Stainless Steel 347 and 347H Welded Tubing are austenitic stainless steels primarily made up of iron, 17–19% chromium, and 9–13% nickel, with niobium or columbium added to boost stability against carbide precipitation. This unique composition results in remarkable mechanical properties, including high tensile and yield strength, superior creep and oxidation resistance, and stability at elevated temperatures. The 347H variant features a higher carbon content, enhancing its strength at high temperatures. Both types of tubing offer exceptional corrosion resistance, good weldability, and long-term durability, making them ideal for critical applications where high strength, heat resistance, and structural integrity are crucial.
