Abstract

Procédé comprenant une seule étape de traitement thermique d'alliation d'une tôle galvanisée, caractérisé en ce que: - la température maximale atteinte par la bande lors dudit traitement est supérieure ou égale à 490.degree.C, - ladite température maximale et la durée du traitement sont limitées de manière à ce que la teneur moyenne en fer dans le revêtement allié obtenu ne dépasse pas 6 g/m2. Application aux aciers emboutissables sans intersticiels. La tôle obtenue résiste à la fois au poudrage et à l'écaillage.
