Stainless Steel 309S pipe refers to a type of pipe made from stainless steel grade 309S. Stainless steel 309S is an austenitic chromium-nickel stainless steel often used in high-temperature applications. It offers good corrosion resistance, high-temperature strength, and oxidation resistance. The "S" in 309S indicates that it is a low-carbon version of 309 stainless steel. It helps minimize carbide precipitation during welding, making it suitable for welding applications without the risk of intergranular corrosion.
