development of domestic and overseas customers, as well as to the growth

of the world economy and the creation of affluent societies, in pursuit of

potential steel products as industrial base raw materials.

In particular, our steel bars/wire rods are trusted by many customers from

home and abroad and are used in various fields such as automobiles,

construction, heavy industry, home electronics, and OA equipment.

We will continue to respect our customers’ diverse needs, making every

effort to develop new products or improve manufacturing processes, in

addition to handing down skills, through weight reduction of major parts by

using high-strength steel, promotion of process-saving or energy-saving

concepts with high quality processed steel materials, and creation of a

recycling society by using environmentally-friendly steel materials.

We look forward to being of service to you and appreciate your continued

support from now on.

High-quality craftsmanship technique and thorough quality assurance system①High 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.

②Complete 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.

③High dimensional accuracy/shaping State-of-the-art rolling mills/cooling beds have been adopted, providing excellent

performance in shaping/dimension/straightness.

④Control 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.

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.

Stable supply by multi-mill systems We have a plurality of iron sources and rolling lines all over Japan as well as a flexible

response capability towards supplies even in the event of risks such as supply shortages,

disasters, etc.

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

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.

Cold headed (forged) products

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.

Springs

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.

PWS (Parallel wire strand)

We manufacture various types of covered electrodes and wire rods for micro wires for gas shield welding and submerged-arc welding.

Materials for welding

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.

Wire rods for steel tire 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.

Saw wires

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.
