Stainless Steel 348 Tubing is an austenitic stainless steel that is stabilized with niobium and tantalum. It consists of chromium, nickel, iron, low carbon, manganese, silicon, and stabilizing elements. This stabilization helps prevent carbide precipitation and improves resistance to intergranular corrosion, especially after welding or when exposed to high temperatures. SS 348 is known for its good tensile strength, excellent ductility, and strong oxidation resistance. Its mechanical properties remain stable even under thermal cycling, ensuring dependable performance in challenging operating conditions.
