Abstract

A method for producing a corrosion-resistant steel sheet made of an unalloyed or low-alloy and cold-rolled steel having a carbon content of less than 0.1 wt %. The method includes the following steps: applying a metal coating to the steel sheet; annealing the coated steel sheet in a recrystallizing manner by heating the coated steel sheet to temperatures in the recrystallization range by electromagnetic induction in an inert-gas atmosphere; and quenching the coated and annealed steel sheet. The metal coating is fused on during the recrystallization annealing.
