309/309S Stainless Steel Pipe

309 and 309S are austenitic chromium-nickel stainless steels that are typically used for higher temperature applications. Due to its high chromium and nickel content, 309 and 309S alloys have a high degree of corrosion resistance, excellent oxidation resistance and excellent heat resistance, while providing good strength at room temperature and high temperature. The only significant difference between 309 and 309S is the carbon content. The 309S alloy has less carbon, which minimizes carbide precipitation and improves weldability.
