Abstract

L'invention concerne une méthode d'obtention de tôles présentant après soudage une excellente résistance à la corrosion feuillante. Elle consiste à appliquer la gamme de transformation du brevet principal comportant une homégénéisation de la plaque coulée, un laminage à chaud se terminant à une temperature supérieure à 370 degrés C, un refroidissement rapide à l'ambiante, un laminage à froid, puis un traitement de courte durée à 200 degrés C-380 degrés C, à un alliage de composition légèrement différente, dans lequel les teneurs en chrome et en manganèse sont abaissées. L'invention s'applique aux tôles destinées à être assemblées par soudage.
