| 摘 要： | 降低高碳铬轴承钢中的网状、带状碳化物等不利因素,有利于提高轴承钢的综合性能。G8Cr15是新纳入到国家标准中的轴承钢,通过系列试验,对比传统GCr15轴承钢和新的G8Cr15轴承钢的各项性能。结果表明,与GCr15轴承钢相比,G8Cr15轴承钢生成网状碳化物和带状碳化物的能力极低,同时具有更高的淬透性、良好的冲击性能和耐磨性。经工业生产验证,G8Cr15可替代GCr15用于生产轴承零件,且不易产生网状碳化物。 |

| Abstract: | Reducing the disadvantageous factors such as network and banded carbides in high carbon chromium bearing steel is beneficial to improve the comprehensive properties of bearing steel. G8cr15 bearing steel is a type of bearing steel newly-included in the national standard, and the performances of GCr15 and G8Cr15 are compared through a series of experiments. The results show that as compared with GCr15 bearing steel, G8Cr15 bearing steel shows very low ability of forming network carbide and ribbon carbide, and it also exhibits higher hardenability, good impact properties and wear resistance. Finally, it is verified by industrial production that G8Cr15 can replace GCr15 to produce bearing parts, and it is unlikely to produce network carbide. |
