Does INCONEL 718 need to be heat treated?
Two heat treatments are generally utilized for INCONEL alloy 718: •Solution anneal at 1700-1850°F followed by rapid cooling, usually in water, plus precipitation hardening at 1325°F for 8 hours, furnace cool to 1150°F, hold at 1150°F for a total aging time of 18 hours, followed by air cooling.
Does INCONEL 718 work harden?
Inconel 718 is one of the most difficult-to-cut materials, due to its toughness, lower thermal conductivity and easy work hardening properties. Furthermore, as a kind of easy work hardening material, Inconel 718 suffers several plastic deformations during the machining process.
