Stainless Steel 310, 310S, and 310H Pipes & Tubes are premium austenitic stainless steels supplied by Neonox Overseas, known for their exceptional resistance to high-temperature oxidation and superior mechanical properties. These grades are widely recognized for their outstanding strength and ability to withstand aggressive environments where conventional stainless steels fail. Due to their high chromium (24–26%) and nickel (19–22%) content, SS 310/310S/310H Pipes & Tubes offer excellent resistance to oxidation, scaling, and carburization, even at elevated temperatures up to 1100°C in continuous service and 1035°C in intermittent service.
Stainless Steel 310 Pipes & Tubes are considered the standard grade with good weldability, formability, and corrosion resistance, making them suitable for general high-temperature applications. Stainless Steel 310S is the low-carbon variant that minimizes carbide precipitation during welding and is highly resistant to sensitization and intergranular corrosion. It is particularly useful in applications involving continuous heating and cooling cycles. Stainless Steel 310H contains a higher carbon content, which enhances its creep resistance, tensile strength, and stress rupture properties, making it ideal for pressure vessels, boilers, and equipment subjected to long-term exposure to high temperatures.
At Neonox Overseas, we supply SS 310/310S/310H Pipes & Tubes in a wide range of types, including Seamless Pipes, Welded Pipes, ERW Pipes, Fabricated Pipes, and Mechanical Tubes. These are manufactured according to international standards such as ASTM A312, ASTM A213, ASTM A269, ASTM A249, and ASME SA312. They are available in various sizes, ranging from 6 mm to 610 mm outer diameter, with wall thicknesses from 0.5 mm to 50 mm, and lengths up to 12 meters, with custom cut-to-size options available.
These pipes and tubes are widely used in petrochemical plants, power generation, heat exchangers, furnaces, cement industries, refineries, food processing, and marine applications. Their superior oxidation resistance makes them suitable for furnace parts, radiant tubes, kilns, burners, and other high-temperature industrial equipment. In cryogenic applications, SS 310S is often preferred due to its excellent toughness at low temperatures, while SS 310H is chosen for its high strength at elevated temperatures.
In addition to excellent corrosion and oxidation resistance, SS 310/310S/310H Pipes & Tubes exhibit a tensile strength of 515 MPa minimum, yield strength of 205 MPa minimum, elongation of 40%, and Brinell hardness of 217 max. They are also easily fabricated and welded using conventional welding methods, ensuring high performance and durability in diverse industries.
By choosing Neonox Overseas, clients receive not only premium-quality Stainless Steel 310/310S/310H Pipes & Tubes but also the assurance of timely delivery, international quality standards, and reliable after-sales support. With an extensive inventory and a strong global network, Neonox Overseas stands as a trusted partner for industries requiring high-performance stainless steel solutions.
