Stainless Steel 309 Tubing is an austenitic alloy characterized by a high content of chromium and nickel, typically featuring around 22 to 24 percent chromium and 12 to 15 percent nickel. This unique composition grants it exceptional oxidation resistance, corrosion resistance, and thermal stability. In terms of mechanical properties, 309 tubing boasts good tensile strength, moderate yield strength, and impressive toughness, even at elevated temperatures. It also offers excellent creep resistance, weldability, and formability. These attributes ensure dependable performance in high-heat settings while maintaining dimensional stability, ductility, and structural integrity throughout fabrication and long-term use.
