Stainless Steel 310 Seamless Tubes are heat-resistant austenitic stainless steel tubes manufactured without a welded joint for applications exposed to elevated temperatures and demanding thermal conditions. Grade 310, identified by UNS S31000, combines high chromium and nickel levels to provide strong oxidation resistance along with dependable mechanical performance.
The alloy's elevated chromium content helps protect the tube surface against oxidation and scaling, while nickel supports structural stability during high-temperature exposure. Stainless Steel 310 also offers good toughness, corrosion resistance and resistance to carburizing environments, making it suitable for specialized thermal-processing equipment.
Stainless Steel 310 Seamless Tubes are available to applicable ASTM and ASME specifications, with ASTM A213 and ASME SA213 commonly used for seamless austenitic stainless steel tubing intended for boiler, superheater and heat-exchanger service. Tubes can be supplied in different outside diameters, wall thicknesses, schedules, lengths and surface finishes.
These tubes are commonly selected for furnace components, heat-treatment equipment, petrochemical units, refinery systems, power-generation equipment, heat exchangers and high-temperature industrial processing. Their combination of heat resistance and seamless construction makes them suitable for equipment operating under severe thermal conditions.
