Claim:
Wire for slickline, wireline or well-logging cable consisting of a ferrite-austenite duplex stainless steel alloy containing in percent by weight: C larger than 0 to max 0.03 Si max 0.3 Mn 0-3.0 Cr 24.0-30.0 Ni 4.9-10.0 Mo 3.0-5.0 N 0.40-0.45 B 0-0.0030 S max 0.010 Co 0.5-3.5 W 0-3.0 Cu 0-2.0 Ru 0-0.3 Al 0-0.03 Ca 0-0.010 remainder Fe and normally occurring impurities and additions, wherein the ferrite content amounts to 40-65 percent by volume, said steel having high strength both in hot worked condition as well as after cold working, good ductility and good structure stability, wherein a ratio of PRE in an austenite phase to PRE in a ferrite phase is 0.9 to 1.15 with at least one of PRE in the austenite phase and PRE in the ferrite phase is greater than 48, and wherein the alloy is free from sigma phase.
