The composition of Stainless Steel 347/347H Seamless Tubing primarily includes iron, chromium (17–19%), nickel (9–13%), and niobium, which helps stabilize the alloy against carbide precipitation. The 347H variant features a higher carbon content, enhancing its strength at elevated temperatures and improving creep resistance. These tubes are known for their excellent corrosion and oxidation resistance, with tensile strength ranging from 515–700 MPa. They maintain their structural integrity even under high temperatures and offer good weldability and formability. The stabilized composition makes them particularly well-suited for applications that involve frequent thermal cycling and exposure to corrosive environments.
