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.

Method for producing a corrosion-resistant steel sheet

The invention relates to a method for producing packaging steel consisting of a cold-rolled steel sheet made of unalloyed or low-alloy steel having a carbon content of less than 0.1%. In order to provide high-strength packaging steel that has good formability and high corrosion resistance and can be produced in as energy-saving a manner as possible, the steel sheet according to the invention is first coated with a metallic coating and then annealed in a recrystallizing manner at a heating rate of more than 75 K/s and preferably more than 100 K/s to temperatures of more than 700&#xb0; C., such that the metallic coating melts. The coated and annealed steel sheet is then quenched to normal temperature at a cooling rate of at least 100 K/s.
