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), and wherein the steel sheet is annealed after rolling, then provided with a metallic corrosion protection layer and subsequently tempered. 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 sheet. 本发明涉及一种生产钢板的方法，特别是用于车辆的外壳板，其中，将具有所需组成的钢合金熔炼、浇注、然后轧制形成钢板，其中所述钢合金是"无间隙原子"钢(IF钢)且钢板在轧制后退火，随后设置金属防腐保护层，然后回火。为了实现具有最窄分散的低Wsa值，将铌合金化进钢板，其含量为＞0.01wt.％，优选＞0.011wt.％。
