PURPOSE: A copper-containing austenite stainless steel plate and a method for manufacturing the same are provided to obtain superior gain corrosion resistance through short-time annealing at low temperatures. CONSTITUTION: A method for manufacturing a copper-containing austenite stainless steel plate comprises the steps of: preparing a stainless steel plate containing copper of 1wt%-5wt%(S10), cold rolling the stainless steel plate(S20), annealing the stainless steel plate(S30), and repeating the cold rolling and annealing steps while gradually raising the annealing temperature(S40). In the initial cold rolling, the reduction ratio of the stainless steel plate is 3%-15%. The reduction ratio of the stainless steel plate after final rolling is 70%-90%. |
