    • Disclosed is a stainless steel filament made of a two-phase stainless steel having two-phase of austenite and ferrite, which is used as a PC tension material being a standing wire and as a wire rope being a running wire. The stainless steel filament contains 0.01-0.10 wt% of C, 0.1-1.0 wt% of Si, 0.30-1.50% of Mn, 0.010-0.040 wt% of P, 0.001-0.030 wt% of S, 18.0-30.0 wt% of Cr, 3.0-8.0 wt% of Ni, 0.1-3.0 wt% of Mo, and 0.10-0.45 wt% of N, the balance being essentially Fe and inevitable impurities, wherein the volume ratio of the ferrite amount to the sum of the austenite amount and the ferrite amount is specified to be in the range from 20.0 to 80.0%. Upon drawing, the drawing draft is in the range from 40 to 97%, the average aspect ratio (M R value) is in the range from 4 to 20, and the aging temperature is in the range from 150 to 750 °C.
