摘要：
According to the present invention, a strength of 120 to 200 kgf/mm.sup.2 in terms of 0.2% yield point and optionally a spring critical value of 55 to 150 kgf/mm.sup.2 are imparted to a high-strength stainless steel foil for corrugation by subjecting a thin sheet of a stainless steel comprising an alloy composed mainly of 10 to 40% by weight of Cr and 1 to 10% by weight of Al to final cold rolling and optionally subjecting the cold-rolled sheet to an aging treatment at a temperature in the range of from 80.degree. to 500.degree. C. after the completion of the final cold rolling. This enables corrugation to be effected at a high corrugation rate of 10 m/min or more.
