Alloy Steel WP9 pipe fittings are made from a chromium-molybdenum steel alloy, primarily consisting of 0.07–0.15% carbon, 0.90–1.10% chromium, and 0.40–0.60% molybdenum. This composition provides excellent high-temperature strength and resistance to oxidation. The mechanical properties include a tensile strength of around 85–105 ksi (585–725 MPa), yield of approximately 50 ksi (345 MPa), and elongation of 20-30%. It offers good weldability and is highly resistant to creep and corrosion, making it ideal for power plants and other high-temperature applications.
