Abstract

PURPOSE:To produce the titled steel sheet excellent in workability by a simplified process, by a method wherein a ferritic stainless steel slab contaning solAl and at least one element selected from the group consisting of S, Ti, Nb and the like is hot rolled, directly followed by cold rolling, and then it is subjected to final annealing. CONSTITUTION:A ferritic stainless steel slab containing 0.08-0.5% of solAl and at least one member selected from the group consisting of 2-50ppm of B, 0.005- 0.4% of Ti, 0.005-0.4% of Nb, 0.005-0.4% of V and 0.005-0.4% of Zr is not rolled in the ordinary conditions to produce a hot-rolled steel strip. Then, without annealing the hot-rolled steel strip, it is directly subjected to a single run of cold rolling to produce a steel sheet of a thickness, for example, of 0.7mm. and the sheet is subjected to the final annealing, namely, recrystallization appealing. As a result, a ferritic stainless steel sheet greatly improved in workability such as deep-drawability can be obtained.
