Abstract��By analyzing crack samples of hot forging for 45 round steel from both macro and micro, it can be found that the crack was mainly caused by folding, and local surface decarburization of round steel sharpened the crack of hot forging. By implementing regulations on overhaul and rolling strictly, and optimizing heating institution, the crack of hot forging could be prevented.
