The causes of the crescent shape crack faults of HP295 drawing were studied. The results showed that the formation of these faults was mainly related to the stress state of stamping and drawing, as well as the slender MnS inclusions distributed along the rolling direction. Moreover, it was the center segregation and the obvious banded structure that further improve the formation of the crescent shape crack fault.
