摘要

A cold-rolled steel sheet containing: in mass %, C: 0.0005 to 0.0045%; Mn: 0.80 to 2.50%; Ti: 0.002 to 0.150%; B: 0.0005 to 0.01%, in which (1) Expression is satisfied, and a balance being composed of iron and impurities, in which at the position of ¼ thickness of a sheet thickness, a random intensity ratio (A) of the {332}110 orientation is 3 or less, a random intensity ratio (B) of the {557}9 16 5 orientation and a random intensity ratio (C) of the {111}112 orientation are both 7 or more, and {(B)/(A)≧5} and {(B)(C)} are satisfied.
