低碳马氏体由于其组织形态上的特殊性而具有优良的综合机械性能,尤其是与中碳钢淬火后中温回火状态相比较,更具有高的强度和良好的韧性、塑性,还具有高的断裂韧性和多冲抗力,以及耐疲劳、耐磨等性能。因此,这种淬火工艺已愈来愈多地被机械行业所推广应用,并且取得显著的经济效果。目前这种工艺多用在轴类、紧固件、农机具等一般取代中碳钢或渗碳钢的零件上。能否在弹性元件上应用呢?这是本文所要探讨的问题。我们通过半年多的应用试验证明,低碳马氏体淬火工艺同样可以用在弹性元件上。我厂是从1979年上半年开始对模具零件上部分原采用中碳钢的垫板、挡块、顶料器等结构件试用了低碳马氏体淬火法,以 A3普通钢材代替,完全满足了技术要求,材料费可降低 Low-carbon martensite has excellent comprehensive mechanical properties due to its special morphological characteristics, especially compared with medium-temperature tempering of medium-carbon steel after quenching, with higher strength, good toughness and ductility, and also has High fracture toughness and multi-impact resistance, and fatigue-resistant, wear-resistant properties. Therefore, this quenching process has been more and more widely applied by the machinery industry, and achieved significant economic results. At present, this technology is mostly used in the shaft, fasteners, agricultural machinery and other general replacement of carbon steel or carburized steel parts. Can it be applied on flexible components? This is the problem to be explored in this article. Through more than six months of application tests, we prove that the low carbon martensitic quenching process can also be used on flexible components. I plant from the beginning of the first half of 1979 on the part of the original mold parts used in the carbon steel plate, stopper, ejector and other structures of low carbon martensitic quenching test method to replace the ordinary steel A3, fully meet The technical requirements, material costs can be reduced
