Corrosion resistance of various stainless steel springs

The corrosion resistance of various stainless steel springs is introduced
304 is a kind of universal stainless steel, which is widely used to make equipment and parts with good comprehensive performance (corrosion resistance and formability)
301 stainless steel spring presents obvious work hardening phenomenon during deformation, which is used in various occasions requiring higher strength
302 stainless steel is essentially a variant of 304 stainless steel with higher carbon content
302B is a kind of stainless steel with high silicon content and high oxidation resistance
303se and 303se are free cutting stainless steels containing sulfur and selenium respectively
303se stainless steel is also used to make parts requiring hot upsetting because of its good hot workability under such conditions
304L is a variety of 304 stainless steel spring with low carbon content, which is used in the occasion where welding is required. The lower carbon content makes the carbide precipitated in the heat affected zone near the weld to the minimum, and the precipitation of carbide may cause intergranular corrosion (welding corrosion) of stainless steel spring in some environments
