摘要： High performance high carbon wire with refined inclusions after wire rolling, extremely low wire breakage rates at the time of drawing even in tough applications, and excellent in fatigue characteristics after wire drawing, characterized by having a predetermined composition of ingredients and in that the number ratio of inclusions satisfying (%SiO 2 )=40 to 95%, (%can)=0.5 to 30%, (%Al 2 O 3 )=0.5 to 30%, (%MgO)=0.5 to 20%, and (%MnO)=0.5 to 10% and further satisfying (%Na)=0.2 to 7% and (%F)=0.17 to 8% (below, referred to as "inclusions covered due to composition") in the oxide-based nonmetallic inclusions of a short axis of 0.5 µm or more, a long axis of 1.0 µm or more, and a circle equivalent diameter (area converted to diameter) of 1 µm or more which are seen in the L direction cross-section of the wire (below, referred to as "inclusions covered due to size"), that is, the number of inclusions covered due to composition/number of inclusions covered due to size×100, is 80% or more.
