Product Description
309/309S Stainless Steel Pipe Overview
309 and 309S are austenitic chromium-nickel stainless steels specifically engineered for high-temperature applications. These alloys deliver exceptional corrosion resistance, superior oxidation resistance, and excellent heat resistance while maintaining strong mechanical properties at both room and elevated temperatures. The primary distinction between 309 and 309S is carbon content, with 309S featuring reduced carbon to minimize carbide precipitation and enhance weldability.
