Corrosion resistant stainless steel spring

Stainless steel spring with corrosion resistance 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 variety of 304 stainless steel with higher carbon content, which can obtain higher strength by cold rolling.
302B is a kind of stainless steel with high silicon content, which has high oxidation resistance at high temperature.
303se and 303se are free cutting stainless steels containing sulfur and selenium, respectively. They are used in situations where easy cutting and high gloss are required.
303se stainless steel is also used to make machine parts requiring hot upsetting because it has good hot workability under such conditions.
304L is a variant 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 a minimum, and the precipitation of carbide may cause intergranular corrosion (welding erosion) of stainless steel spring in some environments.
