Stainless Steel 347 and 347H Welded Tubing is stabilized with niobium and contains chromium (17–19%) and nickel (9–13%), giving it strong resistance to intergranular corrosion. Grade 347H has a higher carbon content, enhancing high-temperature strength and creep resistance. The tubing offers excellent tensile strength, good ductility, and stable mechanical performance even under thermal stress. Its superior oxidation resistance, weldability, and structural integrity make it reliable for continuous high-temperature service. These characteristics collectively ensure durability and consistent performance in harsh industrial environments.
