With higher chromium content than 304 for better oxidation resistance, stainless steel 309 tubing is a high-temperature austenitic stainless steel alloy made up of roughly 23% chromium and 12% nickel. With a yield strength of about 205 MPa and a tensile strength of about 550 MPa, it provides exceptional mechanical strength. Even at high temperatures, the material offers good toughness and elongation. Applications involving extreme heat and corrosive conditions can benefit from SS 309’s exceptional resistance to oxidation, sulfidation, and carburisation, as well as its ability to maintain structural integrity in environments up to 1000°C.
