Better quality through
technical innovation

Thanks to many years of experience in steel-making, Yasugi Specialty Steel continues to produce high quality products.

Isotropy® steel is created to reduce the defects in general steel caused by its anisotropic (direction-dependent) mechanical properties, using advanced melting and forging technologies.
We produce isotropic tool steel with nearly identical properties in both longitudinal and horizontal directions.

Isotropy contributes to the stability and long-term working life of dies and molds.

Further refinement
of Isotropy® steel

We will continue to accommodate our tool steel to the various needs of our customers. However, the global market is always changing, requiring continuous advances in quality, stability, and life-span.

Yasugi Specialty Steel bases the technical ideas of isotropy around feedback from our customers, which drives further refining of our tool steel. Thanks to this cycle of feedback and development, we are creating diverse and innovative solutions for a wide range of products in many fields.

CAE Solution

The bridge between theory
and manufacturing

Yasugi Specialty Steel uses computer aided engineering (CAE) to develop new materials and manufacturing processes. Based on CAE, we aim to bridge the advanced theories of steel production and practical manufacturing processes to create the world’s finest steel.

CMAP® makes full use of CAE by building theoretical numerical models that address technical issues in manufacturing. These numerical models can reproduce real-world problems in the computer, and help us solve them.

Computer visualization of unseen phenomena and non-measurable physical properties enables us to create optimum design solutions for our customers.

Highly developed manufacturing

Recently, analysis and simulation technologies have become indispensable tools for process development.

Based on CAE, we employ CMAP to estimate working life-span, dimensional deviation caused by heat treatment, and properties, to design the composition of materials used for molding and forming tools.
Computer simulations can help decrease the number of experiments needed to finalize the design.

It is necessary that design, analysis, and simulation programs are applied in parallel to ensure efficient, high level development.

Wide range of functional coatings

The Tribec® coatings are based on original technology.
They are designed to meet the needs of many molding and forming tools, featuring high wear resistance, excellent lubrication properties, and distinguished thermal resistance.

Composed of multiple layers, the Tribec coatings offer a superior life-span and maximize the potential of tools.


Molding and forming tools have diverse functions, and various potential weak points. With Tribec coatings, based on investigation into the failure modes of these tools, the failure mechanism is fully understood and verified. No deterioration of coating properties or dimensional deviation is tolerated.

With Tribec coatings the mold surface can be polished and low-temperature deposition can be applied.
Customers often request these techniques for a better working life-span.

Reliable performance

When it comes to coating technology, today’s components need to maximize performance and reduce friction. In our diamond-like carbon (DLC) coatings, we apply conventional coating technology to create DLC coatings that provide outstanding hardness and adhesion.

Our original DLC coating process achieves a low level of impurities and inclusions at the coating interface.
Fewer impurities at the interface means a higher adhesion strength.

The result is a reliable performance DLC coating called L-Frex(TM). By reducing energy loss caused by friction, L-Frex is suitable for automobile and machine components, among many other applications.

Raising potential through flexibility

The hardness and structure of DLC coatings can be modified by controlling deposition parameters.
This enables us to optimize DLC coating properties for certain uses or operational environments.

Our experience is not limited to molding and forming tools. We also supply component materials for industrial equipment and machinery, including automobile components.

We make best use of our expertise and knowledge to meet the expectations of our customers, for example in creating new types of unique DLC coatings.
In the future, L-Frex will provide greater value by enabling an even more flexible approach.
