PURPOSE:To provide desired mechanical properties to a cold rolled austenitic stainless steel sheet without requiring temper rolling by cold rolling a steel plate to a prescribed thickness and heat treating it at a specified temp. CONSTITUTION:A hot rolled austenitic stainless steel plate is cold rolled to the thickness of an end product at 20-80% draft, and the cold rolled steel sheet is heat treated at 750-950 deg.C. By this method a steel sheet with desired strength and ductility can be obtd. without carrying out temper rolling. Accordingly, the occurrence of defects in the shape of the steel sheet due to conventional temper rolling can be prevented, and the removal of adhered rolling oil can be made unnecessary. |
