These fittings are made from a blend of chromium (22–24%) and nickel (12–15%), along with a higher carbon content that boosts creep strength and high-temperature performance. They deliver a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa, while also showcasing impressive ductility and oxidation resistance up to 1000°C. The low sulfur content in the alloy enhances its resistance to carburization and corrosion, ensuring consistent performance even under continuous thermal stress.
