Embodiment Construction
[0009] The present invention will be further illustrated below in conjunction with specific embodiments, and it should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0010] An alloy steel formula for bearings disclosed by the present invention has the weight percent of each component (wt%): carbon: 0.37-0.45; molybdenum: 0.24-0.29; zirconium: 0.33-0.39; silicon: 0.17-0.37; manganese: 0.50-0.80; sulfur: less than 0.04; phosphorus: less than 0.05; chromium: less than or equal to 0.25; nickel: less than 0.25; copper: less than 0.25; other inevitable impurities: less than 0.1; the balance is iron. Steel die forging temperature is 1200±50°C, final forging temperature is 950-1050°C, air-cooled to 800-900°C in non-oxidizing medium after final forging, then water-cooled to room temperature, sampling 10 groups of 40*40mm column samples, the average of the samples ...
