Bearing parts are formed of damping steel containing 0.2 to 0.6 wt. % C, 5.0 to 15.0 wt. % Cr, 0.2 to 1.3 wt. % Si, 0.05 to 0.20 wt. % N, and comprising Fe and inevitable impurities as the remaining. The damping steel may be hardened in an ordinary manner to have a surface hardness, in terms of Rockwell C hardness of at least 57.
