Estimating the term…
A flat steel product for producing a steel component by hot forming includes a steel substrate, which consists of a steel having 0.1-3 wt. % Mn and optionally up to 0.01 wt. % B, and an aluminum-based anticorrosion coating deposited on the steel substrate, and an absorption layer including carbon particles is arranged on the anticorrosion coating. A method is disclosed for producing a flat steel product, and to the use of carbon particles in an absorption layer on a flat steel product coated with an aluminum-based anticorrosion coating in order to reduce the reflectivity in the infrared region. A method is disclosed for producing a steel component from a flat steel product.
