Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a grain-oriented flat steel product that is intended for the manufacture of parts for electrotechnical applications and has minimised magnetic loss values and optimised magneto-restrictive properties, including the operations providing a flat steel product, laser-treating the flat steel product, wherein, in the course of the laser treatment, linear deformations, which are arranged with a spacing L, are formed into the surface of the flat steel product by means of a laser beam emitted by a laser beam source with a power P. The method according to the invention for producing flat steel products is optimally suited for the manufacture of parts for transformers.
