ABSTRACT:
This invention relates to steel wires and steel cords used as a reinforcement for rubber articles such as pneumatic tire, industrial belt and the like, particularly steel wires and steel cords having an excellent adhesion property to rubber, in which an amount of phosphorus included as an oxide in a surface layer region from a brass plated surface applied to a circumferential face of a wire up to a depth of 5 nm in a radial direction of the wire is controlled to not more than 1.5 atomic %, whereby an excellent adhesion property between steel cord and coating rubber can be provided even when an adhesion promoter conventionally added in a coating rubber composition for the steel cord is reduced or is not added.
