WebInconel 718 may be readily machined in either the annealed or age-hardened conditions. The age-hardened condition gives a better surface finish, the annealed condition a longer tool life. Weldability The alloy may be welded in either the aged or annealed conditions. 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.
