of the product (coils, reels or rods) shall be agreed upon.
Welding wires and filler rods designed for each group of steels to be welded in view of
applicable requirements for operating conditions (temperature, environment), are listed in Table
7.5.1 in two lines: the upper line lists wires for welding with consumable electrodes; the lower line
lists wires and rods for argon arc welding with non-consumable electrodes.
Welding wires designed for welding with consumable electrodes to make welds operated in
environments resistant to SCC can be used in combination with a shielding gas – argon or an
argon-based gas mixture. Welding in CO2 is allowed only to weld internal parts and their
supporting elements to tanks and vessels made of steel grade 20YuCh and the like.

Content of the ferritic phase in the deposited metal of welded joints made with austenitic welding electrodes and operated at temperatures of up to
350°C shall be more than 1.5% to ensure their resistance to hot cracks, and ≤ 8-10% at operating temperatures over 350°C to prevent hightemperature embrittlement, but in any case it shall not exceed the values of the upper limit set in the standards or technical specifications for
respective welding electrodes.

Notes:
Semi-automatic welding in CO2 with Sv-08G2S welding wire (wire diameter of 0.8-1.2 mm) is allowed for welding of tanks and vessels operated
at temperatures down to minus 60°C.
For welding of tanks and vessels operated in environments that cause SCC, semi-automatic welding in CO2 and gas mixtures is allowed only to
weld internal and external parts, and argon arc welding with a non-consumable electrode is allowed to weld the root when making one-sided weld
joints.
Welding wire Sv-07X25N12G2T, as well as its foreign analogs, can be used to weld dissimilar steel grades operating at temperatures up to 400°C;
welding wires Sv-10X16N25AM6 per GOST 2246 or welding wire ER309 per AWS A5.9, welding wire Sv-08X25N60M10 per TU 14-1-4968-91
or welding wire ERNiCrMo-3 per AWS 5.14 can be used for the same purpose with a temperature limitation in accordance with API RP 582.
In the case of using austenitic welding wires to weld steel grades 12XM, 15 XM, 15X5M and 08X13, heating is required only when the weld beads
are applied directly on the surface of these steels; once the surface is built up to a thickness of 6 mm or more, welding is performed without heating.
Content of the ferritic phase in the deposited metal of welded joints made with the use of austenitic welding materials and operated at temperatures
up to 350°C shall be more than 1.5% to ensure their resistance to hot cracks, and ≤ 8-10% at operating temperatures over 350°C to prevent hightemperature embrittlement, but in any case it shall not exceed the values of the upper limit set in the standards or technical specifications for
respective welding materials.

APPLICABILITY OF STEEL GRADES DEPENDING ON CORROSION
PROCESS
This section deals with corrosion processes caused by exposure of steels and alloys to carbon
dioxide, hydrogen sulfide, hydrogen, bases and glycols. It also specifies types and grades of steels
resistant to various types of corrosion.
8.1 Carbon Dioxide Corrosion
Carbon dioxide corrosion mainly affects low-alloy carbon steels. This type of corrosion is
realized by an electrochemical mechanism, when water in liquid form is present in the working
medium, and carbon dioxide (CO2) is also present. When dissolved in water, CO2 dissociates with
the formation of weak carbonic acid due to which pH factor of the solution is reduced and the
medium becomes more acidic:
+
→ [H] +
Corrosion rate can be calculated by the de Waard-Milliams equation [4 and 5], and the corrosion
process can be modeled in accordance with the Norsok M-506 standard [2] with the use of correction
factors depending on additional conditions, for example, the presence of other components. Based on
the corrosion rate (mm/g) and the design service life of equipment, an increase in wall thickness is
assigned to compensate for corrosion which is called the corrosion allowance (CA).
A typical case here is the use of carbon and low-alloy steel grades (GS and the like) at a
corrosion rate of up to 0.3 mm/year depending on the service life of the structure; for example, the
service life of the pipeline is 20 years and the corrosion rate is 0.3 mm/year. If the corrosion rate
is higher than 0.3 mm/year determined for carbon steel grades, a reasonable option is to use highalloyed steels with a chromium content of 18% and nickel content about 10% depending on the
service life of the structure; for example, the service life of the pipeline is 25 years and the
corrosion rate is 0.3 mm/year.
Stainless steel grades 08X18N10, 08X18N10T, 12X18N10T, AISI (304, 321), X5CrNi1810/1.4301, X6CrNiTi18-10/1.4541, etc. are most resistant to carbon dioxide corrosion due to the
content of alloying elements. However, conditions for the use of steel grades in each particular
case shall be considered individually, and usually depend on many factors. Besides, flow rate of
the working medium plays a significant role in the rate of corrosion in the carbon dioxide
mechanism, and with an increase in the flow rate, corrosion and erosion wear (CEW) may occur.
To prevent erosion wear, the maximum speed of the medium is calculated in accordance with API
RP 14 E.
138
INTI R.00.1-2021
8.2 Hydrogen Sulfide Corrosion
Hydrogen sulfide causes a number of corrosion-related problems. These include damages
that occur at relatively low temperatures, when formation of water in liquid phase is possible
(general corrosion, pitting corrosion, corrosion cracking). These damages are caused by
electrochemical corrosion.
The rate of general electrochemical corrosion for carbon and low-alloy steels depends on
many factors, and, as a rule, does not exceed 0.2-0.3 mm/year. However, with development of
pitting corrosion spots the rate of corrosion reaches 2.5 mm/year and may even exceed this value
[10].
In a gas saturated with moisture (below 90%), regardless of the partial pressure of hydrogen
sulfide, the surface is passivated, the corrosion process is slowed down by the formation of a film
of iron sulfide which is a product of the corrosion process. As humidity increases, the structure of
the film is disturbed, the corrosion rate increases, and at 100% humidity it reaches its maximum
values.
In liquid hydrogen sulfide-containing media, corrosion develops 3-10 times faster than in
gas media. Liquid two-phase systems containing a hydrocarbon phase along with water are
particularly aggressive [10].
Wet hydrogen sulfide not only causes electrochemical corrosion but also contributes to
absorption of hydrogen released from the cathodic process by the metal corrosion processes. All
this results in such a type of damage as hydrogen sulfide corrosion cracking. This damage is
characteristic for ferritic-pearlitic steel grades and especially for those with elements of brittle nonequilibrium structures (bainite and martensite).
Assessment of aggressiveness of hydrogen sulfide-containing media determined in
accordance with GOST R 53679 (ISO 15156-1) in respect of the occurrence of stress-induced
hydrogen sulfide corrosion cracking (SCC) of carbon and low-alloy steel grades is carried out on
the basis of (or using) Figure 8.2.1 [12]. For oil refineries, ISO 17945 shall be followed.

