Abstract: Strands and wire ropes composed of materials such as high carbon steels and stainless steels can be provided in a compacted, mechanically stress relieved and thermally stress relieved condition. The wires are compacted during stranding to form the individual strands of the wire ropes. The wires can be thermally stress relieved prior to stranding to remove tensile residual stresses. Compaction produces a compressive residual stress state in the strands which increases fatigue resistance. The strands can be thermally stress relieved subsequent to closing. The wires and strands can be heated using a process such as induction heating. The wire ropes can be torque balanced or rotation resistant. The wire ropes have high strength, a high strength-to-weight ratio and enhanced fatigue life. Stainless steel wire ropes also provide corrosion resistance.
