Heat-treating a workpiece from corrosion-resistant bearing steel, which is present in the form of ring such as an outer ring, an inner ring, and/or a rolling body of a roller bearing, comprises austenitizing and quenching of the workpiece

摘要

The method for heat-treating a workpiece from 440C corrosion-resistant bearing steel, comprises austenitizing and quenching (13) of a workpiece. The austenitization of the workpiece is carried out at 1100-1150[deg] C for 10-30 minutes, and the workpiece is quenched under vacuum with a moderate cooling rate of 0.2-2. The heat treatment is carried out using vacuum oven. An independent claim is included for a workpiece.
