Our pride in special steel
Special steel brings a lot to the table, including its abundance as a resource, theease of recycling it, and the diversity of its material properties.
The special steel products that we create have supported industrial andeconomic progress and have been a part of people s everyday lives.
Special steel has a variety of properties that make it useful as a corecomponent in automobiles, robots, and even in the medical sector, and once it has
fulﬁlled its purpose, it is recycled in the electric arc furnacesteelmaking process to be reborn again and again.
Special steel is an essential ingredient to realize a sustainable society.
As a manufacturer of special steel, with its inﬁnite potential, we will continue toforge ahead with our heads held high.

even harsh usage scenarios

Top market share in Japan
High reliability that supports Manufacturing
Bearings are used in the rotational structure of automobiles, industrial machinery,rail, wind turbines, and various other types of machines and equipment. These
bearings are made from bearing steel, which excels in hardness, wear resistance,
and fatigue strength. Sanyo Special Steel has spent many years working to
improve the quality of our bearing steel, establishing our own original steel
manufacturing and inspection techniques. Our bearings cleanliness, which
heavily determines the lifespan of a bearing, is simply unmatched in the industry.
Sanyo Special Steel will continue contributing to the development of industry in
the future by further improving the reliability of our steel.

Engineering Steel［Examples of applications］

Functionality that meets increasingly advanced needs
Engineering steel is a type of special steel with improved performance in terms of strength,
toughness (tenacity), fatigue strength, and hardenability. It is used in important components
of automobiles, construction machines, industrial machines, and more. Sanyo Special Steel has
developed engineering steel such as the ECOMAX® series, which oﬀers superior functionality
and high strength without the use of precious alloy elements. We serve a wide range of needs
for smaller, lighter, and more cost-conscious parts.

hidden potential fully pursued

High performance used in avariety of scenarios

Oﬀering world-leading quality

Special materials that are used in extremely harsh environments that
normal special steel could not endure (such as chemical and power
plants) are called Heat and corrosion resistance alloy . Sanyo Special
Steel uses these alloys to serve a wide variety of customer needs by
producing steels that oﬀer superior performance, such as throughnickel-based alloys that provide superior corrosion and heat resistance.

Gears

The world's highest level of quality.
Special steel is used in particularly important components ofautomobiles, industrial machinery, plants, and other equipment.
Moreover, the demand for special steel continues to evolve with thechanging times, including its use to improve the functionality ofﬁnished products and reduce its environmental impact, and for
applications in newly developed devices.
Drawing on our foundation of expertise in the production of highcleanliness steel, Sanyo Special Steel lives up to the trust andexpectations that our customers place in us, providing a stable supplyof steel crafted to respond to their changing needs.

Serving needs from a multilateral approach
As the pace of technological progress accelerates, customer needs are becoming
increasingly diverse and sophisticated. We look from the customer s perspective to
identify those qualities and characteristics that are the true key to progress and workon these to optimize our steel from its composition and structure through to
production. We are exploring the very limits of steel s potential.

Earning trust through sophisticatedevaluation and analytical techniques

When it comes to special steel, even slight diﬀerences in composition can impact thecharacteristics of the material. The progress of evaluation technology̶making the invisible visible
and the unknown known̶is the source of new knowledge and the basis for the trust placed in us.
