Abstract
Provided are a cold-rolled steel plate having excellent post-aging moldability and shape retention, and a method for producing same. The steel plate has a ferrite-phase based structure comprising 0.01 to 0.05% 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, no more than 0.005% N, with the remainder being made up of iron and inevitable impurities. The average particle size of said ferrite phase is 10 to 20μm, and the standard deviation σ<sub>A</sub> of the natural logarithm of the value obtained by dividing individual ferrite particle sizes by the average value is at least 0.30. In order to obtain the steel plate, when carrying out annealing after cold rolling, heating from 600℃ to the range of the holding temperature at an average heating rate of 1 to 30 30°C/s; holding is carried out at a holding temperature of 800 to 900°C for a holding time of 30 to 200s; cooling from the holding temperature to the range of 550°C is carried out at an average cooling rate of 3 to 30°C/s; after which the steel plate is maintained at a temperature of 500 to 300°C for at least 30s, and strain is applied to give an elongation of 0.5 to 2.0% at room temperature.
