Abstract

The steel strip is produced by hot strip-rolling, cold-rolling, recrystallising annealing and subsequent dressing. To be able exclusively to use continuous production processes having improved economics and at the same time to obtain improved properties of the finished products, differentiated according to the particular deformation processes, material loadings and parameters, it is proposed according to the invention to cast steels (data in percent by mass) having max. 0.06% C max. 0.10% Si max. 0.40% Mn max. 0.03% P max. 0.03% S max. 0.01% N at least one of the five elements from the following group 0- 0.10% Al 0- 0.006% B 0- 0.20% Ti 0 -0.20% Nb 0 -0.20% V impurities due to the smelting, the remainder being iron, to give ingots, to heat these before hot-rolling to a temperature of at most 1200 DEG C, to roll them out, reel them and then to recrystallisation- anneal them to yield strengths of not more than 200 N/mm<2>.
