Abstract
The invention relates to a metal strip which is produced from steel by hot rolling and by cold rolling of the metal strip. The invention also relates to a blank produced from the metal strip, the use of the metal strip, and to a method of producing it. The object of providing metal strip from which components of minimum weight which are adapted to specific loads can be produced with little cost or complication is achieved by metal strip of the generic kind which, after the cold rolling, is of constant thickness and has, section by section, regions whose mechanical properties vary. What 'after the cold rolling' means, for the purposes of the present invention, is that, immediately on completion of the cold rolling, i.e. without any further treatment such as heat treatment, regions whose mechanical properties vary are present in the metal strip.
