GH4145 Superalloy alloy steel

GH4145 alloy mainly γ "[Ni3 (Al, Ti, Nb)] with aging strengthened nickel-base superalloy, below 980 ℃ with good resistance to corrosion and oxidation resistance below 800 ℃ with high strength, below 540 ℃ has good resistance to relaxation properties, but also has good formability and weldability. the alloy is mainly used in the manufacture of aviation engines work below 800 ℃ and require higher strength and resistance to relaxation of the flat spring coil spring. can also be used in the manufacture of gas turbine turbine blades and other parts. can supply a variety of sheet, strip, bar, forgings, circular pieces, wire and tubing.

GH4145 Nickel alloy similar material are: W.Nr.2.4669

GH4145 Application field are:
The alloy has a high temperature environment good corrosion resistance and creep rupture strength, good mechanical properties, is widely used, below 980 ℃ have sufficient strength and corrosion resistance to oxidation

Producing a high temperature working spring, a bolt; gas turbine rotor blades on the impeller and other structural members;
On the rocket engine thrust chamber;
Thrust reverser on the plane;
Large pressure vessel;
Elastic gas were mounted, flexible seal die, rubber machinery electric blade.
