Abstract

An untempered steel material comprises a steel component comprising in mass% 0.20 to 0.60% of C 0.50 to 2.0% of Si 0.20 to 2.0% of Mn 0.010 to 0.15% of P 0.010 to 0.15% of S 0.10 to 0.50% of V 0.002 to 0.02% of N and a remainder made up by Fe and impurities wherein the segregation ratio of V is 1.0 or more and less than 3.0 in which the segregation ratio of V is the ratio of the maximum value among the concentrations of V in the steel material to the average value of the concentrations of V in the steel material as measured in a cross section of the steel material.