The most efficient method of protection against hydrogen sulfide electrochemical
corrosion is the use of appropriate materials and inhibitory protection, in which kinetics of the
processes occurring during hydrogen sulfide corrosion is suppressed with the help of special
agents (inhibitors).
In a dry gas, corrosion damage of metal does not occur due to the absence of an
electrochemical process but may occur at high temperatures.
High-temperature corrosion caused by hydrogen sulfide (or all sulfur-containing media)
is usually realized at ambient temperatures above 260°C. Sulfur compounds contained in
process media react with the metal surface at high temperatures and form sulfides.
This process, as a rule, manifests itself in the form of uniform corrosion. In the presence
of impurities such as naphthenic acids, corrosion can be local or express in the form of
corrosion-erosion wear. The rate of corrosion depends on sulfur concentration, working
temperature and the selected material.
At temperatures above 260°C, the corrosion rate of carbon steel increases exponentially
as the temperature rises to about 455°C. Above 455°C, it slows down somewhat due to
deposition of coke which together with iron sulfides forms a dense layer [10]. By addition
chromium to steel, its resistance to high-temperature hydrogen sulfide corrosion can be
increased.
Table 8.2.2 shows corrosion rates as a function of hydrogen sulfide partial pressure and
temperature. This table is based on Figure 8.2.2 taken from the literature [10].

Exposure to hydrogen sulfide may cause dangerous types of corrosion damage such as
sulfide stress corrosion cracking (SSC) and hydrogen-induced cracking (HIC) in addition to the
destruction mechanisms mentioned above.
Sulfide stress cracking is the brittle fracture of a metal under the effect of tensile stress and
corrosion in the presence of hydrogen sulfide and water. The tensile stress can be the sum of the
external stress (for example, from pressure) and the residual stress after welding or cold
deformation. In the NACE MR-0175 standard, it is assumed that the minimum partial pressure of
gaseous hydrogen sulfide at which SSC is possible is 345 Pa.
The risk of SSC increases with an increase in partial pressure of H2S, increase in the solution
acidity (decrease in pH), increase in the tensile stress, and increase in strength characteristics of
the steel.
Sulfide stress cracking is the most dangerous type of corrosion failure. Inhibition and
protective coatings can reduce metal hydrogenation and reduce the risk of SSC but these methods
are not considered reliable enough. Therefore, if the medium is capable of causing sulfide stress
cracking of steel then the structure shall be made of a material resistant to SSC regardless of what
other corrosion protection methods are planned to be used.
Hydrogen-induced cracking is particularly dangerous for rolled carbon and low-alloy steel
sheets. Sheet steel products can be subjected to hydrogen-induced cracking (HIC) at very low
concentrations of H2S even in the absence of tensile stresses. With an increase in the hydrogen
sulfide partial pressure PH2S and the solution acidity, the threat of HIC also increases.
The probability of HIC depends on chemical composition of the steel and the method of its
manufacture. Of particular importance are the sulfur content in steel and the shape of non-metallic
inclusions. The permissible sulfur content for rolled and seamless products working in media with
a hydrogen sulfide partial pressure of 0.1 MPa are 0.006% and 0.010% respectively in case of a
globular form of non-metallic inclusions, due to addition of rare earth elements or treatment of
liquid metal with calcium.
142
INTI R.00.1-2021
A number of sources [18] suggest that hydrogen-induced cracking of steels can only occur
at PH2S ≥ 0.0003 MPa, i.e. at the same PH2S as for SSC. However, [17] states that a partial pressure
of gaseous H2S equal to 0.0001 MPa is a safe pressure that does not cause HIC. At normal
temperature (~30 °C), this corresponds to a H2S concentration in the aqueous phase of 3 mg/l.
The possibility of HIC also depends on chemical composition of steel and the manufacturing
technology of the equipment. Of particular importance is the sulfur content in steel. Carbon and
low-alloy steels are considered insensitive to HIC at the following sulfur contents:
- flat rolled products ≤ 0.003%;
- seamless pipes ≤ 0.01%;
- forgings ≤ 0.025%.
At a higher content of sulfur in steels, the possibility of HIC is not excluded even in case of
a low content of hydrogen sulfide in the working environment.
The hydrogenation capacity of media containing hydrogen sulfide increases with the
increase in PH2S, solution acidity and temperature.
Hydrogen-induced cracking, in contrast to sulfide stress cracking, develops relatively slowly
and can be detected by ultrasound scanning. Detection of HIC shall be a mandatory element of
corrosion control in transportation and processing of gases containing hydrogen sulfide.
Resistance of carbon and low-alloy steels to sulfide stress cracking (SSC) and hydrogeninduced cracking (HIC) depends on their chemical composition and structure, the number and
shape of non-metallic inclusions, strength characteristics, level of deformation and internal stresses
in the metal, the presence of welds, heat treatment, the presence of stress concentrators, etc.
Creating a fine-grained structure (at least 7 points in accordance with GOST 5639), reducing
contamination with non-metallic inclusions, limiting the content of S and P, treating steel with
calcium or rare earth metals to globalize non-metallic inclusions, relieving internal stresses from
deformation and post-welding stresses by heat treatment, limiting the hardness of the base metal
and welds reduces the tendency of steels to sulfide stress cracking and hydrogen-induced cracking.
Preference shall be given to steel grades whose resistance to SCC is confirmed by results of
many years of successful operation in hydrogen sulfide-containing media. For such steel grades
(for example, Russian steel grade 20YuCh), laboratory tests for resistance to SCC is not required.
It shall be ensured by the manufacturing technology.
8.3 Hydrogen Corrosion
Hydrogen corrosion (cracking) of carbon steel at high hydrogen pressure is possible at
temperatures from 200-230°C [10].
143
INTI R.00.1-2021
Hydrogen cracking is the result of diffusion of atomic hydrogen in the metal, including due
to the corrosion reaction between H2S and Fe. However, in this case, tensile stress is not a
mandatory condition.
In addition to increasing wall thickness, an important provision that ensures reliable
operation of equipment is the use of alloy steels in the manufacture of such equipment. Adding
carbide-forming elements into the metal can significantly increase resistance of the metal to
hydrogen corrosion. When choosing materials, the Nelson curves are widely used (see Figure 8.3.1
or API 941), which allow determining the range of resistance of various structural materials to the
effects of hydrogen in a wide range of hydrogen temperatures and partial pressures [10].

