| Abstract: | 5CrMnMo steel forging dies failure early form of crack, deformation of the cavity and collapse. Production through the scene of repeated observation and analysis, microstructure analysis of the mold before and after heat treatment characteristics of the microstructure, forging improved after quenching toughening process, and significantly increase the service life of the die. The average life ex- pectancy was about 20,000. |
