Abstract

A metallographic study of the carbide phase in rolled sections from bearing steels ShKh15 and ShKh15SG etched in different reagents is performed. The steels are treated by different variants. The experimental results are processed with the aim to correct the mode of spheroidizing annealing of steel ShKh15. The characteristic of the “carbide net remainder” is reduced from 4 – 5 divisions of scale 4 of the GOST 801–78 Standard to 2 scale divisions.