8.4 Acid-Base Corrosion
Problems associated with the impact of acid-base solutions on pipelines occur most often in
oil refineries due to an excessive use of alkaline solutions in the process of alkalization of the
feedstock or overhead distillates, and in acid gas removal units of gas plants due to the use of
organic bases – alkanolamines – as absorbers.
Corrosion caused by the impact of acid bases, as a rule, is of pitting character or appears in
the form of alkaline corrosion cracking (ACC). As a result of secondary reactions, iron hydroxides
are formed which later decompose into oxides that interfere, to a greater or lesser extent, with the
anode process.
At a pH factor of the medium above 8.5, the steel surface potential reaches the values of the
passivation potential, and the corrosion rate of carbon and low-alloy steels begins to slow down.
At the same time, there is a danger of pitting corrosion on the surface.
Reducing the level of stress in the metal significantly expands the possibilities of using
carbon steels in alkaline solutions. Since most often ACC develops in the heat affected zone (HAZ)
of the welded joint, i.e. in the zone of residual stresses, heat treatment after welding significantly
expands the possibility of using carbon and low-alloy steels (see Figure 8.4.1) [10]. After heat
treatment, welding of any structural elements to a tank, vessel or pipeline shall be excluded.
Austenitic steels are much more resistant to ACC than ferritic-pearlitic steels. The main method
of dealing with ACC is heat treatment of welds.
Figure 8.4.1 – NACE Diagram to Determine Conditions for the Use of Carbon and LowAlloy Steels in Alkaline Solutions: I – no residual stress release (post weld heat treatment PWHT)
is required; II – residual stress release is required by means of PWHT; III – possible ACC of carbon
and low-alloy steels, stainless steels shall be used. See the exposure of stainless steel in Figure 2
in NACE SP 0403.

INTI R.00.1-2021
8.5 Sulfuric Acid Corrosion
The possibility of using metallic materials in solutions of sulfuric acid is determined by
passivation properties of these materials [10].
Sulfuric acid is very aggressive. Despite the fact that the acid is oxidizing, in its dilute
solutions the role of oxidizer is played by hydrogen ions formed during dissociation of the acid.
Due to the high hydrotation energy at a low concentration of the solution, SO42- ions become
surrounded by a hydrate shell and are not able to show their oxidizing ability. At a higher
concentration of sulfuric acid solution, it reacts with metals as an oxidizing agent, i.e., along with
the reduction of hydrogen ions sulfate ions are also reduced [10].
Sulfuric acid is a strong oxidizer, with a high concentration of acid easily passivating the
surface even of carbon and low-alloy steels. Passivation is possible only at low temperatures and
is associated with the formation of a dense layer of iron (II) sulfate on the steel surface, insoluble
in a concentrated solution of H2SO4. As temperature goes up, solubility of FeSO4 in sulfuric acid
increases and the passive state is disturbed [10].
An increase in the flow rate of the medium negatively affects protective properties of the
iron sulfate layer, which explains the accelerated destruction of the metal in the course of operation
[10].
Chemical composition of carbon steel has a very significant effect on its resistance to H2SO4
solutions. Increasing carbon content of steel from 0.19 to 0.84% increases corrosion rate by about
an order of magnitude. Sulfur and phosphorus usually reduce corrosion resistance of steel.
Manganese has little effect [10].
Austenitic chromium-nickel steel grades 08X18N10T, 12X18N10T, AISI 321,
X6CrNiTi18-10/1.4541 and austenitic-ferritic steel grades 08X22N6T are recommended for the
use in sulfuric acid solutions at very low concentrations (up to 0.1%) and low temperatures, or at
concentrations above 95% and temperatures up to 40°C, i.e. in conditions in which they retain a
passive state. Chromium-nickel-molybdenum steel grades 10X17H13M2T, 10X17H13M3T,
316Ti, X6CrNiMoTi17-12-2/1.4571 are applicable in a wider range of concentrations and
temperatures. Alloy grade 03XN28MDT has even wider application limits. Figure 13.5.1 shows
application zones of corrosion-resistant materials in sulfuric acid solutions [10]; NACE SP 0391
can also be used to select the material.
Stainless steels in sulfuric acid are subject to inter-crystalline corrosion (ICC). To reduce
probability of ICC, stainless steel grades with a reduced carbon content are used (for example,
03X18H11, AISI 304L, X2CrNi19-11/1.4306, etc.) and titanium-alloyed steel grades
(12X18H10T, 08X18H10T, AISI 321, X6CrNiTi18-10/1.4541). In the steel manufacturing
147
INTI R.00.1-2021
process, a stabilizing annealing is used (temperatures 900-950°C, holding time 3-5 hours).
Besides, metals and their welded joints designed to work in conditions that cause ICC shall meet
the requirement for resistance to ICC in accordance with GOST 6032-2017 [10].
Turbulent flows of sulfuric acid increase the rate of corrosion, including faster ICC
manifestations.

