These fittings are made from niobium-stabilized austenitic stainless steels, which contain 17–19% chromium, 9–13% nickel, along with trace elements of carbon, manganese, and silicon. The addition of niobium boosts their resistance to intergranular corrosion and enhances stability at high temperatures. They boast a tensile strength of around 515 MPa and a yield strength of approximately 205 MPa, along with excellent resistance to creep and stress rupture. Even in elevated temperatures, they maintain remarkable mechanical strength and toughness, providing outstanding oxidation resistance and durability, making them ideal for challenging environments that involve heat, pressure, and corrosive conditions.
