轴承钢技术未来发展方向

[ 关键词:轴承钢技术 发表日期:2019-01-31 09:01:49 ]

  轴承钢主要用于制造滚动轴承的滚动体和套圈。由于轴承应具备长寿命、高精度、低发热量、高速性、高刚性、低噪音、高耐磨性等特性,因此要求轴承钢应具备:高硬度、均匀硬度、高弹性极限、高接触疲劳强度、必须的韧性、一定的淬透性、在大气的润滑剂中的耐腐蚀性能。为了达到上述性能要求,对轴承钢的化学成分均匀性、非金属夹杂物含量和类型、碳化物粒度和分布、脱碳等要求严格。轴承钢总体上向高质量、高性能和多品种方向发展。轴承用钢按特性及应用环境划分为:高碳铬轴承钢、渗碳轴承钢、高温轴承钢、不锈轴承钢及专用的特种轴承材料。