8.6 Glycol Solutions Corrosion
The nature and intensity of metal corrosion in glycol solutions depend on the nature of
glycol, its concentration in absorbents, the presence of oxygen in the system, temperature, and the
presence of salts in the absorbent solution [10].
148
INTI R.00.1-2021
Aggressiveness of glycols is most often associated with their ability to get oxidized by air
oxygen or self-oxidized with the formation of low-molecular organic acids, most aggressive of
which is formic acid. Glycol’s ability to get oxidized and the nature of acids formed therefrom
depend, under other different conditions, on the structure of the glycol molecule and its molecular
weight. At the same temperature and concentration of the solution, corrosion aggressiveness of
glycol in the ethylene glycol – triethylene glycol – diethylene glycol – tetraethylene glycol series
increases (see Figure 8.6.1). It is explained by the appearance of organic acids in the medium.
Acidity of the medium in the series also increases: in the presence of tetraethylene glycol, it reaches
its maximum. At a temperature of 130°C in a 95% solution of tetraethylene glycol, pH factor of
the medium drops to 2.9, whereas in the absence of this absorbent, pH=6.3 [10].
The corrosion situation is largely determined by operating temperature of the corrosive
medium. In concentrated glycol solutions (95–100%), the rate of corrosion monotonically
increases together with the temperature in both the liquid and vapor phase, regardless of the nature
of glycol. In relatively dilute solutions (10-90%), the dependence is extreme, with a maximum at
a temperature of 100°C (see Figure 8.6.2). This is explained by the fact that in concentrated
solutions, the corrosion process proceeds with a predominant hydrogen depolarization. The
cathodic process involves hydrogen ions formed as a result of dissociation of glycol self-oxidation
products on the metal surface following the acidic mechanism. In dilute solutions, the depolarizer
is not only hydrogen but oxygen as well, whose solubility in the medium is significantly reduced
at high temperatures both in the liquid phase and in the thin film of the electrolyte on the metal
surface in the vapor phase [10].

Since corrosion of metal is mainly associated with the formation of organic acids in the
working medium, inhibitors that can neutralize the resulting acids are introduced into the medium
to combat corrosion. For this purpose, such substances as alkanolamine solutions with the addition
of sodium salts of phosphoric and other weak acids can be used [10].

INTI R.00.1-2021
8.7
Corrosion Caused by Amine Solutions
Carbon steels.
In the case of carbon steel, both corrosion cracking and mass-loss corrosion must be taken
into account as follows:
- For corrosion cracking, not only the usual stress cracking in a sulfide-containing medium
(due to H2S) must be taken into account but also the well-known stress cracking in an
amine medium which is not directly related to the H2S content.
- For mass-loss corrosion, the actual corrosion rate and corrosion morphology at any
location are mostly the result of a “rivalry” between the corrosion behavior of the amine,
i.e. its ability to destroy unprotected steel, and the protective behavior of the iron sulfide
layer formed on the surface of the steel. In a situation where the protection is efficient,
the corrosion rate is negligible whatever the corrosion behavior is. On the other hand,
however, if the protection is damaged (e.g., because of high surface flow rates) or has
defects in it, the corrosion rate is determined by the corrosion behavior or the possible
influence of galvanic coupling in the case of localized corrosion.
Among the factors that can affect protective properties of anti-corrosion layers in amine
installations, these four are most significant:
1.
High flow rates are proven to be the main factor contributing to corrosion, with
significant erosion-corrosion processes occurring in a variety of installations.
2.
The type of amine is also a key factor contributing to corrosion. Primary amines, such
as monoethanolamine (MEA) and diglycolamine (DGA), are often reported to be most corrosive
whereas methyldiethanolamine (MDEA) is generally considered to be least corrosive due to its
much higher stability.
3.
There is also a discussion about whether high concentrations of amines increase
corrosion rates significantly or not. This effect is not fully apparent, especially considering the
type of amine.
4.
Other factors, such as pH or temperature, can also negatively affect protective properties
of anti-corrosion layers thus increasing possibility of corrosion.
The corrosion behavior of amine solutions mainly depends on the following three
parameters:
1.
The hydrogen index (pH): the lower the pH is, the more intense the corrosion behavior
will be. It is emphasized that although the pH of lean amines exceeds 10, the pH of fat amines in
the lower part of the absorber decreases to 6.5-7.5 depending on the content of CO2 and H2S, and
the total pressure.
152
INTI R.00.1-2021
2.
The content of “heat-resistant salts” (mainly salts of formic, acetic and oxalic acids).
These acid degradation products are known to form from aeration of amines along the production
cycle and their further thermal degradation at high temperatures. When the pH is relatively low,
some of these salts exist in the acid form (formic, acetic, and oxalic acids).
3.
The temperature, which promotes electrochemical reactions and, thereby, intensifies the
corrosion behavior of the media. In particular, overheating at the reboiler level is widely known as
one of the main causes of serious failures due to corrosion in amine installations caused by thermal
degradation of amines.
Stainless steels.
Despite the fact that formation of cracks in stainless steels due to stress corrosion and
pitting/crevice corrosion does occur in some instances, the experience of using “standard” stainless
steels is generally positive:
- AISI 410 steel grade, i.e. stainless steel with 13% of chromium, is often used for trays
and downpipes inside regenerators and absorbers. However, depending on amine fluid
intensity and, in particular, on the content of heat-resistant salts results of using this lowalloy stainless steel grade are variable. Practical experience here ranges from very good
performance to intense corrosion.
- AISI 304L and 316L steel grades, often used for internal cladding in areas where carbon
steels may suffer from erosion/corrosion, and for fabrication of heat exchangers and
reboiler pipes. Several cases are known when AISI 304 steel corroded under special
conditions, and AISI 316L steel corroded under extreme operating conditions [9]. But
usually corrosion performance of these steel grades is reported to be very high.
The good corrosion behavior of stainless steel grades is due to the following reasons:
1.
The amine fluid does not contain any strong oxidizing substances, as long as oxygen
ingress is properly prevented.
2.
The amine fluid has a strong buffering power (~4 mol/L) although the pH value itself
can be very small, so that the probability that the anode-cathode differentiation may cause pitting
and crevice corrosion is much less than, for example, in case of seawater.
3.
The quantity of chloride contained in the amine fluid is limited (at present, in the range
of 100-300 mg/L in most installations).

