摘要： A method for manufacturing an alloy sheet comprising the steps of: (a) hot-rolling a slab containing Fe, Ni and Cr into a hot-rolled strip; (b) annealing the hot-rolled strip at a temperature of 810.degree. to 890.degree. C.; (c) cold-rolling the annealed hot-rolled strip at a reduction ratio of 81 to 94% into a cold-rolled sheet; (d) recrystallization annealing of the cold-rolled sheet; (e) finish cold-rolling the cold-rolled sheet subjected to the recrystallization annealing at a reduction ratio of 14 to 29%; (f) stress relief annealing of the cold-rolled sheet subjected to the finish cold-rolling; and (g) annealing, before press-forming. The cold-rolled sheet subjected to the stress relief annealing at a temperature of 740.degree. to 900.degree. C. for 2 to 40 minutes and satisfying the following equation: T.ltoreq.-123 logt+937, where T is a temperature (.degree.C.) and t is a time (minutes) for the annealing.
