Why heat treatment is required for machining mechanical parts

The final heat treatment of mechanical parts machining is to improve the mechanical properties such as hardness, wear resistance and strength of the parts in order to better realize their use value. So do you know what is the specific purpose of heat treatment of mechanical parts processing? Let me share it with you today!

1. Remove the internal stress of the blank. Mostly used for castings, forgings, and welded parts.

2. Improve the processing conditions, so that the material is easy to process. Such as annealing, normalizing, etc.

3. To improve the overall mechanical properties of metal materials. Such as, tempering treatment.

4. To obtain hardness. Such as, quenching, carburizing quenching, etc.
