摘要： Disclosed is a stainless steel wire made of a two-phase stainless steel having austenite and ferrite, which is used as a PC tension member and wire rope both for dynamic and static use. The stainless steel wire 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 to the sum of the austenite and the ferrite 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 mean slenderness ratio (M.sub.R value) is in the range from 4 to 20, and the aging temperature is in the range from 150.degree. to 750.degree. C. This stainless steel wire product provides a tension member suitable for tension members, hanging members and cables, that is high in tensile strength, elongation, fatigue strength, reduction of area, and torsion value, and low in relaxation value, and high in corrosion resistance. Moreover, provided is a stainless steel wire rope having corrosion resistance higher than wire ropes made of SUS304 and SUS316 and a fatigue strength higher than high carbon steel wire ropes, which is applicable for either dynamic or static use.
