Features: Alloy 718 / UNS N07718 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.
