This grade is used in many demanding applications based on its high temperature resistance and superior oxidation and corrosion resistance. Originally developed and used for gas turbines, aircraft engines, fasteners and other high strength applications. It also has excellent potential for cryogenic applications.
High strength Alloy 718 can be obtained via heat treatment to achieve the required properties. AMS 5662 is in the solution annealed condition, usually with a capability test to ensure future compliance to AMS 5663. It is the softest of the Alloy 718 ‘states’ which can sometimes offer a machining benefit to our customers.
The material is then aged after machining to meet the mechanical requirements. AMS 5663 is in the solution treated and aged condition to give high strength tensile properties.
