Stainless Steel 347 Pipe Fittings are primarily made up of iron, chromium (17–19%), nickel (9–13%), and are stabilized with niobium (up to 0.5%) to prevent carbide precipitation during welding. These fittings boast excellent resistance to intergranular corrosion and oxidation at high temperatures. In terms of mechanical properties, they have a tensile strength ranging from 515 to 750 MPa, a yield strength of 205 to 275 MPa, and an elongation of 40 to 50%, ensuring they are both strong and flexible. The niobium stabilization not only enhances weldability but also helps maintain structural integrity in high-temperature and corrosive environments, making 347 fittings a reliable choice for industrial piping systems.
