A method for post-treatment of single high-grade steel blanks produced from deep-drawable circles or sections of high-grade steel by deep-drawing, pressing, rolling and deformation. According to this invention, the completed blanks are post-treated directly after being produced, in a drum which is hard-faced with hard granulate particles and which moves in a rotating manner. Thus, changes in the surface of the single high-grade steel blanks produced, caused by material stresses occurring during the production process, are avoided, provide the high-grade steel blanks with an optimum appearance. |
