Products Description
Nickel Alloy 718 maintains high strength and good ductility and oxidation resistance up to high temperatures; conversely it has outstanding cryogenic properties. An example of these combined characteristics used in one application can be seen in the aerospace industry. Nickel Alloy 718 provides vital strength aircrafts require, it can withstand both the intense heat of the afterburners and the freezing temperatures experienced at high altitude.NSA offers many different conditions of Nickel Alloy 718: AMS 5662 solution treated, AMS 5663 solution treated and aged, AMS 5664 solution treated and aged, NACE MR-01-75, and many 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 is about 20-25 HRC and can increase upon aging to about 36-44 HRC. Some prefer to machine their parts in AMS 5662 and later heat treat to their desired specification to the softness of the material, while others prefer the opposite machining their parts afterwards. Regardless, the same outcome of AMS 5663 is achieved.
AMS 5564 is different than the other AMS specifications; it has a more complicated forming process and is available through NSA upon mill run. The outcome is a higher tensile and yield strength, along with specific grain size restrictions. These restrictions enable AMS 5664 to have a higher strength which is desired for some aerospace applications.
