Abstract

PURPOSE:To develop a setting wire which has excellent wear resistance, toughness and heat resistance and is light in weight by subjecting a steel wire to a carburization treatment then to a diffusion treatment, thereby forming a chromium carbide layer on the wire at the time of producing the setting wire for a dot impact type setting head. CONSTITUTION:The wire rod made of a high-carbon hard steel as a stock for the setting wire is embedded into powdery carbon and is heated for 2hr at, prescribed 1,000 deg.C by which the surface of the wire rod is carburized and the carbon content is increased to 1.2-1.5wt.%. This wire is embedded into the powder mixture composed of 10:1 powder of Cr and powder of ammonium chloride as a catalyst and is subjected to a heating treatment for 0.75hr at, prescribed 1,000 deg.C to diffuse Cr into the steel wire and to form the hard chromium carbide layer on the surface of the steel wire at about 10mum thickness, by which the carbon content of the steel wire is decreased to 0.6-1.0wt.%. Such wire is subjected to hardening and tempering treatments and is used as the wire for the setting head of a dot impact type.
