The present invention, on the one hand, enables optimal tribological conditions during the molding of flat steel products while minimizing the demand for lubricants, and on the other hand, as a coating material acceptable in terms of environmental impact, "aluminum sulfate, ammonium sulfate" , iron sulfate, magnesium sulfate" group. A flat steel product is provided, and a tribologically effective layer is placed on at least one of the faces of the flat steel product that are in contact during forming or the faces of a forming machine used for forming, "aluminum sulfate, ammonium sulfate, iron sulfate, sulfuric acid" It is produced by coating with a coating material from the "magnesium" group, the flat steel product is inserted into a forming tool, and the flat steel product inserted into the forming machine is formed into a part, so that, with the coating material, the steel part is formed in the forming machine. It can be manufactured through molding of flat steel products. |
