Stainless Steel 310S / 310H Pipe Fittings
Stainless Steel 310S / 310H Pipe Fittings are designed for high-temperature and corrosive service environments. With high chromium and nickel content, these fittings offer excellent resistance to oxidation, scaling, and sulfidation up to 1150°C. Grade 310S, with its low carbon content, ensures superior weldability, while grade 310H, with higher carbon, provides enhanced creep strength and durability. Available in elbows, tees, reducers, caps, and custom fittings, all products meet ASTM A403 / ASME SA403 standards and are widely used in furnaces, boilers, petrochemical plants, and power generation industries.
