These fittings are primarily made of iron, containing 17–19% chromium, 9–13% nickel, along with niobium and carbon to boost creep resistance. The “H” designation signifies a higher carbon content, which enhances strength at elevated temperatures. They boast impressive tensile strength (around 515 MPa), yield strength (205 MPa), and elongation (40%). Even at high temperatures, they maintain good toughness and ductility, offering excellent resistance to intergranular corrosion, oxidation, and scaling, even in continuous service up to 900°C.
