Abstract (en)
[origin: EP3056580A1] A wire rod according to the present invention includes a predetermined chemical composition, wherein a metal structure includes 90 area% to 100 area% of bainite, wherein when eight test pieces having a length of 400 mm, which are obtained by dividing a wire rod having a length of 3200 mm into eight components having a same length, are manufactured, an average tensile strength TS of each test pieces satisfies a relation of "[TS]‰¤810×[C]+475" by N/mm 2 , wherein a difference between a maximum value and a minimum value of the tensile strengths of each test pieces is 50 N/mm 2 or less, and wherein an average reduction of area RA of each test pieces satisfies a relation of "[RA]‰¥-0.083×[TS]+154" by %.
