GH4080A (GH80A) nickel-based superalloy overview

GH80A is based on nickel-chromium and added aluminum and titanium to form a γ ′ phase dispersion-strengthened superalloy. It is similar to GH4033 except for a slightly higher aluminum content. The operating temperature is 700-800 ° C, and it has a good temperature at 650-850 ° C. Creep resistance and oxidation resistance. The alloy has good cold and hot workability. It mainly supplies hot-rolled bar, cold-drawn bar, hot-rolled sheet, cold-rolled sheet, strip and ring, etc. It is used to manufacture engine rotor blades, guide blade supports, bolts, Blade lock plate and other parts.
