Stainless Steel 309S fittings in pipe form consist of about 22–24% chromium and 12–15% nickel, with minimal carbon content to enhance weldability and prevent carbide precipitation upon welding. The fittings have a good tensile strength of about 515 MPa and good mechanical properties at high temperatures, up to 1000°C. Their content gives them excellent resistance to oxidation and fair corrosion, making them ideal for use where heat and chemical exposure are involved but structural efficiency is maintained.