SELECTION AND REPLACEMENT OF STEEL FOR WELDED STEEL VESSELS
9.
SHEET STEEL
For comparison, the standards of the American Society of Mechanical Engineers (ASME)
for pressure vessels and boilers, Part IIA “Technical Specifications for Ferrous Metals” containing
General Technical Specifications for sheet steel materials (in particular, SA-6, SA-20, SA-480),
and requirements for products made of various steels, for example, for steel plates, thin sheets or
strips (in particular, SA-203, SA-240, SA-263, SA-264, SA-283, SA-353, SA-387, SA-516, SA537, SA-542, SA-553, SA-645) have been taken. Analogs or substitutes in accordance with the
EN standards are added to the considered steels listed in the Tables. When comparing the
standards, requirements for steel strips, rolled section and profiled products are not considered.
Steel sheets are rolled products of rectangular cross-section with a large width-to-thickness ratio,
produced mainly on sheet rolling mills and delivered in sheets and rolls.
The U.S. standards provide for a system of dividing the Technical Specifications into
General and Supplementary requirements, as well as group and individual products. Russian
standards, in particular, GOST 14637, GOST 5520, GOST 19281, GOST 5582, GOST 5632,
GOST 7350, GOST 10885, GOST R 58915 do not provide for such a system and contain specific
General and Supplementary technical requirements for a specific product, include references to
other standards containing requirements for chemical composition, grade and size tolerances,
control and testing methods, measuring instruments, sampling rules, labeling, packaging,
acceptance procedures, and acceptance documents.
The U.S. standards, in particular SA-203, SA-263, SA-264, SA-353, SA-387, SA-516, SA537, SA-542, SA-553, SA-645, contain the following reference to the standard with the General
and Supplementary requirements:
“The material supplied in accordance with these product specifications shall meet the A20/A20M
General Specifications. These requirements describe the methods and algorithms for conducting
initial tests and repeated tests, dimensional tolerances, allowable weight and quality deviations,
procedure to repair defects, labelling and handling procedures, etc. Also, the A20/A20M General
Specifications set out rules regarding purchase order information that shall be taken into account
when purchasing material in accordance with this Guide. The customer is responsible for the
completeness of the specified requirements that need to be met to place purchase order for the
material in accordance with these Specifications. Similar references to the SA-6 and SA-480
General Specifications are contained in the SA-283 and SA-240 standards, respectively.

Hg) or at normal pressure (for filling) designed for the use in process installations of the chemical,
petrochemical, oil refining, gas treatment, oil, gas and other industries, designed for strength, in
accordance with the requirements of GOST 34233.1-12, GOST 34283, is GOST 34347. It is
allowed to use other technical specifications to select materials when designing vessels if they do
not contradict the requirements of this standard and the technical regulations CU TR 010/2011 and
CU TR 032/2013.
Comparison of steel sheet products was carried out in four groups: carbon and low-alloy steels,
high-alloy steels, nickel cold-resistant steels, double-layer sheet products. Carbon and low-alloy
steels, in the context of this section, include the following: carbon, manganese-silicon, chromiummolybdenum, and chromium-molybdenum vanadium. The group of high-alloy steels, in accordance
with the study on sheet products, includes the following steels: corrosion-resistant chromium with a
chromium content of at least 13%, chromium-nickel, chromium-nickel-titanium, chromium-nickelmolybdenum-titanium, chromium-nickel-molybdenum and chromium-nickel heat resistant. Nickel
extremely cold-resistant steels are steels with a nickel content of 3-10% intended for the manufacture
of isothermal tanks for storage and transportation of cryogenic liquids. There is information about
the manufacture of pipelines and apparatus made of this type of steel abroad. Double-layer sheet
products include cladded corrosion-resistant sheets with a base layer of carbon or low-alloy steel and
a clad layer of corrosion-resistant steel. Sheet steels, when manufactured in accordance with
respective strength classes, are regulated by the following standards: GOST 17066, GOST 19281,
GOST 27772. The strength class characteristics are listed in Tables 9.2.2, 9.2.3, and 9.2.4.
Table 9.1 presents the results of a comparative analysis of the requirements for chemical
composition and mechanical properties of materials with the selection of Russian analogs or
possible substitutes for foreign steel grades, taking into account the requirements of GOST 34347.

Notes to Table 9.1:
* - Additional HIC test is required.
ASME SA-283 Grade C rolled structural steel sheets (General Specifications under ASME
SA-6) are generally used for the manufacture of non-pressure structures. As a substitute for the
ASME SA-283 grade C steel, St3sp of category 5 in accordance with GOST 14637 is usually used.
Not all Russian analogs and substitutes can be produced in accordance with interstate standards
(GOST). Many Russian metallurgical plants and plants of the former USSR countries produce sheet
products in accordance with technical specifications (TU) or organization standards (STO)
developed for Russian and commercial use. Often, this type of regulatory and technical
documentation is not available for public access, constitutes a trade secret or intellectual property,
and national and interstate standards with General and Supplementary Specifications for such steels
have not been developed.
Steel 20YuCh, resistant to hydrogen sulfide corrosion cracking, is a development of the
Bardin Central Research Institute of Ferrous Metallurgy and the All-Russia Research Institute of
Petroleum Machinery.
SA-537 Class 1 or Class 2 steel is practically not found in foreign projects related to the use
of petrochemical equipment.
A comparative analysis of the requirements for sheet rolled steel products made of steel
grades 10X2M1A-A and 15X2MFA-A was carried out in accordance with the non-updated
technical specifications of Izhorskiye Zavody PJSC. The industry standard for sheet products of
steel grades 10x2M1A-A and 15X2MFA-A is expected to be developed by the Chemical Industry
Machinery Association.
For SA-240 Type 316 steel, 03X17N14M3 steel is used as a substitute based on the practical
experience of application of these steels in the petrochemical industry.
Requirements for rolled steel sheets of grades 20X23N13, 0N3, 0N6B and 0N9 are not
provided in GOST 34347.
GOST 10885 mainly regulates combinations of steel grades, sizes and tolerances for them
for hot-rolled double-layer sheets made by batch rolling. There are no standardized requirements
for clad materials produced by electroslug build-up welding or explosion welding, but
manufacturers’ specifications are available.
SA-553 Type I, SA-353, X8Ni9/1.5662, X7Ni9/1.5663 EN 10028-4 steel grades are
analogues for 0N9, 0N9B (GOST R 5815), 0N9 (TU 14-105-846-2008) by the chemical
composition. They contain the same amount of the main alloying elements, such as nickel and a
slightly different amount of other elements.

