Stainless Steel 431 is a martensitic stainless steel alloy containing about 15–17% chromium and 1.25–2.5% nickel, which gives it impressive strength and moderate corrosion resistance. It can be heat-treated to achieve outstanding mechanical properties, boasting a tensile strength of around 850–1000 MPa and a yield strength exceeding 600 MPa. SS 431 also offers good toughness, hardness, and machinability. Its corrosion resistance outshines that of other martensitic grades, particularly in mildly corrosive environments, making it an excellent choice for components that need both high strength and resistance to wear, stress, and oxidation.
