Abstract

PURPOSE:To obtan a cold-rolled steel sheet having both of deep-drawability and baking-hardenability useful as a car part or the like, by recrystallization-annealing a low-carbon cold-rolled steel sheet having specified composition, to which Nb, V and/or Ti is added, in a continuous annealing process, and then overaging the steel sheet at a specified temperature. CONSTITUTION:A steel, comprising 0.008-0.020% C, 0.04-1.20% Mn, Si<=0.50%, P<=0.100%, 0.01-0.10% Al, 1XC%-5XC% of one or more of Nb, V and Ti, and the balance being Fe and inevitable impurities, is hot-rolled and cold-rolled. This cold-rolled steel sheet is then recrystallization-annealed in a continuous annealing process, and overaged at 500-200 deg.C. According to this method, a drawable Al-killed cold-rolled steel sheet, excellent in baking-hardenability, having properties such as delay ageability, is obtained.
