About 15–17% chromium, 1.25–2.50% nickel, and 0.12–0.20% carbon make up the martensitic stainless steel alloy known as Stainless Steel 431, which also contains trace amounts of silicon and manganese. It provides good hardness, moderate corrosion resistance, and high tensile strength (up to 850 MPa). 431 has outstanding toughness and fatigue resistance following the right heat treatment. Compared to other martensitic grades, it is more machinable, which makes it appropriate for precision parts. It is a versatile material for demanding engineering applications because of its balance of corrosion resistance and mechanical strength.
