Isis Metals, a reputable manufacturer and supplier located in Manila, Philippines, specializes in high-quality Stainless Steel 431 Square Bars and Rods. These products are celebrated for their exceptional strength, toughness, and resistance to corrosion. Crafted with precision and in line with international quality standards, they’re perfect for mechanical, structural, and marine applications. Stainless Steel 431 strikes a great balance between hardness and corrosion resistance, making it ideal for environments that face stress and moisture. Isis Metals guarantees precise dimensions, a superior surface finish, and consistent performance, providing reliable stainless steel products designed for demanding industrial and engineering needs.
Stainless Steel 431 Square Bars and Rods are martensitic stainless steels made up of chromium (15–17%), nickel (1.25–2.50%), and carbon (≤0.20%), along with trace amounts of manganese, silicon, and sulfur. This unique blend gives them impressive mechanical strength, toughness, and moderate resistance to corrosion. The alloy boasts a tensile strength ranging from 850 to 1000 MPa and shows good hardness after heat treatment. SS 431 also excels in oxidation resistance and fatigue strength, along with good machinability and polishability, making it a great choice for precision engineering and mechanical applications that operate under high stress and corrosive conditions.
