Abstract
The fracture reason of 3Cr2W8V steel pressure-casting die had been analyzed by mean of chemical compositions analysis,macro examination,metallographic examination and fracture analysis. The results show that there were many big-size carbides or liquation carbides in the steel near the fracture,which resulted in the fracture of the 3Cr2W8V steel pressure-casting die.
