Abstract

The invention relates to a method of manufacturing strips and sheets of stainless steel. The strips are in a first step subjected to an electrochemical pickling, the oxides from the annealing being removed. Subsequently, those metal surface layers, which have been dechromed during the annealing, are removed through a pickling operation, wherein the surface layers are roughened. The strips, from which oxides and defective surface layers have been removed, subsequently in a third step are subjected to an alternatingly anodic and cathodic treatment, resulting in a neutralization and a slight removal of the protruding peaks of the microprofile of the steel surface, which has been magnified during the preceding step. Finally, the strips are roller straightened between bright rolls.
