Abstract
A method of manufacturing a component of a rolling-element bearing includes: providing a steel body having a carbon content of less than 0.3 weight-%, a chromium content of greater than 8.0 weight-%, and a nitrogen content of less than 0.1 weight-%; high-temperature solution nitriding the steel body; after the high-temperature solution nitriding, performing an intermediate tempering process to reduce a size of austenite grains in the steel body; and after the intermediate tempering process, performing a reaustenitizing annealing. Also the component made by the method.
