The improved method is particularly characterized by a special annealing step in a continuous annealing furnace under the application of a tension not exceeding 2 kg/mm.sup.2 to a coiled alloy sheet to be annealed, the annealing including rapid heating of the coiled alloy sheet to a temperature of 400.degree. to 500.degree. C. at a heating rate exceeding 50.degree. C./min.
