310S Stainless steel pipes are a premium-grade, austenitic chromium-nickel stainless steel alloy specifically designed for extreme high-temperature service. As the low-carbon version of grade 310, 310S offers exceptional resistance to oxidation, carburization, and cyclic heating, making it the material of choice for demanding industrial applications. Our 310S pipes are manufactured to the highest international standards, ensuring reliability, durability, and outstanding performance in the most challenging environments.

Key Features & Advantages

• Exceptional High-Temperature Strength: 310S retains a high level of mechanical strength and does not readily soften at temperatures up to 1150°C (2100°F), ensuring structural integrity under thermal stress.

• Superior Oxidation Resistance: The high chromium (Cr) and nickel (Ni) content forms a stable, protective chromium-oxide layer on the surface, providing excellent resistance to scaling and spalling in oxidizing atmospheres.

• Excellent Carburization & Sulfidation Resistance: Performs reliably in corrosive atmospheres found in furnace environments, such as those containing carbon or sulfur compounds.

• Outstanding Creep Resistance: Demonstrates superior resistance to deformation under mechanical stress at elevated temperatures over prolonged periods.

• Low Carbon Content: The controlled low carbon content minimizes carbide precipitation during welding and exposure to high temperatures, reducing susceptibility to intergranular corrosion and ensuring better weldability.

• Good Formability and Weldability: Can be readily fabricated and welded using standard stainless steel techniques.
