Abstract
The fine steel wire according to the present invention has a high strength and high toughness, which is used as a rubber reinforcing material for a belt cord or tire cord, or as missile wires. Such a fine steel wire can be obtained by drawing a wire rod for a fine steel wire properly adjusted in its composition and structure, while applying working strain such that the total reduction of area in the final wire drawing step becomes 95% or more.
