  • Heat-Treatment Process for a Steel
    Publication number: 20110073222
    Abstract: A process for inducing a compressive residual stress in a surface region of a steel component, the process comprising a heat treatment having the following steps: (i) providing a component comprising a steel composition; (ii) induction heating at least a part of the component followed by quenching said at least part, wherein the hardness in a surface region of the component is increased; and (iii) subsequently performing a martensite and/or bainite through hardening step to obtain a microstructure comprising martensite and/or bainite.

  • Rolling bearing steel having a surface with a lower bainitic structure and a method for the production thereof
    Patent number: 6475309
    Abstract: A method for producing a rolling bearing component, in which, before ustenizing, the steel is subjected to cold deformation and quenching is such that the bainitic structure is obtained; and a rolling bearing component produced by the method, such as a rolling bearing ring from 1C to 1,5Cr type series steel, in which at least the surface of the rolling bearing component has a bainitic structure and the service life of the bainitic structure is considerably increased over a component not subjected to cold rolling.
