Abstract
A multilayer flat steel product may include a multitude of mutually bonded steel alloy layers. A steel of a first steel alloy may be provided in at least one of the steel alloy layers, and a steel of a second steel alloy different than the first steel alloy may be provided in at least one of the other steel alloy layers. The steel of the first steel alloy may have high strength, and the steel of the second steel alloy may have lower strength and lower carbon content. To enable function-optimized modelling of local material properties in all directions, at least one steel of the first steel alloy and at least one steel of the second steel alloy may be present at least within one layer of the flat steel product. Further, a component, such as for a motor vehicle body, may be comprised of a corresponding flat steel product.
