Abstract
After a last patenting operation at a first diameter d.sub.1 a steel wire is (a) drawn by means of a lubricant to an intermediate work hardened state at an intermediate diameter d.sub.2, (b) coated at said intermediate diameter d.sub.2 and work hardened state with a brass alloy, (c) drawn at said intermediate diameter d.sub.2 and work hardened state to a final diameter d.sub.f. 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.
