These Alloy Steel F91 forged fittings are primarily made of iron, with about 9% chromium and 1% molybdenum, along with small amounts of vanadium, niobium, and carbon. This meticulously engineered blend provides remarkable high-temperature strength, creep resistance, and oxidation resistance. The mechanical properties boast a tensile strength of 620–750 MPa, yield strength of 450–550 MPa, and hardness between 200–250 HB. Additionally, these fittings exhibit excellent impact toughness and fatigue resistance, making them suitable for high-stress, high-temperature environments. Precision forging and heat treatment further enhance their dimensional stability and mechanical performance.
