3Cr2W8V热锻模钢的淬火温度长期以来都倾向于选用1050～1100℃,一般认为过高的淬火温度将使钢的塑性降低,在这种温度下淬火,再经过560℃回火处理,其硬度为HRc42～46。我们在生产实践中发现,这样处理的模具热稳定性较差,在模锻过程中,由于反复跟炽热锻件接触锻压,模具的强度和硬度下降、耐磨性变差,以致较早发生模面棱角磨损及局部凹陷等,影响锻件质量进而使模具报废,在 3Cr2W8V hot forging steel quenching temperature has long tended to choose 1050 ~ 1100 ℃, generally considered too high quenching temperature will reduce the plasticity of steel, quenched at this temperature, and then tempered at 560 ℃, the hardness HRc42 ~ 46. We found in production practice, so that the thermal stability of the mold is poor, in the forging process, due to repeated contact with the hot forging forging, mold strength and hardness decreased, poor wear resistance, resulting in earlier mold surface Angular wear and local depression, etc., affecting the quality of forging and mold scrapped, at
