Abstract (en)
A cold-rolled steel sheet having excellent toughness is provided. The cold-rolled steel sheet has a defined chemical composition, an average particle size of 0.10 µm or more of carbides containing at least one of Nb, Ti, and V in ferrite grains, and a number density of 100/mm<sup>2</sup> or more of the carbides having a particle size of 0.10 µm or more.
