Louis Metals, a leading stainless steel supplier and manufacturer located in Houston, USA, proudly offers high-quality Stainless Steel 310S Rectangular Bars, specifically designed for high-temperature applications and exceptional corrosion resistance. The 310S variant is a low-carbon form of 310 stainless steel, making it perfect for welded projects that face oxidizing and carburizing environments. Our 310S rectangular bars are crafted to meet stringent ASTM/ASME standards and are frequently utilized in furnace components, heat treatment equipment, and chemical processing systems. At Louis Metals, we provide custom sizes and quick delivery, ensuring robust, oxidation-resistant solutions for industries that demand reliable performance under thermal and mechanical stress.
Stainless Steel 310S Rectangular Bars are made up of 24–26% chromium and 19–22% nickel, with a low carbon content (maximum 0.08%) that enhances weldability and minimizes carbide precipitation. This alloy boasts impressive high-temperature strength, with tensile strength ranging from 520–750 MPa and yield strength around 205 MPa. It also exhibits good creep resistance and maintains its structural integrity at temperatures up to 1100°C (2012°F). The Brinell hardness falls between 160–190 HB. 310S excels in oxidizing environments, retaining excellent ductility, corrosion resistance, and toughness even at both elevated and cryogenic temperatures.

Stainless Steel 310S Rectangular Bars find extensive use in high-temperature industrial settings due to their remarkable oxidation resistance and strength retention. Typical applications include furnace components, kilns, radiant tubes, burner tips, heat exchangers, thermal processing equipment, and flue gas systems. They are also essential in petrochemical and refinery operations where high heat and corrosive conditions are prevalent. Thanks to its low carbon content, 310S is particularly suited for welded structures that need to endure prolonged thermal exposure. Louis Metals is your go-to source for 310S rectangular bars, ensuring quality and reliability in every order.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
