PURPOSE:To produce a ferritic stainless steel sheet having exellent workability by ending the finish rolling in a hot rolling stage at a high temp. and cold rolling the hot rolled seet without annealing. CONSTITUTION:Finish rolling in a hot rolling stage in a process for producing a ferritic stainless steel sheet by cold rolling without annealing of a hot rolled sheet is ended at >=850 deg.C to remove a heterogeous deformation zone, by which the ferritic stainless steel sheet having good deep drawability is obtd. A 430 steel contg. about 0.03-0.08% C, about 0.02-0.1% Ti, and about 0.06-0.2% Al is suitable when the raw material for which the above-mentioned method is applied is intended for deep drawing. An ordinary 430 steel added with about 0.08-0.2% Al is suitable when said material is intended for light working.
