It can be used to make spring leaf, elastic spring, etc. At present, among the five major types of stainless steels that have been developed and applied in the world, only austenitic stainless steels are basically non-magnetic (or weakly magnetic after processing), while ferritic stainless steels, duplex stainless steels, Martensitic stainless steel, and precipitation hardening stainless steels are all magnetic.
