Aditya Stainless stands out as a top manufacturer and supplier of Stainless Steel 309 Pipe Fittings right in Kolkata, India. We specialize in creating durable, high-performance fittings that are perfect for high-temperature and corrosive settings. SS 309 is an austenitic chromium-nickel stainless steel, celebrated for its excellent oxidation resistance and thermal stability. Our pipe fittings are built to withstand tough industrial conditions and adhere to international standards like ASTM A403 and ASME B16.9. We provide a diverse selection of fittings, including elbows, tees, reducers, caps, and stub ends, widely used in chemical, petrochemical, and furnace applications.
Stainless Steel 309 Pipe Fittings are made up of 22–24% chromium and 12–15% nickel, with a low carbon content that enhances weldability. This alloy boasts a minimum tensile strength of 515 MPa and a yield strength of 205 MPa, ensuring remarkable mechanical stability even at high temperatures. The elevated levels of chromium and nickel in these fittings provide outstanding resistance to oxidation, scaling, and sulfidation. They retain their strength and corrosion resistance in environments reaching up to 1000°C (1832°F), making them a dependable choice for heat-intensive and corrosive service applications.
