Abstract

Provided are a cold-rolled steel plate having excellent moldability and shape retention, and a method for producing same. The plate contains, in mass %, 0.0010 to 0.0030% C, no more than 0.05% Si, 0.1 to 0.5% Mn, no more than 0.05% P, no more than 0.02% S, 0.02 to 0.10% Al, 0.0010 to 0.0050% N, and 0.010 to 0.035% Nb. Moreover, Al content and N content satisfy the relation stipulated in formula (1) below; Al content and N content satisfy the relation stipulated in formula 1, with the remainder being made up of Fe and inevitable impurities. The steel plate has a composition principally comprising ferrite particles having an average particle size of 8 to 20μm, and the surface ratio of ferrite particles on the plate surface within 15° from {211} is 50% of said structure. [%Al]/[%N]â §10ã (formula 1). [%M] represents the content of element M (mass %).
