309S Stainless Steel Sheet Manufacturer in China
309S stainless steel sheet is a type of austenitic stainless steel that can be cold rolled or hot rolled. It offers easy fabrication, welding, and stamping capabilities, but it cannot be hardened through heat treatment. At Tuolian, we provide customized services to cater to different sizes and various grades, ensuring customer satisfaction.
309S Stainless Steel Sheet Applications
309S stainless steel sheet finds extensive use in high-temperature applications. It is commonly employed in furnace equipment, annealing boxes, thermowells, heat exchangers, heating elements, aircraft and jet engine parts, and auto exhaust parts. It is even utilized in the production of annealing boxes, oven linings, baffle plates, quenching pots for salt, valves, and certain fittings.
309S Stainless Steel Sheet Properties
Due to its higher nickel and chromium levels, 309S stainless steel sheet has excellent corrosion, oxidation and heat resistance up to 1830° F. What’s more, our 309S stainless steel sheet is also equipped with high tensile strength.

The main difference lies in the carbon content. 309 stainless steel has a higher carbon content (up to 0.20%), while 309S stainless steel has a lower carbon content (up to 0.08%). This lower carbon content in 309S provides improved weldability and resistance to intergranular corrosion compared to 309 stainless steel.
