Classification of stainless steel

According to the organization structure at room temperature, there are martensitic, austenitic, ferritic and duplex stainless steels.

According to chemical composition, it is divided into two major systems: chromium stainless steel and chromium nickel stainless steel.

According to use, there are nitric acid resistant stainless steel, sulfuric acid resistant stainless steel, seawater resistant stainless steel, etc.

According to corrosion resistance type, it is divided into pitting corrosion resistant stainless steel, stress corrosion resistant stainless steel, intergranular corrosion resistant stainless steel, etc.

According to the functional characteristics, it can be divided into non-magnetic stainless steel, free-cutting stainless steel, low-temperature stainless steel, high-strength stainless steel, etc.

Due to its excellent corrosion resistance, formability, compatibility and toughness in a wide temperature range, stainless steel has been widely used in heavy industry, light industry, daily necessities industry and building decoration industry.
