A high strength and high fatigue resistance alloy, Inconel 718 is designed for extended usage at extreme temperatures. Ductility and toughness remain high, though it cannot be cold worked. Inconel 718’s service temperatures run from cryogenic to 1200 F (649 C). Typically used in gas turbines, liquid fuel rocket motors, springs, fasteners, and cryogenic tanks.
