Abstract:
A method for producing round stock (10) which is provided with at least one inscription and/or marking (16), at least the surface (12) of the round stock (10) consisting of a metallic material, in particular of chromium or steel, for example of hardened steel, chromium-plated steel or stainless steel. In order to improve this method such that disadvantages and shortcomings are avoided, the method includes the following steps: placing on the surface (12) at least one cover (20) which is adapted to the shape of the surface (12) and in particular has the inscription and/or marking (16), such that the region to be provided with the inscription and/or marking (16) is not covered by the cover (20),—exposing the round stock (10) to a first electrolyte (30) together with the cover (20), material being removed from the surface (12) by said electrolyte in the region to be provided with the inscription and/or the marking (16) while producing depressions (14), and—exposing the round stock (10) together with the cover (20) and the depressions (14) not covered by the cover (20) to a second electrolyte (32) by which the depressions (14) are filled to produce the inscription and/or marking (16) which differs from the surface (12) optically, in particular with respect to color. The present invention also relates to round stock (10) which is manufactured from a metallic material, with the round stock being provided with a correspondingly produced inscription and/or marking (16).
