ABSTRACT:
The steel wire is made using a carbon steel wire rod material containing 0.70 to 0.75 wt % carbon and has the characteristics that its diameter is (N/mm.sup.2), d: diameter (mm)!. Furthermore, the torque decrease factor of the steel wire is less than 7% in a torsion-torque curve in a torsion-torque test wherein forward twisting and then reverse twisting are applied. A preferred steel cord has two steel wires bundled together substantially in parallel and one steel wire is wound around this bundle. This steel cord is made from steel wires having the diameter, tensile strength and toughness characteristics set forth above, and also the ratio B/A of the strength B of the twisted steel cord to the aggregate strength A of the steel wires before they are twisted together into the steel cord is 0.935 or over.
