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.

Largest Stainless Steel 310 / 310S Buttweld Fittings Supplier in Chennai, India
Stainless Steel 310 / 310S Buttweld Fittings contain mainly chromium (24–26%) and nickel (19–22%), with 310S having a lower amount of carbon content (≤0.08%) than 310 (≤0.25%), which improves weldability and minimizes the risk of sensitization. They have superior mechanical properties, such as tensile strength of approximately 515 MPa and yield strength of 205 MPa, accompanied by high creep resistance. Their high nickel and chromium content offer better oxidation and corrosion resistance, even in carburizing atmospheres, and are ideal for continuous exposure to high temperatures up to 1100°C.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
