摘要： A bearing steel is provided which can satisfy bearing property requirements and, at the same time, is improved in mechanical properties, such as impact, crushing, and transverse properties, while reducing the cost of materials and the cost of heat treatment for the production of a bearing. The bearing steel comprises by weight C: 0.70 to 0.93%, Si: 0.15 to 0.50%, Mn: 0.50 to 1.10%, Cr: 0.30 to 0.65%, and N: 0.005 to 0.02% with the balance consisting of Fe and unavoidable impurities and 0.4.ltoreq.Cr/C.ltoreq.0.7, the steel further comprising at least one of (1) Al: 0.01 to 0.1% with Al.times.N.gtoreq.0.00015 and (2) Nb: 0.02 to 0.1%. A rolling bearing produced from the bearing steel is also provided.
