Conclusions
-
1.
Titanium-modified heat-resistant bearing steel 8Kh4M4V2F1T-Sh is not susceptible to overheating during quenching, can be quenched from a broad range of temperatures, and has high mechanical properties.
-
2.
The contact fatigue strength of titanium-modified steel 8Kh4M4V2F1T-Sh exceeds that of steels 8Kh4V9F2-Sh and 8Kh4M4V2F1-Sh.
