SPECIFICATION FOR CHROMIUM AND CHROMIUMNICKEL STAINLESS STEEL PLATE, SHEET, AND STRIP
FOR PRESSURE VESSELS AND FOR
GENERAL APPLICATIONS
SA-240/SA-240M
(Identical with ASTM Specification A 240/A 240M-04)
1.
3.
General Requirements
3.1 The following requirements for orders for material
furnished under this specification shall conform to the
applicable requirements of the current edition of Specification A 480/A 480M.
Scope
1.1 This specification covers chromium, chromiumnickel, and chromium-manganese-nickel stainless steel
plate, sheet, and strip for pressure vessels and for general
applications.
--``,,,,,````,,``````,,,,``,,`-`-`,,`,,`,`,,`---
1.2 The values stated in either inch-pound units or SI
units are to be regarded separately as standard. The values
stated in each system are not exact equivalents; therefore,
each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
3.1.1 Definitions,
1.3 This specification is expressed in both inch-pound
and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material
shall be furnished in inch-pound units.
3.1.6 Heat treatment,
3.1.2 General requirements for delivery,
3.1.3 Ordering information,
3.1.4 Process,
3.1.5 Special tests,
3.1.7 Dimensions and permissible variations,
3.1.8 Workmanship, finish and appearance,
3.1.9 Number of tests/test methods,
3.1.10 Specimen preparation,

Yield strength shall be determined by the offset method at 0.2% in accordance with Test Methods and Definitions A 370. Unless otherwise
specified (see Specification A 480/A 480M, paragraph 4.1.11, Ordering Information), an alternative method of determining yield strength
may be based on total extension under load of 0.5%.
C
Either Brinell or Rockwell B Hardness is permissible.
D
Bend test are not required for chromium steels (ferritic or martensitic) thicker than 1 in. [25 mm] or for any austenitic or duplex (austenitic-ferritic) stainless steels regardless of thickness.
E
Elongation for thickness, less than 0.015 in. (0.38 mm) shall be 20% minimum, in 1 in. (25.4 mm).
F
Common name, not a trademark, widely used, not associated with any one producer.
G
Yield strength requirements shall not apply to material under 0.020 in. (0.50 mm) in thickness.
H
Not applicable for thickness under 0.010 in. (0.25 mm).
I
Type 201 is generally produced with a chemical composition balanced for rich side (Type 201-1) or lean side (Type 201-2) austenite stability depending on the properties required for specific applications.
J
Rockwell C scale.
K
For S32615, the grain size as determined in accordance with the Test Methods E 112, Comparison Method, Plate II, shall be No. 3 or
finer.
L
Naming system developed and applied by ASTM.
M
Prior to Specification A 240–89b, the tensile value for S32950 was 90 ksi.
N
S40900 (Type 409) has been replaced by S40910, S40920, and S40930. Unless otherwise specified in the ordering information, an order
specifying S40900 or Type 409 shall be satisfied by any one of S40910, S40920, or S40930 at the option of the seller. Material meeting
the requirements of S40910, S40920, or S40930, may at the option of the manufacturer be certified as S40900.
O
Material 0.050 in (1.27 mm) and under in thickness shall have a minimum elongation of 20%.

SUPPLEMENTARY REQUIREMENTS
A supplementary requirement shall apply only when specified in the purchase order.
on duplex stainless steels covered in both Specification A 240 and Test
Methods A 923 to be performed at the lower of the temperatures specified
by this supplementary requirement and Test Methods A 923 Method B,
with measurement of both lateral expansion and impact energy.
S1. Charpy Impact Testing of Plate
S1.1 Charpy impact tests shall be conducted in accordance with Test Methods and Definitions A 370.
S1.2 Number of Tests — One impact test (3 specimens)
shall be made from one plate per heat treatment lot in the
final heat treated condition.
S1.5 Acceptance Limit — Unless otherwise specified on
the purchase order, each of the three specimens tested shall
show a lateral expansion opposite the notch of not less
than 0.015 in. [0.38 mm].
S1.3 Orientation of Test Specimens — Unless specified
as transverse specimens (long axis of the specimen transverse to the final rolling direction, root of the notch perpendicular to the rolling face) on the purchase order, the
orientation of the specimens shall be longitudinal (long
axis of the specimen parallel to the final rolling direction,
root of the notch perpendicular to the rolling face). The
manufacturer is permitted to test transverse specimens provided that such tests meet the acceptance criteria applicable
to longitudinal specimens. Unless otherwise specified on
the purchase order, the specimens shall be taken so as to
include the mid-thickness of the product.
S1.6 Records — The recorded results shall include the
specimen orientation, specimen size, test temperature,
absorbed energy values (if required), and lateral expansion
opposite the notch.
S2. Materials for High-Temperature Service
S2.1 Unless an H grade has been ordered, this supplementary requirement shall be specified for ASME Code
applications for service above 1000°F [540°C].
S1.4 Test Temperature — The purchaser shall specify
the test temperature. The manufacturer is permitted to test
specimens at a temperature lower than that specified by
the purchaser, provided that such tests shall meet the
acceptance criteria applicable to specimens tested at the
specified temperature (see Note).
S2.2 The user is permitted to use an austenitic stainless
steel as the corresponding H grade when the material meets
all requirements of the H grade including chemistry,
annealing temperature, and grain size (see Section 6).
S2.3 The user is permitted to use an L grade austenitic
stainless steel for service above 1000°F [540°C], subject
to the applicable allowable stress table of the ASME Code,
when the material meets all requirements of this specification and the grain size is ASTM No. 7 or coarser as determined in accordance with Test Method E 112. The grain
size shall be reported on a Certified Test Report.
NOTE — Test Methods A 923, Method B, applicable to some duplex
(austenitic-ferritic) stainless steels as listed in Test Methods A 923, uses
a Charpy impact test for the purpose of determining the absence of
detrimental intermetallic phases. Method B specifies a test temperature
and acceptance criterion, expressed as impact energy, for each type of
steel covered. It may be economical for the Charpy impact tests performed
