It adopt to heating bending to do the plate bending, there is no exist great bending stress. That’s to say each plate heating energy absorbed is basically consistent, do not exist heating too short or too long. Therefore will not appear the crack or metal inter-granular crack in the process of bending
Due to the limitation on the product design, the plate must be bending before heat treatment, so the bending parts and other parts have the same hardness and the strength. But is will causing the metal plasticity be greatly reduced, Although it can bearing the force of reverse bending, but under this action, it will be breakage.
