A method for producing steel sheets, in particular for body shell sheets of vehicles, in which a steel alloy of a desired composition is melted, poured, and then rolled into sheet form, the steel alloy being an interstitial free steel (IF steel) and after the rolling, the steel sheet being annealed and dressed and then provided with a metallic anti-corrosion coating by means of an electrolytic process or by means of vapor deposition, wherein in order to achieve a low Wsa value with the narrowest possible spread, a niobium content of >0.01% by weight, preferably >0.011% by weight, is added to the alloy of the steel.
