摘　　要：针对20Cr2Ni4钢在应用中存在许多的问题与缺陷,通过分析矿山机械齿轮工况,对比研究了20Cr Ni2Mo与20Cr2Ni4钢的切削性、锻造性、渗层性能、热处理工艺、热处理变形、力学性能、抗过载能力及耐磨性能等。结果表明,采用20Cr Ni2Mo钢替代20Cr2Ni4钢应用于类似矿山机械的重载齿轮是可行的。For many problems and defects in 20Cr2Ni4 steel application, by the analysis of mining machinery gear working condition, the cut ability, forging, carburizing layer performance, heat treatment process, heat treatment deformation, mechanical properties, deformation resistance and abrasion resistance of overload capacity of 20 Cr Ni2Mo and20Cr2Ni4 steel were comparatively studied. The results show that, using 20 Cr Ni2Mo steel instead of 20Cr2Ni4 steel in the mining machinery heavy-duty gear is feasible.
