Small amounts of manganese, silicon, and phosphorus are present in stainless steel 309S pipes, which also contain reduced carbon (maximum 0.08%), 12–15% nickel, and 22–24% chromium. Weldability is improved and the chance of sensitisation during high-temperature welding is reduced due to the low carbon content. SS 309S has a yield strength of about 205 MPa and a tensile strength of 515–750 MPa. It offers good creep strength, thermal stability, and outstanding oxidation resistance up to 980°C (1800°F). The alloy is appropriate for applications needing both heat and corrosion resistance because it maintains its toughness at high temperatures.
