ALLOY 718 | 2.4668 - Data sheet

UNS N07718 | AMS 5662 | AMS 5663 | ASTM B637 | AMS 5596 | ASTM B670 | DMD 424-22

Alloy 718 is a precipitation hardened nickel-chromium alloy with additions of niobium, molybdenum, aluminum and titanium for improved corrosion resistance combined with extremely high strength and excellent weldability, including resistance to cracking after welding. Alloy 718 has excellent creep rupture strength at temperatures up to 700 °C. Alloy 718 achieves its strength through a precipitation hardening heat treatment and can be supplied in a ready-to-anneal solution to facilitate processing, after which it is heat treated to achieve full strength, or the material can be supplied in the fully precipitation-hardened state.
