Stainless steel 310/310S Buttweld Fittings are made of 25% chromium and 20% nickel, providing excellent oxidation and corrosion resistance in hot environments The 310S grade has a low carbon content to increase weldability and reduce carbide precipitation. These fittings exhibit high tensile strength (~515 MPa), yield strength (~205 MPa), and elongation (~40%). The structures are stabilized up to 1100°C, making them ideal for low-heat applications. These durable and corrosion-resistant materials are commonly used in the furnace, heat exchanger and petrochemical industries.
