vSM offers many different conditions of creep resistant 718 Nickel Alloys, commonly referred to as Inconel Alloy 718. AMS 5662 solution treated and AMS 5663 solution treated and aged, as well as many other customer specific conditions. AMS 5662 is the rawest state of 718, and the softest condition of the AMS group. It can be heat treated into AMS 5663. This heat treatment can be done in two ways to achieve specific outcomes such as optimum impact properties, or optimum tensile and creep-rupture properties. The hardness of AMS 5662 Max 28HRC in annealed condition and can increase upon aging to about 36-43 HRC. vSM stocks Alloy 718 (AMS 5662 and 5663) bar between 0.5 – 12.0 dia.
