Stainless Steel 431 Square Bars and Rods belong to a martensitic stainless steel grade, recognized for their high strength, hardness, and moderate resistance to corrosion. Typically, their composition features 16–18% chromium, 0.15–0.25% carbon, along with trace amounts of nickel, manganese, and silicon. These bars and rods can be heat-treated to boost their hardness and wear resistance. In terms of mechanical properties, they showcase a tensile strength ranging from 850 to 1000 MPa, a yield strength of about 450 to 600 MPa, and a hardness between 200 and 300 HB. These characteristics make them perfect for components that demand toughness, durability, and dependable performance in moderately corrosive settings.
