Abstract

See full text

In one or more first regions of a steel component, a primarily austenitic microstructure can be produced from which a mainly martensitic microstructure can be brought about through a quenching process. In one or more second regions of the component, a mainly ferritic-pearlitic microstructure can be brought about. In one or more third regions, a mainly bainitic microstructure can be brought about. The component is first heated to a temperature below the AC3 temperature in a first furnace, and transferred into a treatment station. The component can be cooled during the transfer. In the treatment station, the first and third regions are brought to a temperature above the austenitization temperature. Only the third regions are cooled to a cooling stop temperature ϑs. The component is transferred into a second furnace, with a temperature lying below the AC3 temperature. There, the temperatures of the three different regions approximate one another.
