A non-oriented magnetic material consisting essentially of </=0.065% C, </=0.10% Al, 0.31 to 3.15% Si, </=0.020% O, </=0.01% N and B present in such amounts that the ratio of B/N is in the range of 0.5 to 2.50. The non-oriented magnetic material of this invention is produced by hot rolling a material of the above composition, subjecting the hot-rolled sheet to at least one cold-rolling step with intermediate annealing followed by a continuous annealing step and optionally a reannealing step to produce a non-oriented magnetic material. |
