Stainless Steel 347/347H Welded Tubing is stabilized with niobium and contains chromium, nickel, and carbon. 347H has a higher carbon version for enhanced high-temperature strength. Such composition improves resistance to intergranular corrosion, oxidation, and carbide precipitation. Both grades provide very good creep strength, tensile strength, and toughness at elevated temperatures. 347H is more stable during long-term heating than the others. These properties make the tubing very reliable under thermal cycling, pressure-handling, and structural conditions in severe industrial settings.
