PURPOSE:To obtain the titled steel sheet or strip having a low plastic anisotropy, by omitting annealing treatment of hot rolled plate between hot and cold rolling processes and applying cold rolling thereafter under a suitable condition. CONSTITUTION:Cold rolled steel sheet or strip of austenitic stainless steel is manufactured through hot and cold rolling processes and final annealing process. The hot rolling process is carried out under a condition in which hot rolled plate having recrystallization structure is obtd., and annealing treatment of hot rolled plate between hot and cold rolling processes is omitted. The plate is cold rolled to product sheet thickness without applying intermediate annealing in cold rolling process. Further, total cold rolling draft therein is regulated to <40%. |
