目前,在轴承行业使用的各种压力机上,通常沿用国外的3CrW_8V及5CrMnMo作模具材料,其耐磨性、热疲劳性差,寿命低,普遍存在換模次数频繁,模具材料消耗高、设备利用率低,鍛件质量不高等问題。为了寻求性能优良的模具材料,上海钢研所引进行了国外报导的基体钢,加以改进,发展了综合性能较好通用性能较大的含鎳基体钢。经初步试验,证实了基体钢在热挤压轴承套圈模具材料方面的应用非常成功,轴承行业对基体钢的需要也愈来愈迫切。为此,贵阳钢铁
At present, the various presses used in the bearing industry, usually used abroad 3CrW_8V and 5CrMnMo as a mold material, its wear resistance, thermal fatigue, low life expectancy, the prevalence of frequent mold change, mold material consumption, equipment utilization Low, forgings quality is not high and so on. In order to seek high-performance mold materials, Shanghai Steel Research Institute introduced the introduction of foreign reports of the base steel, to be improved, the development of a better overall performance of general-purpose nickel-containing matrix steel. After preliminary tests, it was confirmed that the application of base steel in the hot extrusion bearing ring mold material has been very successful. The bearing industry needs of the base steel is also getting more and more urgent. To this end, Guiyang Iron and Steel
