Stainless Steels

Surface treatment and maintenance are required to protect iron from its tendency to rust. From the need to prevent this loss to rust came the developments of rust-free steel and stainless steel. To prevent rust, at least 10.5 percent chromium is used to form a fine oxidation (passive) film on the surface of the steel. Nippon Yakin produces a variety of stainless steel products superior to conventional stainless steel. Features of these products include resistance to heat, grain boundary corrosion, stress corrosion cracking and weather as well as being highly formable, machinable, and strong with or without being magnetizable.
