ABSTRACT:
A method of manufacturing a steel wire with high tensile strength having improved bending and torsional ductility properties useful as a reinforcement wire or cord, especially for rubber products such as tires, comprising providing steel comprising less than 0.015%, preferably less than 0.010%, and most preferably less than 0.008% by weight sulfur and drawing said steel beyond normal drawing limits into a wire having a tensile strength in N/mm.sup.2 of at least 2250-1130 log d where d is the wire diameter in millimeters, and optionally, depositing a covering layer of rubber adherable material such as brass on the drawn wire.
