Abstract
The invention relates to a method for producing a coated steel strip for producing tailored blanks suitable for thermomechanical shaping. The method includes the following steps: providing a hot-rolled steel strip; coating the strip with a metallic coating; cold rolling the strip such that the strip obtains a variable thickness in its length direction, having at least thicker sections and thinner sections, such that tailor rolled blanks (TRBs) can be cut from this strip. The invention also relates to a steel strip thus produced and the use of such a steel strip.
