These fittings primarily consist of 18–20% chromium, 8–11% nickel, and a higher carbon content of 0.04–0.10%, which boosts their strength at elevated temperatures. They boast a tensile strength of around 515 MPa and a yield strength of 205 MPa, providing remarkable toughness and resistance to heat and corrosion. The added carbon content enhances their creep resistance and mechanical stability, making them perfect for high-temperature applications.
