Stainless Steel 420 is a high-carbon martensitic stainless steel consisting of about 12–14% Chromium and about 0.15% Carbon. This mix offers excellent hardness, wear resistance, and reasonable corrosion resistance. The material can be heat-treated to provide high tensile strength and excellent thermal stability. SS 420 has good machinability, excellent polishing characteristics, and excellent abrasion resistance, making it fit for precision applications. Its mechanical performance provides reliability in stressed, worn, and corrosive media environments, achieving an equilibrium between strength and corrosion resistance to provide long-term industrial performance.
