Stainless Steel 348 Pipes are primarily made of iron, containing 17–19% chromium, 8–11% nickel, along with columbium (niobium) and tantalum to enhance stabilization. These elements significantly improve the material’s resistance to carbide precipitation during welding and exposure to high temperatures. The alloy boasts a tensile strength of about 550–750 MPa and maintains excellent mechanical stability even at elevated temperatures. In its annealed state, 348 stainless steel is non-magnetic and offers good weldability, making it a great choice for applications where heat resistance and corrosion protection are crucial.
