301 stainless steel shows obvious work-hardening phenomenon during deformation, and is used in various occasions requiring high strength.
302 stainless steel is essentially a variant of 304 stainless steel with higher carbon content. It can obtain higher strength through cold rolling.
302B is a stainless steel with high silicon content, which has high resistance to high-temperature oxidation.
303 and 303Se are free-cutting stainless steels containing sulfur and selenium respectively, which are mainly used for occasions requiring easy cutting and high apparent brightness.
303Se stainless steel is also used to make parts requiring hot upsetting, because under such conditions, this stainless steel has good hot workability.
304 is a kind of universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive performance (corrosion resistance and formability).
304L is a variant of 304 stainless steel with low carbon content, which is used for occasions requiring welding. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, and the precipitation of carbides may cause intergranular corrosion (welding corrosion) of stainless steel in some environments.
304N is a kind of stainless steel containing nitrogen. The purpose of adding nitrogen is to improve the strength of the steel.
