PROBLEM TO BE SOLVED: To provide a ferritic stainless steel wire manufacturing method for manufacturing a product having cold workability substantially not different from that of conventional heat-treated products even when the heat treatment after rolling the wire is omitted and the manufacturing cost is reduced. SOLUTION: Wires of ferritic stainless steel containing≤0.10% C are rolled at a temperature equal to or lower than theγtransformation point but≥700°C, and gradually cooled at a cooling rate of 0.3°C/sec. (the temperature transition as shown by the plot of black squares in the figure). Thus, rolling is completed while avoiding deposition of martensite, and production of a Cr-depleted layer can also be avoided. As a result, a flexible wire product can be obtained, in which the tensile strength is reduced, and the drawing value is enhanced. COPYRIGHT: (C)2005,JPO&NCIPI
