Abstract (en)
[origin: EP3282027A1] To provide a high-carbon steel wire rod with excellent wire drawability. The high-carbon steel wire rod of the present invention includes predetermined components and also includes pearlite and proeutectoid cementite, and an area ratio of pearlite is 90% or more relative to the entire structure, a maximum length of proeutectoid cementite is 15 µm or less, and a concentration difference between an average of the Si concentration inside proeutectoid cementite and a maximum value of the Si concentration inside ferrite that forms a lamellar structure of pearlite is 0.50 to 3%.