INTI R.00.1-2021
SA-645 Type B, SA-841 Grade G, SA-553 Type III, SA-553 Type II steel grades can be
replaced by 0N6B steel grade according GOST R 58915 or TU 14-105-846-2008. 0N6B steel
grade is more suitable for replacing for lower nickel content limit SA-645 Type B steel, for upper
nickel content limit SA-553 Type II and SA-841 Grade G and SA-553 Type III for the middle
nickel content level.
SA-645 Type A and X12Ni5/1.5680 EN 10028-4 steel grades are analogues by the chemical
composition and there is no Russian analogue. 06Н3 steel grade can be used as a Russian analogue
for 12Ni14/1.5637 EN 10028-4 but 06N3 steel grade doesn`t manufacture in Russia.
06N3 (N) steel grade can be used to replace 12Ni14 grade, 06N3 (QT) and 0N6B (GOST R
58915 or TU 14-105-846-2008) steel grades can be used to replace steel X12Ni5 and 0N9B
(GOST R 58915) steel grade can be used to replace SA-645 Type A, X8Ni9 (NT640), X8Ni9
(QT640) steel grades and 0N9 (GOST R 58915 or TU 14-105-846-2008) can be used to replace
SA-645 Type B, SA-841 Grade G Class 9, SA-553 Type III, SA-553 Type II, SA-553 Type I, SA353, X8Ni9 (QT680) and X7Ni9/1.5663 EN 10028-4 steel grades If the effects of thermal
treatment and the level of mechanical properties will be considered in terms of strength and
ductility.
SA-841 Grade G Class 10 steel has a higher level of strength with the comparison to other
steel brands.
It should be noticed, that thermomechanical treatment depends on buyer`s demands and
modes and effects to the mechanical properties level for 0N6B and 0N9 steel grades, so these steel
grades can replace all expect foreign steel grades with the necessary licensors projects' strength
level, ductility (depends on heat treatment) and impact toughness level at corresponding negative
temperatures and the basic steel chemical elements.
P355GH steel is specified as an analog, but it is necessary to take into account the delivery
conditions for the product (heat treatment and a possible range) for correct selection of materials
and the steel grade should be chosen according to the corresponding parts of EN 10028 (possible
steel brands: P355GH, P355N, P355NH, P355NL1, P355NL2, P355M, P355ML1, P355ML2,
P355Q, P355QH, P355QL1, P355QL2). All steels according to EN standard should apply this
requirement.
Steel grades under the EN standards are given here for reference; data on cladded sheets for
these steel grades are not provided. Table 9.1 does not limit the list of steel grades. Another analog
or substitute may be used in accordance with the requirements of the design documentation if
mechanical and chemical characteristics of the analog are equal to or more favorable than
characteristics of the specified steel.

INTI R.00.1-2021
9.1 Comparison of Chemical Composition of Different Steel Grades
Comparison of chemical composition (melt analysis) of Russian and foreign grades of steel
groups 1, 2, 3 is given in Table 9.1.1. Comparison of extreme deviations in mass fractions of
chemical elements in analysis of finished products of Russian and foreign grades of steel groups
1, 2, 3 is given in Table 9.1.2.
Chemical composition of steel grades in accordance with Russian standards is mainly
determined by analysis of dip specimens from each melt, and deviations of mass fraction of
chemical elements in finished rolled steel products from the norms determined by the dip specimen
are duly regulated. Chemical composition of steel grades in accordance with the U.S. standards is
also determined by analyzing dip specimens of each melt. However, in accordance with the U.S.
standards, at the customer’ request chemical composition of the finished product can be analyzed
(Supplementary Requirement S2), and results of such analysis shall be recorded in the test report.
In accordance with Russian standards, analysis of chemical composition of finished products is
carried out at the manufacturer’s discretion or by agreement with the customer; often, data from
the melt quality certificate are copied to the sheet quality certificate. Also, in accordance with the
U.S. standards, at the customer’s request vacuum treatment of steel (Supplementary Requirement
S1) and deoxidation with carbon in vacuum (Supplementary Requirement S17) can be performed.
In Russian standards, meeting these requirements in production of steel products is usually left at
the manufacturer’s discretion in view of the steel melting process, which is an internal document
of the manufacturer.
In accordance with SA-20 (Supplementary Requirement S17), the steel shall be deoxidized
with carbon in vacuum (steel vacuum decarburization in the course of melting), with the maximum
silicon content at the time of vacuum deoxidation being 0.12%, and the content of deoxidizers
such as aluminum, zirconium and titanium shall be kept as low as possible to allow carbon
deoxidation. The test report shall indicate that the steel was deoxygenated with carbon in vacuum.
The minimum requirements for silicon content for the purpose of dip specimen test and product
test do not apply to carbon-deoxidized steel in vacuum.

Notes:
1. For chemical elements whose mass fraction in Table 2a has the upper limit and no lower limit, positive tolerances are used only.
2. The “±” sign means that the limit deviation for each of the elements in the finished roll of one steel melting can only be below the lower limit or only above the upper limit of the element mass fraction values
specified in this Table, but not both “plus” and “minus”.
3. The “–” sign means that the maximum deviations in the mass fraction of chemical elements in the finished product are not allowed.
Notes to Tables 9.1.1 and 9.1.2:
1) Comparison of the chemical composition of two-layer materials is not reasonable to show in the Table;
2) The class of a steel under the U.S. standards is not related to its chemical composition, so it is excluded from designation of the steel grade in the Table;
3) For Russian steel grades of austenitic class, unlike U.S. steel grades, no requirements are specified for the content of nitrogen, although it may be present in steel as a residual component;
170
INTI R.00.1-2021
4) Steel plates in accordance with the SA-353 and SA-553 standards differ only in terms of requirements for heat treatment modes; they are identical in chemical composition and mechanical properties. Analogs are
0H9 or X7Ni9 steels;
5) The tolerances for many steel grades are identical.
In the manufacture of sheet steel in accordance with strength classes, its chemical composition shall comply with Table 9.1.3.

Requirements for chemical composition of steel defined by melt analysis under GOST 27772 are presented in the Profiled Rolled steel products section of that standard.
9.2 Mechanical Characteristics
In Russian and in foreign standards, requirements for mechanical properties include requirements for tensile and requirements applicable depending on the standard used or as agreed: impact strength (impact bending)
tests and hardness measurements. The material provided for tests shall meet the requirements specified in the applicable product standards or specifications. Tests shall be made for the finished product that has passed all
the heat treatments required to achieve the required level of mechanical properties. Comparison of mechanical properties of sheet steel in the supply condition under foreign and Russian grades of steel groups 1, 2, 3 is given
in Table 9.2.1.
SA-6, SA-20 and SA-480 require that all tests for mechanical properties shall be carried out in accordance with the test methods described in A370. As provided in SA-6 and SA-20, the following rounding method
shall be used for the test results analysis procedure: the calculated value of the tensile strength and yield strength shall be rounded to the nearest integer value of 5 MPa, and the other values shall be rounded to the nearest
unit in the rightmost row of the number expressing the limit value, in accordance with the rounding method set out in ASTM E29. In accordance with Russian standards for sheet steel product, tests for mechanical properties
are carried out observing requirements of different standards for each test method. Mechanical properties as a function of temperature, for ASME steels, are specified in the ASME BPVC.II.D standard. For EN steels, these
properties are specified in corresponding standards that regulate General Specifications for steels.
In the manufacture of sheet steel in view of strength classes, mechanical properties shall correspond to Tables 9.2.2, 9.2.3 and 9.2.4.

