Research and Development

We work on various research and development such as high materials the special shape product.

Development of high corrosion resistance materials

 Appearance of corrosion test piece(ASTM G48-method F 60℃)

Normal stainless steel SUS316L

Development two-phase stainless steel

When the environment becomes severe, stainless steel also rusts. Even such environment has developed the material for which it's difficult to rust.
