Abstract (en)
[origin: WO2006017880A1] A method of manufacturing steel components particularly suited to components such as steering racks having net shape forged gear teeth. The method comprising heating at least a portion of a steel blank to a first temperature of at least 600 °C, forging the portion to shape, cooling the portion in a controlled manner to a second temperature above 200 °C, then immediately heating at least part of the surface of the portion to an austenising temperature, and then quenching the portion to harden the surface.
