    摘要： Al-killed steels containing 0.001-0.01% C., not larger than 1.5% Mn, 0.005-0.20% Al, not larger than 0.007% N and B in amounts determined by the ratio of B/N ranging from 0.5 to 2.5, and optionally containing not less than 1% Si and 0.04 to 0.12% P are subjected to ordinary hot and cold rolling operations, then soaked in a temperature range of from 730.degree. C. to A.sub.3 point by a continuous annealing process, and rapidly cooled from a temperature between the soaking temperature to 450.degree. C. down to a temperature not higher than 250.degree. C. at an average cooling rate not less than 60.degree. C./second, without subsequent overageing treatments, to obtain deep-drawing, non-ageing cold rolled steel sheets and strips having excellent press formability and paint bake-hardenability.
