Age hardened inconel 718
WebMar 20, 2024 · Inconel 718 is an age hardened nickel-based superalloy, which is one of the most widely used alloys in aerospace engine components. IN718 was developed for high temperature service, as such... WebFor this reason, age-hardened Inconels such as 718 are machined using an aggressive but slow cut with a hard tool, minimizing the number of passes required. Alternatively, the majority of the machining can be performed with the workpiece in a solutionized form, with only the final steps being performed after age-hardening.
