Stainless Steel 348/348H Forged Fittings have superior chemical, mechanical, and physical properties. Chemically, they consist of chromium (17–20%), nickel (9–13%), and stabilization with niobium to avoid carbide precipitation during welding. 348H has a greater carbon content for increased high-temperature strength. Mechanically, they have a tensile strength of around 515 MPa and a yield strength of around 205 MPa, with excellent ductility and creep resistance. Physically, their density is around 7.96 g/cm³, and they retain structural integrity at temperatures up to 1,100°C.
