| Abstract: | High strength weathering steel had high requirements for processing formability, and it was easy to crack during the stamping process. By analyzing the morphology of shear band and principle of stamping process of high strength weathering steel, the reason for cracking during the stamping process was analyzed. Measures such as composition optimization and process adjustment were taken to avoid cracking during the stamping process. Therefore, high strength weathering steel with excellent processing formability was obtained. |
