Zusammenfassung:	A method for producing a semifinished material for the production of metallic components having regions of different strength may involve, in a first step, providing thermal energy to a first region of the semifinished material that is uncoated such that the first region is heated and a material structure in the first region is converted at least partially into austenite. Meanwhile, thermal energy may prevented from being supplied to a second region of the semifinished material. In a second step following the first step, the first region may be cooled such that the material structure in the first region is converted at least partially into martensite.
