Nimonic80A is a γ 'dispersion-strengthened superalloy formed byadding aluminum and titanium with ni-Cr as matrix. It is similar toGH4033 except that the aluminum content is slightly higher. It hasgood creep resistance and oxidation resistance at 700 ~800℃ and 650 ~ 850℃. The alloy has good cold and hot workingperformance, mainly supplying hot rolled bar, cold drawn bar, hotrolled plate, cold rolled plate, strip and annular parts, etc.,used for manufacturing engine rotor blade, guide blade support,bolt, blade lock plate and other parts.
