Inconel 718 is one of the most difficult-to-cut materials, due to its toughness, lower thermal conductivity and easy work hardening properties.

Can you harden Inconel?

INCONEL alloy 725 is one such material, with extremely high strength, achieved through precipitation hardening. This heat treatment increases the yield strength, which produces materials that are particularly tough and strong, even in high-temperature situations.

Is Inconel hard to machine?

Inconel 718 is known to be among the most difficult-to-machine materials due to its special properties which cause the short tool life and severe surface damages.
