Abstract

L'acier selon l'invention se distingue en ce qu'il contient essentiellement en poids 0,02 à 0,06 % de carbone, 0,015 à 0,15 % de manganèse, 0,01 à 0,05 % de matière du groupe constitué par le soufre et le sélénium, 0,0006 à 0,0080 % de bore, jusqu'à 0,1 % d'azote, 2,5 à 4,0 % de silicium, 0,3 à 1,0 % de cuivre, au plus 0,008 % d'aluminium, le reste étant du fer, la bande laminée à chaud ayant une épaisseur de 1,25 à 3 mm et la bande laminée à froid ayant une épaisseur ne dépassant pas 0,5 mm, la caractéristique principale étant la quantité commandée de cuivre. Un tel acier convient en particulier pour les circuits magnétiques.
