These fittings are stabilized with niobium and boast a composition of 17–19% chromium, 9–13% nickel, along with trace elements of carbon, manganese, silicon, phosphorus, and sulfur. The addition of niobium enhances their resistance to intergranular corrosion, especially after being exposed to high temperatures. With a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa, they also excel in creep and stress rupture properties. Their mechanical strength, toughness, and stability at elevated temperatures make them reliable in high-stress and corrosive environments.
