GH80A is a high temperature alloy with nickel-chromium as the matrix, aluminum and titanium added to form r-phase dispersion strengthening. Except for the slightly higher aluminum content, the others are similar to GH4033. The operating temperature is 700-800ºC, and it has a good performance at 650-850ºC. Creep performance and oxidation resistance. The alloy has good hot and cold processing performance. It mainly supplies hot-rolled bars, cold-drawn bars, hot-rolled plates, cold-rolled plates, strips and ring parts, etc., used to manufacture engine rotor blades, guide blade supports, bolts, blades Parts such as lock plates.
