    The most common heat treatments applied to gray cast irons are stress relief because of nonuniform cooling of cast-ings and annealing to improve machinability. Subcritical heating is used for both. Stress relief is done at temperatures between 1020 and 1200˚F (550 and 650˚C) without sig-nificantly lowering strength and hardness.
