Construction and Manufacture of Steel Wire Rope

Specification and Tests of Rope Wire Chemical Analysis: The range in composition of steel used in the manufacture of wire rope is as follows: Carbon 0 4 to 0.9 per cent Manganese 0 4 to 0.8 Sulphur Not above 0.04 Phosphorus Not above 0.04 The carbon and manganese content are varied according to the gauge of wire to be drawn and the tensile strength required. Generally speaking, best results are obtained from heats where the melt is not of too large a tonnage. The amount of reduction and patenting of the wire is left to the wire maker, who thus has a free hand in meeting the balance of the specification.
