Abstract

The invention relates to a bearing steel with a usual bearing steel composition i.e. 100Cr6 or 100CrMn6, exhibiting delayed austenite recrystallization. Said steel contains: 0.80-1.05 mass % carbon; 0.17-0.65 mass % silicon; 0.20-1.20 mass % manganese; 1.30-1.65 mass % chrome; a maximum of 0.027 mass % phosphorous; a maximum of 0.30 mass % nickel; 0.020 mass % sulfur; 0.25 mass % copper; 0.3-1.0 mass % vanadine and/or 0.01-0.1 mass % niobium. Also disclosed is the use of said bearing steel in thermomechanical forming.
