Inconel® 718 AMS 5662 available at Rockwell Industries (Inconel alloy 718, inco718, inc718, alloy718) is a nickel-chromium-molybdenum alloy designed to resist a wide range of corrosive environments, pitting and crevice corrosion. Rockwell Industries Inconel 718 nickel alloy also displays high tensile and creep-rupture properties at elevated temperatures.  One of the distinguishing features of Inconel 718 material (ni alloy 718) composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling. In addition, the niobium acts with the molybdenum to stiffen the alloy’s matrix and provide high strength without a strengthening heat treatment. Other popular nickel alloys are often age hardened through the addition of aluminum and titanium. This nickel steel alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition.

Common applications are jet engine components, bolts, fasteners, afterburners, oil & gas. Rockwell Industries has Inconel 718 for sale in the following sizes below.
