Abstract
An object of the present invention is to provide a cold-rolled steel sheet having such excellent deep drawability as to allow good formability to be realized in actual press forming, as well as an advantageous manufacturing method of the cold-rolled steel sheet. Specifically, the present invention provides a high strength cold-rolled steel sheet having excellent deep drawability, comprising a composition including by mass%, C: 0.005% or less, Si: 0.1% to 0.8%, Mn: 1.0% to 2.5%, P: 0.1% or less, S: 0.02% or less, N: 0.01% or less, Al: 0.1% or less, at least one type of element selected from Ti: 0.005% to 0.05% and Nb: 0.01% to 0.08%, and the remainder consisting of Fe and incidental impurities, wherein gain diameter of ferrite is at least 7?rn, ratio oflength of ferrite grain in the rolling direction with respect to length of ferrite grain in the sheet thickness direction is 2.5 or less, and proportion of high-angle grain boundary, at which crystal misorientation between two crystals facing each other with a.grain boundary therebetween is at least 15?, is 50% or more in the entire ferrite grain boundaries.
