摘要
梳理了高碳铬轴承钢现行的标准,列出了这些标准的标准号、名称、标准类别、标准适用范围及标准体系类别;同时以某钢铁企业为例,选用牌号成分接近的GCr15、GCr15PGI的高碳铬轴承钢的内控标准与GB/T 18254-2016及ISO 683-17进行比较,说明了不同标准对于GCr15牌号成分及相近成分轴承钢在碳化物、夹杂物及化学成分上的要求,发现我国GB/T 18254-2016较ISO 683-17更为严格,而企业内控标准则在GB/T 18254-2016的基础上做了更深入的要求。
The current standards for high carbon chromium bearing steel were combed. The standard number, name, category, application scope and standard system category were listed. Meanwhile, the internal control standard of high carbon chromium bearing steel(GCr15 and GCr15 PGI) with similar grade and composition was selected for the comparison with GB/T 18254-2016 and ISO 683-17 taking a steel enterprise as an example. It explained the requirements of different standards on carbides, inclusion, and chemical composition of GCr15 and other bearing steel with similar composition. It was found that the requirements of GB/T 18254-2016 were stricter than ISO 683-17, and internal control standard of enterprise had further requirements based on GB/T 18254-2016.
