METHOD FOR THE PRODUCTION OF A STEEL SHEET FOR PACKAGING WITH A MULTILAYER CRYSTALLISATION STRUCTURE AND STEEL SHEET WITH A MULTILAYER CRYSTALLISATION STRUCTURE

The invention relates to a method for producing a steel sheet with a multilayer crystallisation structure, and a steel sheet, in particular for packaging, with a thickness of preferably less than 0.5 mm and a carbon content, relative to the weight, of 10 to 1000 ppm, and a nitrogen content, averaged...

Zusammenfassung:	The invention relates to a method for producing a steel sheet with a multilayer crystallisation structure, and a steel sheet, in particular for packaging, with a thickness of preferably less than 0.5 mm and a carbon content, relative to the weight, of 10 to 1000 ppm, and a nitrogen content, averaged over the thickness of the steel sheet, of more than 50 ppm, as well as a multilayer crystallisation structure with a core region and a near-surface region surrounding the core region on both sides, wherein the near-surface region is at least substantially recrystallised and the core region is not or at least not entirely recrystallised.
