Their state-of-the-art production capabilities and rigorous quality control processes have established them as a preferred supplier in both domestic and international markets.
Stainless Steel 310S Bars and Rods are low-carbon variants of 310 stainless steel, containing about 24–26% chromium, 19–22% nickel, and a maximum carbon content of 0.08%. This specific composition significantly boosts their resistance to oxidation, sulfidation, and carburization at elevated temperatures. The material boasts a tensile strength of around 520 MPa, a yield strength of 205 MPa, and excellent creep resistance. Thanks to their lower carbon content, these bars and rods are easier to weld while still maintaining their structural integrity under high thermal stress and in harsh corrosive environments.

Stainless Steel 310S is designed with high chromium and nickel content, providing excellent resistance to oxidation and thermal stress, making it ideal for use in furnaces, boilers, and heat exchangers.
Stainless Steel 310S has a lower carbon content, which reduces carbide precipitation during welding, enhancing corrosion resistance and weldability without compromising heat resistance.
Industries such as petrochemical, power generation, and chemical processing use these bars and rods for applications like radiant tubes, kilns, and high-temperature structural supports.
Industries that require high-temperature strength and oxidation resistance widely utilize Stainless Steel 310S Bars and Rods. You’ll often find them in furnace parts, heat exchangers, burners, kiln liners, thermal processing equipment, and incinerators. They also play a crucial role in oil refining, chemical processing plants, and power generation units, proving their reliability in extreme conditions. Their corrosion resistance in mildly carburizing and oxidizing environments makes them a great fit for food processing equipment and steam boilers. With their excellent formability and weldability, 310S bars and rods are a trustworthy choice for structural and mechanical applications in high-heat industrial operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
