1, complete annealing: heating 390 ~ 430 ℃; with the effective thickness of the material is different, the holding time of 30 ~ 120min; 30 ~ 50 ℃ / h with the speed of the furnace cold to 300 ℃, and then air-cooled.
2, fast annealing: heating 350 ~ 370 ℃; with the effective thickness of different materials, holding time 30 ~ 120min; air or water cooling.
3, quenching and aging: quenching 500 ~ 510 ℃, air-cooled; artificial aging 95 ~ 105 ℃, 3h, air-cooled; natural aging room temperature 120h
