MANUFACTURING METHOD OF HIGH CARBON STEEL WIRE ROD FOR BEARING STEEL, HEAT TREATMENT METHOD OF HIGH CARBON STEEL BEARING AND HIGH CARBON STEEL BEARING

摘要

A manufacturing method of a high carbon steel wire rod for a bearing, a heat-treating method thereof, and a high carbon bearing are provided to improve abrasion resistance and fatigue resistance of the bearing. A manufacturing method of a high carbon steel wire rod for a bearing comprises the following steps of: hardening a bearing-shaped steel part including 0.95~1.05 weight% of carbon and 1.0~2.0 weight% of silicon; maintaining the hardened part over 1 minutes; and processing the part for 10 minutes or more at temperature of 100~150 °C.
