Stainless Steel 420 is a high-carbon martensitic stainless steel that contains about 12–14% chromium and has low carbon content, allowing it to be heat treated for enhanced hardness. On the mechanical side, it boasts excellent tensile strength, high yield strength, good wear resistance, and moderate corrosion resistance. This alloy strikes a balance between toughness and superior hardness, making it ideal for components that face mechanical stress and moderately corrosive environments. Its unique combination of strength, wear resistance, and dimensional stability ensures reliable performance in precision engineering and industrial applications.
