The invention relates to a method for producing band-shaped steel for components which are produced by drawing and ironing. The invention also relates to a steel band which can be drawn or ironed and which has been produced by the inventive method. The hot strip is cold-worked in one or mor e steps at a ratio of the cold roll of at least 86 %. Furthermore, at least on e side of the band material is provided with a galvanically produced coating containing Ni, Co, Cu, Fe, Sn, In, Pd, Bi and/or the alloys thereof or with a roll-bonded coating containing Cu and/or brass and/or the alloys thereof. Th e aim of the invention is to carry out the inventive method with the fewest processing steps possible and with low production costs. The method therefor e comprises the steps: etching, cold rolling in one or two steps, annealing th e coiled band (coil-annealing), optionally rerolling the band. The hot strip preferably contains boron with a percentile of 0.0013 and 0.0060 percent by weight, whereby the weight ratio of boron to nitrogen amounts to 0.5 to 2.5. |
