Why Nimonic 90 ?

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
