Stainless Steel 309S Pipes are primarily made up of high chromium (around 22–24%) and nickel (12–15%) with a low carbon content, which ensures exceptional oxidation and corrosion resistance even at elevated temperatures. This alloy boasts impressive mechanical properties, including good tensile strength, high creep resistance, and structural stability under thermal stress. These pipes are designed to resist scaling, thermal fatigue, and sulfidation. Their low carbon content helps reduce carbide precipitation, enhancing weldability and intergranular corrosion resistance, making Stainless Steel 309S Pipes ideal for extended high-temperature service.
