    摘要: Steel sheet having a composition of ingredients containing substantially, by mass %, C: 0.005 to 0.200%, Si: 2.50% or less, Mn: 0.10 to 3.00%, N: 0.0100% or less, Nb: 0.005 to 0.100%, and Ti: 0.002 to 0.150% and satisfying the relationship of Ti−48/14×N≧0.0005, having a sum of the X-ray random intensity ratios of the {100} orientation and the {110} orientation of a ⅙ sheet thickness part of 5 or less, having a sum of the maximum value of the X-ray random intensity ratios of the {110} to {110} orientation group and the X-ray random intensity ratios of the {211} orientation of 5 or more, and having a high rolling direction Young's modulus measured by the static tension method and a method of production of the same are provided.
