摘要： PROBLEM TO BE SOLVED: To obtain a steel print wire for dot printer in which the rust resistance is enhanced by regulating the surface roughness at a specified level or below on the outer circumference of shaft part. SOLUTION: A long quenched/tempered wire member is cut into a length corresponding to a product and a main polishing medium is abraded by dry barrel polishing method employing an organic medium, e.g. nut particles or corns thus producing a steel print wire for dot printer having surface roughness of 0.30μm Rmax or below on the outer circumference of shaft part and excellent in rust resistance. It is polished such that less than six hole-like black dots having diameter of 1.5mm or above are present per 100cm of the outer circumferential surface at shaft part on the photograph taken by a scanning electron microscope (acceleration voltage 15kV, magnification 1000). Holes made in the wire surface due to missing of carbide are reduced in size and depth thus reducing the substance being captured therein and rust resistance is enhanced greatly by removing the surface oxide.
