Heat Treatment

(1) Fast annealing: heating temperature 350 ~ 410°C; The holding time is between 30 and 120min depending on the effective thickness of the material. Air or water cooling.

(2) High temperature annealing: heating temperature 350 ~ 500°C; When the thickness of the finished product is greater than or equal to 6mm, the holding time is 10-30min, and when the thickness is less than 6mm, the heat penetration is reached. The cold air.

(3) Low temperature annealing: heating temperature 150 ~ 250℃; Holding time is 2 ~ 3h; Air or water cooling.
