Abstract
A process of producing cold rolled stainless steel strip, according to the invention, includes preliminary treatment for hot rolled stainless steel strip, in which preliminary treatment, hot rolled stainless steel strip is, at first, treated through annealing and picking process and is subsequently subject cold rolling without introducing rolling mill lubricant at a reduction of more than 5%. The process of preliminary treatment for preparation of cold rolling is useful for producing high surface brightness cold rolled stainless steel strip, which can achieve both of satisfactory quality and high efficiency.
