718 (AMS 5663)
Inconel® 718 (AMS 5663) is bar that is already aged (precipitation hardened). As supplied, this material provides higher tensile strength and hardness compared to 718 in the annealed condition. Machining aged 718 is generally more difficult than machining annealed material. The benefit is that once machining is completed the part is complete.
Avoiding post machining heat treatment has several benefits since it eliminates the issue of dimensional change during aging. It also provides significant logistical advantages.
