Stress relief annealing is an annealing process performed to eliminate residual stress caused by plastic deformation processing, welding, etc. and existing in castings.
There are internal stresses inside the workpiece after forging, casting, welding and cutting. If not eliminated in time, the workpiece will be deformed during processing and use, affecting the accuracy of the workpiece. It is very important to use stress relief annealing to eliminate the internal stress generated during the processing.
The heating temperature of stress relief annealing is lower than the phase transformation temperature, so no structural transformation occurs during the entire heat treatment process. Internal stress is mainly eliminated through the process of heat preservation and slow cooling of the workpiece. In order to eliminate the internal stress of the workpiece more completely, the heating temperature should be controlled during heating. Generally, it is put into the furnace at low temperature, and then heated to the specified temperature at a heating speed of about ℃/℃. The heating temperature of the welded parts should be slightly higher than ℃. The holding time depends on the situation, usually ~. The holding time for stress relief annealing of castings is set to the upper limit, and the cooling rate is controlled at (~)°C/can be air-cooled only when it is cooled to below 3°C.
