Characteristics of the bars and wire Rods of
1
NIPPON STEEL AND SUMITOMO METAL
High-quality craftsmanship technique and thorough quality
assurance system
① High purity/robust & uniform interior quality
High purity has been made possible using carefully selected raw materials, through the
integrated process of manufacturing from blast furnace to converter furnace.
Moreover, We aim to control the composition of non-metallic inclusions, lower the number
of harmful inclusions, and control segregation, through our high-performance refinery
processing facilities and continuous casting facilities, together with our advanced operating
technology and know-how.
② Complete assurance of the quality of surface and interior products
We assure the quality of surface and interior products, suitable for your purposes, through
thorough process control from steel making to the rolling process, by conducting magnetic
particle inspections, eddy current examinations, in addition to using state-of-the-art
inspection equipment such as supersonic detectors.
③ High dimensional accuracy/shaping
State-of-the-art rolling mills/cooling beds have been adopted, providing excellent
performance in shaping/dimension/straightness.
④ Control of metallographic structure
Metal structure control, suitable for the processing method or intended purpose, has been
made possible by our variety of controlled cooling and heat treatment facilities.

Plentiful product menu
In order to respond to diversifying needs/upgrading in various fields, the development of
new products and improvement of various properties is proactively implemented, creating
plentiful steel types/sizes for customers.
3
The ability to suggest solutions which combine steel materials
and the construction method
For the effective use of steel materials, we suggest solutions from aspects of both the steel
materials and the construction method by making excellent use of our collective strength, and
will strive to solve problems together with our customers.

Examples of applied parts
Automobile parts
Automobiles made in Japan are well-known as being No.1 in the world in terms of
quality and performance. Our products have shared in the support of this successful
technology. We have always been the leader in the technical development field with
regard to keeping vehicles weight down or the development of steel bars in which
the manufacturing process can be omitted, or environmentally friendly steel bars
such as lead-free bars, etc. We are capable of providing our customers with
appropriate suggestions, selecting from our diversified product menu, suitable for the
shape of the parts, function, manufacturing method, etc. of your intended purpose.

Application examples
Cold headed (forged) products
Wire rods for cold headed (forged) products have been widely
used because they can be manufactured into relatively simple
shapes such as bolts and rollers with high accuracy and high
efficiency. In recent years, products of more complicated shapes
have been used by combining extrusion, cutting, etc. with faster
processing speeds, causing the processing conditions to become
exceptionally severe for materials. Consequently, wire rods for cold
heading require excellent processing ability and stable product
quality. In other words:
(1) They must be homogeneous and have excellent deformability.
(2) They must have minimal processing load and the required
strength/hardness as an end product must be obtainable.
(3) They must not have surface defects or inclusion, which may
result in processing cracks, etc.
We manufacture CHQ wire rods of various types of steel that meet
such demands, under strict quality control, which have been
appreciated by many of our domestic and overseas customers.
Furthermore, developing new products such as various wire rods
without heat-treatment (SCS and NHF) has contributed to the
lowering costs for our customers.
Wire rods for steel tire cords
Saw wires
Steel radial tires are excellent in safety and are very economical,
making them very popular. We have received high acclaim both
domestically and overseas, as one of the most reliable makers of
wire rods for steel cords.
Saw wires are high strength superfine wires with a wire diameter of
approx. 120 microns, and silicon wafers for solar power generation
are used when cutting semiconductors. The wire rods we
manufacture for saw wires reduce the inclusion to the utmost limit
at which snapping may be caused when wire drawing or during
the cutting process. Our products are highly trusted and
appreciated both domestically and overseas.

Springs
Free-cutting steel has been widely adopted to improve the efficiency
of our cutting process. We have a wide range of free-cutting steel
for various purposes, such as sulfur type, sulfur compound type,
and steel type for mechanical structure. Furthermore, we have
developed and put into practical use lead-free steel that maintains
the efficiency of cutting and processing without using lead.
In particular, our prompt establishment of application technologies
for continuous casting in order to obtain homogeneity and stable
cutting has been very well received.
Springs are one of the representative uses of high carbon steel
wire rods. Our wire rods for springs are used for furniture springs,
mechanical springs, suspension springs for automobiles, and
furthermore, for valve springs which require top product quality.
Our products are highly evaluated and appreciated.
PWS (Parallel wire strand)
Materials for welding
Galvanized steel wires are used as cables for suspension bridges.
Our high-strength piano wires are used as the base metal for large
bridges with center spans of 2,000m or longer, including the
Akashi Strait Bridge.
We manufacture various types of covered electrodes and wire rods
for micro wires for gas shield welding and submerged-arc welding.
