| Abstract: | In the case of the 3Cr2W8V hot forging dies for the crosscut nip application, the failures were early cracking and hot wear sunk. Using metallographic microscope to analysis microstructure feature of heat treatment of 3Cr2W8V hot forging dies. By improving the heat treatment technology, the control and the guarantee mold achieves the certain hard level depth, the 3Cr2W8V hot forging dies life has been prolonged in a big range, the mean lifetime achieves 20,000. |
