Abstract

The paper presents a comparative analysis of the microstructure, size and distribution of carbides, hardness and tribotechnical properties during research and testing under the same conditions of bearing steel grades 60Kh13S-ShD, 95Kh18-Sh and 110Kh18M-ShD, commercially used in the Russian industry. Based on the results of the research, steel grades were identified that have the best set of properties after hardening heat treatment.
