Nickel and Nickel Alloys- Machining - espimetals.com

Nickel alloys work harden rapidly, and the high pressures produced during machining cause a hardening effect that slows further machining and may also cause warping in small parts. Using cold-drawn stress-relieved material is preferable for machining. Hot-rolled is less desirable and annealed is least preferred for most applications.

The machining of nickel and nickel-base alloys can be readily accomplished providing fundamental principles affecting their machinability are understood and taken into consideration. Compared to other materials, the most significant characteristic of nickel alloys is that they are usually much stronger at metal cutting temperatures.
