420J1 steel is a martensitic stainless steel, mainly used for mechanical processing. It has better cost performance than normal stainless steel, so it has been more widely used when corrosion resistance is not required. After quenching, 420J1 can obtain better mechanical properties, has better processability, and has a martensite structure.
