Louis Metals is a reliable Stainless Steel 321 Hex Bars and Rods manufacturer and supplier in Houston, USA, which provides excellent quality stainless steel products designed for high-temperature and corrosion-resistant applications. Precision-made and from prime raw materials, Louis Metals’ SS 321 hex bars and rods are perfect for those applications demanding exceptional weldability, resistance to intergranular corrosion, and resistance to structural deformation under thermal stress. With a hexagonal shape providing improved grip and resistance to torque, these rods and bars find extensive application in industries of aerospace, petrochemical, power generation, and fabrication that require critical heat and corrosion performance.
321 Hex Bars/Rods of Stainless Steel are titanium-stabilized austenitic stainless steels, with a composition of 17–19% Chromium, 9–12% Nickel, and Titanium that inhibits carbide precipitation during welding. This alloy provides tensile strength of 515–750 MPa and a yield strength of approximately 205 MPa. SS 321 has favorable mechanical and oxidation resistance properties in service temperatures up to 870°C. It is non-magnetic in the annealed state and provides excellent intergranular corrosion resistance, and it is used for welded structures and long-term high-temperature applications where strength and reliability are needed.
