GH4080A is a Ni-Cr-based precipitation hardening deformed high-temperature alloy with a service temperature of less than 800°C. The alloy is mainly formed by adding aluminum and titanium elements to form a phase precipitation strengthening phase. The alloy has good creep resistance and oxidation resistance in the range of 650℃~850℃. The alloy has good cold and hot working properties. The main products include hot-rolled and forged bars, cold-drawn bars, hot-rolled plates, cold-rolled plates, strips and rings, etc.

GH4080A has been used to manufacture aeroengine rotor blades, guide blade supports, sector mounting rings, bolts, blade lock plates and other parts. In addition, it is also used to make fasteners and blades for automobile engines, as well as valves and shafts for trains. In recent years, with the development of domestic and foreign shipbuilding manufacturing industries, this alloy has been widely used in the manufacture of valves for ship engines. No TCP phase precipitated after long-term aging at 700℃~850℃ for 1000h.
