Abstract
A wire strand is made by helically winding a number of layers of steel wire around a steel king wire. The wires in such layers are made from a first steel grade while the king wire is made from a second steel grade. In addition, the outermost layer of wire in the strand may be made from a third steel grade. A wire rope is formed by helically winding a number of such wire strands around a wire core.
