How to improve the hardness of 304 stainless steel
Jul 10, 2022
304 stainless steel can only be strengthened by work hardening.
If you do not want to use 304 material, need to choose after cold forging or cold drawing 304 stainless steel bar as blank, the general deformation is greater than 75% hardness can reach Hv480 (HRC48.1), because of the different material composition of cold deformation corresponding to the hardening effect will be somewhat different. Martensitic stainless steels such as 420 can be hardened by heat treatment and are relatively easy to achieve.
304 is a universal stainless steel, which is widely used in the manufacture of equipment and parts requiring good comprehensive properties (corrosion resistance and formability). To maintain the corrosion resistance inherent in stainless steel, the steel must contain at least 18% chromium and at least 8% nickel. 3
