The remainder being iron and impurities resulting from the elaboration, according to which a strip obtained by hot rolling is cold-rolled in order to obtain a cold-rolled strip with a thickness of less than 0.6 mm.

After cold rolling, a continuous annealing treatment is carried out by passing into a continuous oven, at a temperature comprised between the order/disorder transition temperature of the alloy and the onset temperature of ferritic/austenitic transformation of the alloy, followed by rapid cooling down to a temperature below 200 C. Strip obtained.
