Abstract: After a last patenting operation at a first diameter d1 a steel wire is (a) drawn by means of a lubricant to an intermediate work hardened state at an intermediate diameter d2, (b) coated at said intermediate diameter d2 and work hardened state with a brass alloy, (c) drawn at said intermediate diameter d2 and work hardened state to a final diameter df. This process may increase the ultimate tensile strength of the steel wire and may reduce the frequency of fractures during the drawing operation. The process also may provide steel wires with an improved adhesion to rubber.
