Weldment welded to the stress annealing heat treatment plant in Dongguan

Stress relieving heat treatment process to remove stress, annealing casting, forging, weldment upon cooling Because of different parts of the cooling rate resulting in stress, metals and alloys in the cold deformation and artifacts are generated in the cutting process of internal stress. If a larger internal stress without timely be removed, often resulting in the formation of cracks or deformation of the workpiece. Stress relief annealing to remove the workpiece is slowly heated to a lower temperature (for example, gray cast iron is 500 ~ 550 ℃, the steel is 500 ~ 650 ℃), holding for some time, the metal inside relaxes, and then slowly cooled down. It should be noted, it is not capable of stress relief annealing to remove internal stress completely, but only partially removed, so as to eliminate its harmful effects.