9.3 Assortments and Size Ranges
A comparison of requirements for size parameters (thickness, width, length) of sheet
products (rolled plates, sheets and strips) in accordance with foreign and Russian standards is given
in Table 9.3.1. In accordance with the Russian standards, tolerances of dimensions and shape of
sheet steel products (for example, flatness deviation, nonsquareness, etc.) are determined as
prescribed in GOST 19903 for hot-rolled steel or GOST 19904 for cold-rolled steel unless
applicable standards or specifications for the product set up other requirements. In accordance with
the U.S. standards, the maximum deviations in size and shape of sheet steel products are
determined in accordance with General Technical Specifications SA-6, SA-20, SA-480. This
section does not limit the use of other applicable standards.
Replacement is acceptable provided that the wall thickness is greater than or equal to the
values specified in the design documentation. The proposed replacement shall not impair the
overall performance.

PIPE PRODUCTS
In this Section, analogs of pipe steels are analyzed. They were divided into two groups:
group 1 that includes carbon and alloy steels; group 2 that includes stainless steels. By type, the
products are divided into seamless pipes, welded pipes and pipeline parts (fittings).
Table 10.1 presents Russian steel grades in accordance with GOST and their foreign analogs
or substitutes in accordance with the EN and ASTM standards. Pipes are manufactured in
accordance with the specified steel standards.
Pipe steels are designated in view of their strength properties. The following classifications
are used in the industry:
- By strength classes in case of pipe products for pipelines in accordance with GOST 17380,
GOST 20295, GOST 31443, GOST 31447 and GOST 33228;
- By strength groups in case of pipe products for casing pipes, production tubing pipes and
drill pipes in accordance with GOST 632, GOST 633, GOST R 50278;
- By strength groups in case of pipe products for casing pipes, production tubing pipes and
drill pipes in accordance with API Spec 5L, API Spec 5CT, API Spec 5DP and harmonized
standards GOST ISO 3183, GOST ISO 31446, GOST ISO 32696.
Comparison of materials regulated by the above standards is given in Table 10.1. Designation of
the strength classes in the GOST, GOST R and TU standards: Strength class designated by letter
“K” (“KP”) and a number indicating the minimum allowed value of instantaneous strength in
kgf/mm2( for example, steel grade K60 is pipe steel with an instantaneous strength no less than 60
kgf/mm2), or a three-number designation that indicates the yield stress (KP245).

Currently, work is underway to introduce cryogenic steel grades 0N3, 0N6B, 0N9,
X7Ni9/1.5663, X12Ni5/1.5680, 12Ni14/1.5637, SA-333 Gr.3, SA-645 Gr.B, SA-333 Gr.8 for the
manufacture of vessels and pipelines instead of chromium-nickel steel grades. Russian
manufacturing plants have the capacity to produce welded pipes and vessels made of cryogenic
steels; welding materials for these steels are specified in Section 7.
Table 10.2 does not limit the list of steel grades. Another analog or substitute may be used
in accordance with the requirements of the design documentation provide that the mechanical and
chemical characteristics of the analog are equal to or better than the characteristics of the specified
steel.
This section does not limit the use of standards applicable for pipe products and is of a
recommendatory nature.

FORGINGS
Forging is a metallurgical billet for further machining made by the method of plastic
deformation of metals in order to make its shape and size similar to the shape and size of the future
finished item so that to minimize the cost of further machining of the item thanks to reduction of
time spent on the job and quantity of metal chips which ultimately results in lower production
costs. Depending on the method of forming, forgings are divided into drop forgings and press
forgings. In accordance with the type of cross-section, there are square, round, rectangular and
polygonal forgings.
This section provides examples of the most widespread Russian steel grades used for
forging, and the selection of appropriate foreign analogs (substitutes) in accordance with ASME
and EN (Table 11.1).
This section also lists the main standards, specifications and technical requirements in
accordance with which forgings are made. Mechanical properties of steels (Table 11.2.1), norms
of mechanical properties of various strength categories (Table 11.2.2), requirements for chemical
composition of steels (Tables 11.1.1 and 11.1.2), and groups of forgings by type of tests (Table
11.2) are also indicated.
Forgings shall be controlled:
- for compliance with chemical composition of the steel;
- for mechanical properties of forgings (tensile strength in accordance with GOST 1497;
tensile strength at T = 550°C in accordance with GOST 9651; impact strength in accordance with
GOST 9454);
- for macrostructure in accordance with GOST 10243;
- for contamination in accordance with GOST 1778;
- by ultrasonic methods in accordance with GOST 24507 (results shall meet the requirements
of the standards in accordance with which forgings are made).
The scope of control shall be in accordance with the standard used (GOST 8479; GOST
7829; GOST 7505; GOST 25054).
The quality and characteristics of the material shall be confirmed by the manufacturer’s
certificate and the mechanical properties test protocol.
This section does not limit the list of standards that regulate forgings, and is of a
recommendatory nature.

