abstract |
The present invention relates to a multilayer flat steel product (1) composed of a plurality of steel alloy layers (2, 3a, 3b, 4a, 4b) connected to each other, and the steel alloy layers (2, 3a, 3b, 4a, 4b) In at least one, a steel of a first steel alloy is provided and a second steel different from the first steel alloy in at least one of the other steel alloy layers (2, 3a, 3b, 4a, 4b) An alloy steel is provided, wherein the first steel alloy steel is a high strength steel and the second steel alloy steel is a low strength steel and contains a low proportion of carbon. In order to allow functional optimization modeling of local material properties in all directions, the present invention provides at least one steel and a first steel alloy of the first steel alloy in at least one layer (plane of the metal sheet). It is proposed to provide at least one steel of two steel alloys. The invention also relates to a component (5) consisting of a corresponding flat steel product (1), in particular for the vehicle body. |
