Non-magnetizable rolling bearing component of an austenitic material and method of making such a rolling bearing component

摘要

A non-magnetizable rolling bearing component made of an austenitic material and comprising a hardened surface layer wherein the component of the invention is a material used for making the component contains manganese and a method for making such a rolling bearing component wherein the surface-proximate layer of the material of the rolling bearing component contains an admixture of manganese, is carburized at an elevated temperature in an oxygen-rich atmosphere and the rolling bearing component is then cooled.
