METHOD FOR PRODUCING STEEL SHEETS, STEEL SHEET, AND USE THEREOF

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 a bake-hardening steel (BH steel) and the steel sheet being annealed after the tolling and s...

Beschreibung
Zusammenfassung:	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 a bake-hardening steel (BH steel) and the steel sheet being annealed after the tolling and subsequently provided with a metallic anti-corrosion coating and then dressed, 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.
