Stainless Steel 309S Tubing

309S stainless steel tubing is an alloy that contains 22-24% chromium, 12-15% nickel, and up to 0.08% carbon. It has other trace elements like molybdenum, silicon, phosphorus, and sulfur. The chemical composition of 309s stainless steel gives the alloy excellent corrosion resistance against various environmental factors such as acids and salt spray. The combination of chromium and nickel also provides superior formability and ductility compared to standard carbon steels.

309s SS tubing is widely used across various industries due to its excellent corrosion resistance and high-temperature strength. Common uses include tube-type heat exchangers, automotive exhaust systems, and process plant equipment. Properties such as formability, weldability, and machinability make this alloy well-suited for manufacturing intricate parts. Additionally, 309s stainless steel tubing offers excellent stress corrosion cracking resistance and toughness across a wide temperature range.
