High performance bearing steel and production method thereof

The invention discloses a high performance bearing steel and a production method thereof, belonging to the field of bearing steel and smelting technology thereof. The bearing steel comprises, by mass, 0.98 to 1.02% of C, 0.28 to 0.40% of Mn, 0.20 to 0.30% of Si, 1.42 to 1.50% of Cr, no more than 0.10% of Mo, no more than 0.010% of P, no more than 0.010% of S, no more than 0.20% of Cu, no more than 0.32% of Ni, no more than 0.0040% of Ti and no more than 0.50% of Ni+Cu, with the balance being iron and unavoidable impurities. The production method for the bearing steel comprises the following melting procedures: smelting in an ultrahigh electric arc furnace; LF refining; VD refining; and continuous casting. According to the high performance bearing steel and the production method thereof in the invention, through controlling of the whole procedures, structural defects of carbide are overcome, the phenomenon of easy generation of hardening cracks is eliminated, wear resistance and fatigue strength of the bearing steel are improved, and thus, performance of the bearing steel is enhanced.
