Abstract (en)
The present invention provides a hot rolled wire rod having high strength and excellent SSC resistance. Disclosed is a hot rolled wire rod including, in percent by mass: C: 0.20 to 0.5%, Si: 0.05 to 0.3%, Mn: 0.3 to 1.5%, Al: 0.001 to 0.1%, P: exceeding 0% and 0.01% or less, and S: exceeding 0% and 0.01% or less, with the balance being iron and inevitable impurities. When the sulfur content in the hot rolled wire rod is measured at 300 sites or more at intervals of 200 µm using an electron beam microanalyzer, a segregation ratio (S max /S ave ) is 30 or less, where a segregation ratio is defined as a ratio of the maximum sulfur content S max (% by mass) to an average sulfur content S ave (% by mass).
