Arakawa Stainless Kougyou Co., Ltd.

A specialist manufacturer of special steel materials able to handle materials which are difficult to cut or process.

We manufacture and sell products made of special steel materials. Currently we have a system that can provide materials as well as produce molds, conduct molding, cutting, sheet metal forming, and processing, and distribute those products in an integrated manner. We are proud of our ability to process materials which are difficult to work such as super Invar, Inconel, and Hastelloy. Super Invar (FN-36) is a low-expansion alloy with small thermal expansion coefficient near room temperature and is used for parts in artificial satellites, semiconductors, LNG storage systems, and vaporization equipment. We also handle ordinary materials.


Other presentation

[Company strength]
We are a group of specialist manufacturers handling various types of manufacturing under bulk contracts.
We can also reduce costs for transportation between businesses and manufacturing costs. Reliable group members can process materials for customers with high quality and quickly.

[Business description]
We started dealing with general materials and special materials upon our foundation. We are a stainless steel manufacturer providing our products to small, medium, and large manufacturers. Currently, we provide materials; produce molds; conduct molding, cutting, sheet metal forming, and processing; and distribute the products in an integrated manner (from trial production to mass production). With the advent of the composite era, we are always considering how best to meet the demands of the times and contribute to customer satisfaction.


[Strength of products/technologies]
As a manufacturer of special steel materials, we excel at processing difficult-to-cut materials such as Super Invar, Inconel, Hastelloy, magnesium, and titanium. Inconel 690 is a Ni-Cr-Mo alloy with tungsten added and is mainly used for chemical drug manufacturing equipment and radioactive waste treatment facilities. Super Invar (FN-36) is a low-expansion alloy with small thermal expansion coefficient near room temperature and is used for parts in artificial satellites, semiconductors, LNG storage systems, vaporization equipment, and other parts. Some are treated with gold plating.
