This Alloy is a wrought nickel-chromium-cobalt base alloy strengthened by additions of titanium and aluminum. It has been developed as an age-hardenable creepresisting alloy for service at temperatures up to 920°C(1688°F.The alloy is used for turbine blades, discs, forgings,ring sections and hot-working tools.

This alloy is mainly strengthening phase γ’i3(Ti、). Aging deformation of cobalt nickel base superalloy, containing a high amount of cobalt and
a variety of reinforcement element, higher tensile strength and creep resistance in 815 ~ 870 ℃ , good resistance to oxidation and corrosion resistance,
in cold and hot again and again under the action of alternating, showing high fatigue strength and good formability and weldability
