Features: Inconel 718 is an age-hardenable nickel-chromium alloy that combines corrosion resistance with high strength and good fabricability. It has high creep-rupture strength at temperatures up to 700℃. Its excellent relaxation resistance contributes to its application in springs.

Applications: Gas turbine engines, rocket motors, nuclear reactors and spacecraft.
