Stainless steel material is a kind of material, with close to mirror brightness, hard and cold touch, belongs to the more avant-garde decorative materials, with excellent corrosion resistance, formability, compatibility and toughness and other series characteristics, used in heavy industry, light industry, daily goods industry and building decoration industry.
Stainless steel is referred to as stainless steel, it is composed of stainless steel and acid steel two parts, can resist atmospheric corrosion steel called stainless steel, and can resist the corrosion of chemical medium steel called acid steel. Generally speaking, chromium content Cr more than 12% steel has the characteristics of stainless steel, stainless steel according to the microstructure after heat treatment can be divided into five categories: ferritic stainless steel, martensitic stainless steel, austenitic stainless steel, austenitic - ferritic biphase stainless steel and precipitation hardened stainless steel.
