Abstract: | In this paper, test and analysis for the hardened big crystal of natural W9Mo3Cr4V steel has been done,It points out the nonenough hardened material is the key factor of fracture of the products after heat-treatment in the tool manufacturers. Therefore, the suggestion to use enough anneal method to prevent this shortcoming. |
