Inconel 718®

Alloy 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300®F (704®C). The age-hardening response of Alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. Alloy 718 has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium. Alloy 718 is used in aircraft engine parts and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.
