<p>Magnetic metal sheet obtained from a hot-rolled steel strip containing especially iron, silicon and aluminium and forming part of a class of sheets with oriented grain, characterised in that its composition is the following: silicon lower than 3.3%, aluminium between 1.5 and 8%, in concentration by weight, and in that the steel strip is subjected to cold rolling in two stages with a final reduction ratio of between 50 and 80%, the magnetic sheet obtained having a general texture of cubic type, at least 40% of the grain not departing by more than 15 DEG from the ideal cubic orientation (100) [001] in Miller's notation.</p> |
