Stainless Steel 347H Seamless Tubes are composed primarily of iron, with additions of chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), manganese (≤2%), silicon (≤1%), and niobium (≤1%) for enhanced stability. These elements provide excellent resistance to corrosion, oxidation, and high-temperature environments. The tubes exhibit superior mechanical properties, including a tensile strength of 515 MPa (min), yield strength of 205 MPa (min), and elongation of 40% (min). Their high creep and stress rupture resistance make them ideal for elevated temperature and pressure applications.
