The solution anneal at 925-1010˚C (1700-1850˚F) with its corresponding aging treatment is considered the optimum heat treatment for Inconel® 718 where a combination of rupture life, notch rupture life and rupture ductility is of greatest concern. The highest room-temperature tensile and yield strengths are also associated with this treatment.