3.
It is allowed to determine the hardness of forgings of the group on specimens for
mechanical tests.
4.
Attribution of forgings to a particular group is performed by the customer; the group
number is indicated in the technical requirements on the drawing of the part.
5.
At the customer’s request, delivery of forgings shall be performed with additional
types of tests not provided for in this standard (check for flakes, the Bauman test, ultrasound and
periscopic control, residual stress test, yield strength test at operating temperatures, fracture
toughness test at operating temperatures and negative temperatures, macro- and microanalysis of
steel structure, bend test, grain size analysis, etc.). In this case, forgings also belong to one of the
groups: II, III, IV and V, in accordance with Table 7.1.
6.
The forgings quality group in accordance with results of ultrasonic tests is established
in accordance with GOST 24507.
7.
The type, volume, standards and methods of additional tests are specified in the forging
drawing or purchase order.
248
INTI R.00.1-2021
8.
Ingots, compressed billets (blooms), forged or rolled billets, and billets made in
continuous casting plants, and various types of rolled steel products can serve as the source
material for the manufacture of forgings.
9.
Forgings are made of carbon, low-alloy and alloy steels, and their chemical
composition shall meet the requirements of GOST 380, GOST 1050, GOST 19281, GOST 4543
and other applicable standards or specifications.
10. Dimensions of forgings shall take into account machining allowances, tolerances and
surplus material required by the technology for forgings produced by press forging in accordance
with GOST 7062, drop forging in accordance with GOST 7829, and hot die forging in accordance
with GOST 7505, and surplus material for specimens for control tests.
11. For forgings weighing more than 100 tons produced by press forging, it is allowed that
tolerances and surplus material is specified in normative and technical documentation for a specific
forging.
12. In accordance with mechanical properties of forgings delivered after the final heat
treatment, they are divided into strength categories. The strength categories, respective norms of
mechanical properties determined by tests of longitudinal specimens, and hardness norms are
specified in Table 7.2.2.
13. Hardness standards for forgings of groups II and III and the strength categories for
forgings of groups IV and V are established by agreement of the manufacturer with the customer.
The steel grade is determined by agreement of the manufacturer with the customer and indicated
on the drawing of the part and respective forging.
14. For forgings of group IV, it is allowed to determine their mechanical properties not
with hardness lower and upper limits but with hardness standards that are within the specified
strength categories. In this case, the hardness is an additional delivery characteristic.
15. For forgings of group IV, it is allowed that in case of a batch of up to 20 pieces their
mechanical properties are determined on the basis of one forging if the difference in hardness test
imprints for the entire batch does not exceed 0.30 mm for KP18-KP45 and 0.20 mm for KP50KP80.

STEEL APPLICATION TEMPERATURES
The minimum application temperatures for steels are determined based on the KCV impact
strength tests of steel specimens. In accordance with CU TR 032/2013, the material assumed for
pressure equipment shall have the required degree of plasticity; to this end, results of steel specimen
tests at the minimum design temperature with a KCV concentrator shall be no less than 27 J/cm2,
and elongation after rupture shall be at least 14%. For materials regulated by the ASME standards,
the application limits are set by the manufacturing code. As a rule, the materials are already identified
with their lower temperature limit, without additional testing. USC only applies to carbon steel
grades and low-alloy steel grades based on the thickness and the MDMT combination. ASME
BPVC.VIII.1, UCS-66 regulates the requirements that allow not performing impact tests at certain
temperatures for pressure equipment. In case of deviation from the norms, in order to permit the use
of steels at low temperatures, impact tests are mandatory. Tables 12.1, 12.2, and 12.3 present the
permissible operating parameters of materials in accordance with GOST 34347 and recommended
analogs.
For cryogenic steel grades with a nickel content of about 3% (0h3, SA-203 Gr. D, SA-333
Gr. 3, 12Ni14/1.5637), the recommended minimum application temperature is –110°C; for steel
grades with a nickel content of about 6% (0H6B, SA-645 Gr.B, X12Ni5/1.5680), the
recommended minimum application temperature is –140°C; for steel grades with a nickel content
of about 9% (0H9, SA-353, SA-553, SA-333 Gr. 8, X7Ni9/1.5663), the minimum application
temperature is –196°C. Due to the lack of data, the maximum application temperature of these
steels is not specified.

When selecting the test temperature for Russian-made materials, the permissible operating
parameters (minimum wall temperature and medium pressure) shall be taken into account in
accordance with Tables 12.1, 12.2, 12.3.
12.2 Elevated Temperature Tensile Testing
The maximum temperature under which a material can be operated is specified in the ASME
code. In this connection, elevated temperature tensile tests are only necessary if the intended use
is in the creep range.
Tensile tests at elevated temperatures are carried out in accordance with the requirements of
Method E21 at the request of the customer in which case the purchase order shall specify additional
S7 requirements for SA-20 which is applicable to the following materials: SA-516 Grade 60 or
Grade 70, SA-537 Class 1 or Class 2, SA-387 Grade 5 Class 1 or 2, Grade 11 Class 2 or Grade 12
Class 2, SA-387 Grade 22 Class 2, SA-542 Type D Class 4a, and S2 for materials in accordance
with SA-240 (Type 304L, 304, 321, 316L, 316, 316Ti, 347, Type 410 or 410S, Type 309S). These
imported materials and their Russian analogs shall be tested for tensile strength at an elevated
temperature that corresponds to operating temperature of the pressure vessel. Depending on the
steel grade, the following test temperatures are usually regulated by the licensors: +200°C,
+250°C, +300°C, +350°C, +400°C, +450°C, +475°C, +500°C, +550°C, +600°C, +610°C,

ROLLED STEEL FOR STRUCTURAL ELEMENTS
In this section, a comparison of analogs (substitutes) of rolled steel grades for structural
elements is given. Structural steels are designated in accordance with strength classes.
This section presents a table of Russian steel grades in accordance with GOST and their
foreign analogs in accordance with EN and ISO.
Shaped rolled steel products are manufactured in accordance with the standards listed below.
Chemical composition of steel grades, in comparison with analogs (substitutes), is presented
in Table 13.1.1.
Mechanical characteristics of steel grades, in comparison with analogs (substitutes), are
given in Tables 13.2.1 and 13.2.2.
The minimum operating temperature for steel grades intended for structural elements of
various groups is specified in SP 16.13330.2017 and determined by requirements for impact
strength testing on a sample with a V-shaped concentrator. When selecting a steel grade, the
minimum design temperature for structural elements is assumed to be the temperature of the
coldest day with a probability of 0.98 in accordance with SP 131.13330.2018.
This section does not limit the list of standards used for rolled steel products and is of a
recommendatory nature.

13.3 Assortments and Size Ranges
This section gives a comparison of the assortments and size ranges for taper flange I-beams,
square and round rolled items, channels, equal- and unequal-leg angles.
This section does not limit the use of other applicable standards.
The substitution is acceptable provided that the wall thickness is greater than or equal to the
values specified in the design documentation. The proposed substitution shall not impair the
overall performance.
