Stainless Steel 310/310S Flanges are manufactured using high-quality austenitic stainless steel containing chromium and nickel, offering excellent high-temperature strength, oxidation resistance, and durability. These flanges perform reliably in elevated-temperature environments and provide excellent resistance to scaling, thermal cycling, and various corrosive conditions. Their good formability and weldability allow them to be fabricated into different shapes, sizes, and dimensions to meet specific industrial requirements. The low-carbon variant, SS 310S, is particularly beneficial for welded applications as it helps reduce carbide precipitation and provides improved resistance in the heat-affected zone.
In their annealed condition, Stainless Steel 310/310S Flanges offer excellent resistance to oxidation, scaling, and high-temperature corrosion, making them suitable for demanding industrial environments. They are widely used in furnaces, heat treatment equipment, petrochemical processing, power generation, and other high-temperature applications because of their thermal stability and durability. While both SS 310 and SS 310S have similar chemical compositions, SS 310S contains a lower carbon content, which makes it more suitable for welded applications by reducing the risk of carbide precipitation. With their excellent fabricability, strength, and resistance to thermal cycling, Stainless Steel 310/310S Flanges remain a dependable choice for high-temperature industrial applications.
Stainless Steel 310/310S Flanges are primarily composed of iron, chromium, and nickel, with controlled amounts of carbon, manganese, silicon, and other alloying elements. The high chromium content provides excellent resistance to oxidation, scaling, and corrosion at elevated temperatures, while nickel enhances strength, toughness, and overall durability. Grade 310S contains a lower carbon content than 310, helping to reduce the risk of carbide precipitation during welding and making it particularly suitable for welded components and high-temperature applications.
