Production of thin ferritic stainless steel sheet having excellent workability

Abstract

Abstract PURPOSE:To obtain a thin ferritic stainless steel sheet having excellent processability in a simplified stage, by subjecting a ferritic stainless steel slab contg. limited amts. of Al and C to a specific heat treatment after rough rolling then subjecting the same to post finish rolling. CONSTITUTION:A ferritic stainless steel slab contg. 0.08-0.5% Al and 0.03- 0.1% C is heated to >=950 deg.C and is roughly rolled. The resultant rough-rolled slab is heated and held within 10min in a 900-1,100 deg.C temp. range; thereafter the slab is subjected to finish rolling with a continuous finishing mill then to hot rolling followed by cold rolling, whereby the thin ferritic stainless steel sheet having excellent processability is produced in the simplified production stage contg. no box annealing.
