Featuring outstanding creep-rupture strength at temperatures up to 1300°F, Inconel 718 is a precipitation-hardenable nickel-chromium alloy containing substantial amounts of iron, niobium, and molybdenum, in addition to lesser amounts of aluminum and titanium.
The alloy is typically used in spacecraft, rocket motors, gas turbines, pumps, nuclear reactors, and more because of its combination of corrosion resistance and high strength with outstanding weldability, which includes resistance to postweld cracking.
Inconel 718 requires a minimum yield strength of 150,000 psi at room temperature and is known for its incredible tensile and impact properties even at cryogenic temperatures.
Additional applications include high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.
