Abstract (en)
[origin: EP3604590A1] A wire rod according to an aspect of the present invention includes a predetermined chemical composition, in which an average value of a compositional ratio ε of a complex oxide satisfies 0.00 ≤ ε < 3.00, measured in a central portion, and an average value of an equivalent circle diameter of the complex oxide is 6.0 µm or less, measured in the central portion. A flat steel wire according to another aspect of the present invention includes a predetermined chemical composition, in which an average value of a compositional ratio ε of a complex oxide satisfies 0.00 ≤ ε < 3.00, measured in a center portion, and an average value of an equivalent circle diameter of the complex oxide is 3.0 µm or less, measured in the center portion.
