摘要： A method is provided with which a bearing steel, even when obtained from an ingot, is made to have a segregation part reduced in the degree of segregation and maximum inclusion diameter. The ingot contains 0.56-0.70 mass% C, 0.15-0.50 mass%, excluding 0.50 mass%, Si, 0.60-1.50 mass% Mn, 0.50-1.10 mass% Cr, 0.05-0.5 mass% Mo, up to 0.025 mass% P, up to 0.025 mass% S, 0.005-0.500 mass% Al, up to 0.0015 mass% O, and 0.0030-0.015 mass% N, with the remainder comprising Fe and incidental impurities. The ingot has a degree of segregation of 2.8 or less and a predicted value of the maximum diameter of inclusions present in 30,000 mm 2 of the ingot, as calculated by extreme value statistics, of 60 µm or less.
