These fittings are made up of chromium (22–24%) and nickel (12–15%) with a low carbon content, which not only boosts their weldability but also minimizes the chances of carbide precipitation during welding. They boast a tensile strength of around 515 MPa and a yield strength of about 205 MPa, all while maintaining good ductility and mechanical stability under high heat. This alloy is particularly resistant to oxidation, carburization, and hot corrosion, even at temperatures reaching up to 1000°C.
