Definition: Steel containing more than 12% chromium and resistant to chemical attack.

Principle: Stainless steel does not rust, but not easy to rust. The principle is that by the addition of chromium element, a dense layer of chromium oxide is formed on the surface of the steel, which can effectively block the re-contact between the steel and the air, so that the oxygen in the air cannot enter the steel, so as to prevent the steel from forming. rust effect.

Classification: China National Standard (CNS), Japanese Industrial Standard (JIS) and American Iron and Steel Institute (AISI) use three digits to represent different stainless steels, and are widely cited by industry offices, of which 200 series are chromium-nickel-manganese series Austenitic stainless steel, 300 series is chromium-nickel series austenitic stainless steel, 400 series chrome stainless steel (commonly known as stainless iron), including martensite and ferrite. In addition, there are also classifications by composition, magnetic permeability, heat treatment hardening and steel grade number.
