The applicability of hobbing die made by ausforming process was tested using 0.4C-1Mn-3Cr-2Mo-1V hot work tool steel which had excellent thermal shock and fatigue resistance. Basic experiments on ausforming showed the increase in hardness and toughness of this steel, which was derived from the refinement of microstructure. The hot work steel die for bevel gear was hobbed in this ausforming process (HA-Process) and the longer tool life than conventional electric-discharge-machined die was achieved in |
