Research and Development

We are challenging to develop new alloys, investigate and test based on accumulated Know How, data and activated extraordinary original idea. These activities are supported by sophisticated equipment such as high frequency induction melting furnace, thermal expansion measuring instrument, SEM etc. to cope with wide customer needs. Our products are widely used by cutting edge industries and getting high reputation by cope with customer’s special requirement with most suitable alloy which has environmental friendly component. We will further vitalize our development our of custom-made alloy to customer by making “The Best One for Customer” only available by us.

R&D exhibition room

We have just reformed our R&D center in our Saitama HQ. The meeting room and exhibition hall is located in 2nd floor. We are looking forward see you at this meeting room.

R&D accomplishmentTargeting to develop “Only one” special alloy steel which cannot be achieved just only JIS.

Control of CTE (Coefficient Thermal Expansion)

Invariable alloy is mainly used for those application which require low thermal expansion however sometimes just low thermal expansion is not enough for customer’s need. If the CTE(Coefficient Thermal Expansion) between invar and other parts combined, expected performance might not be obtained. As one of examples, when we had request to develop special alloy having the same CTE with special ceramics, we could make it by controlling CTE by adding some element to original alloy. Required CTE can be materialized by 1ppm each to make good match with other parts.

Prolonged life of heat and wear resistant tool at harsh environment

Piercer plug used for manufacturing seamless pipe of stainless steel, heat and wear resistant tool for , sintering plant of steel works, glass wool and biomass boiler are used at harsh environmental and challenges resist to such as wear, burn in, crack, deformation, oxidation and corrosion are required. Longer life of tools and parts for hot work have been attained by the best combination of alloy designing, heat treatment, surface coating. Especially for piercing plugs for seamless pipe and nozzles for biomass boiler of power generation, significant improvement has been achieved.
