Stainless Steel 420 is a martensitic stainless steel that contains about 12–14% chromium and 0.15–0.40% carbon. It can be hardened through heat treatment, which results in exceptional strength and wear resistance. Typically, the tensile strength falls between 700 to 1000 MPa, offering good ductility and moderate corrosion resistance. SS 420 is known for its excellent polishability, making it ideal for applications that require sharp edges or fine finishes. While it may not be as corrosion-resistant as austenitic grades, it performs admirably in mild atmospheric and industrial settings when properly heat-treated and maintained
