he causes of the formation of a crack

High index of cold work hardening of austenitic stainless steel (stainless steel, 0.34). The metastable austenitic stainless steel model, the deformation phase transition happens, the induced martensite phase. Martensite than brittle, so prone to cracking. During plastic deformation,, with the increase of the deformation induced martensite content will also be increased with the increase of the deformation and residual stress. : the relationship between residual stress and the martensite content induced martensite phase content is higher, the cause of residual stress is, the greater the during processing are also more prone to cracking.

2 the causes of the formation of surface scratch

The scratch on the surface of the deep drawing of stainless steel is mainly due to the workpiece and die surface

To move, to a certain pressure, under the action of the local surface of billet and the mold friction directly, combined with the deformation of the billet hot billet and scrap metal deposition in the mold on the surface, the surface scratch scratch.
