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.
