Abstract
PURPOSE: To produce the cold rolled steel sheet having tensile strength above 100 kg/mm2 and an excellent workability, by making contain Mn, Nb, Ti, etc. to the steel as the elements for improving the strength and by carrying out the heat treatment at a temperature below the recrystallization temperature and under the Ac1 transformation point.
