Abstract (en)

A method is taught for processing low carbon steel wire (10) into high carbon steel wire having improved characteristics for use in vehicle tire construction and other applications, including increased wire strength, corrosion resistance and rubber adherence. Low carbon steel wire is carburized to raise carbon content, resulting in increased strength and corrosion resistance. According to other aspects of the invention, the carburization process may occur in the presence of rubber adherence agents (23), which adhere to the steel wire (10), resulting in improved steel rubber adherence in a single processing step.
