Stainless Steel 309S Tubing is a specialized high-alloy austenitic stainless steel designed for use in high-temperature and oxidizing environments. Thanks to its rich chromium and nickel content, this tubing excels in resisting oxidation, scaling, and corrosion even at elevated temperatures. With its precise dimensional control and smooth surface finish, Stainless Steel 309S tubing ensures dependable performance in tough industrial settings where thermal stability and durability are crucial.
What sets Stainless Steel 309S apart is its higher levels of chromium and nickel compared to standard austenitic grades, which significantly boosts its heat and oxidation resistance. The low carbon content of the “S” grade minimizes the risk of carbide precipitation, enhancing its weldability. It boasts impressive tensile and yield strength, along with excellent ductility and toughness, all while maintaining mechanical stability under both continuous and cyclic high-temperature conditions.
