Abstract

Provided are a wire rod, etc. for which spheroidize annealing and quenching/tempering heat treatment steps can be omitted. The wire rod has a specified chemical composition. In area ratio, at least 90% of the metal structure is bainite. The average bainite block grain diameter in the surface layer measured in a transverse cross-section is 15 µm or less. The ratio between the average bainite block grain diameter in the surface layer measured in a transverse cross-section and the average bainite block grain diameter measured in the center section is less than 1.0, and the average grain diameter of cementite dispersed in the bainite is 0.1 µm or less.
