METHOD FOR PRODUCING STEEL SHEETS, STEEL SHEET AND USE THEREOF

The invention relates to a method for producing steel sheets, in particular for outer skin sheets of vehicles, wherein a steel alloy of a desired composition is melted, cast and then rolled to a steelsheet, said steel alloy being an Interstitial Free steel (IF steel), wherein the steel sheet is annealed and tempered after rolling, and is subsequently provided with a metallic corrosion protectionlayer by means of an electrolytic method or by evaporation. In order to achieve a low Wsa value with the most narrow scattering, niobium having a content of >0.01 wt.%, preferably >0.011 wt.% is alloyed to the steel. 本发明涉及用于生产钢板的方法，特别是用于车辆的外壳板，其中，具有所需组成的钢合金被熔炼、浇注，然后轧制成钢板，所述钢合金是无间隙原子钢(IF钢)，且所述钢板在轧制后退火和修整，并然后借助电解方法或蒸镀提供有金属防腐层。为了实现有具有最窄扩展的低Wsa值，将含量为按重量计＞0.01％、优选地按重量计＞0.011％的铌合金化到钢。
