Abstract:
1. A method for producing a hardened component from a hardenable steel, comprising: subjecting a steel strip of a type 22MnB5 to a temperature increase and, in the process, an oxidizing treatment in a furnace chamber, so that a superficial oxide layer is produced; after the superficial oxide layer has been produced, coating the steel strip with a metal or a metal, alloy, and, in order to produce an at least partially hardened component, heating the strip and at least partially austenitizing the strip and then cooling off and thus hardening the strip; and in order to produce a superficial ductile layer, partially reducing oxides at the surface of the strip prior to coating the strip with a metal or a metal alloy, thus producing a very thin reduced layer located on a residual oxide layer; wherein an area of an inner oxidation is located beneath the residual oxide layer in the strip, in which steel-alloy elements are present in a partially oxidized form.
