Often referred to as Inconel® 718, this austenitic nickel based super alloy is designed primarily for strength in temperature extremes. A precipitation hardening alloy, Alloy 718 displays exceptionally high yield, tensile and creep-rupture properties at temperatures well below freezing up to and beyond 1300°F (704°C). As a specialty alloy, 718 has improved mechanical short and long-term properties vs. other nickel alloys, and great fatigue strength in the age hardened conditions. Alloying material includes very specific mixtures of niobium, molybdenum, titanium, and aluminum to assist with performance properties, as well as precipitation hardening. A versatile solution, Alloy 718 is available in many forms and produces results in a range of extreme applications.
Inconel® 718 Composition
Depending on the standards applied and the form of material, Alloy 718 can be specified through many of the following:
