The steel wire rod contains oxides which comprises, on the weight % basis, SiO2, 70% or more; CaO + Al2O3, less than 20%; and ZrO2, 0.1 to 10% in the average composition of oxides of 2 mu m or more in width on a longitudinal section thereof. This wire rod is excellent in cold workability such as drawability, and steel wires which have high fatigue strength can be produced from this wire rod as stock steel. |
