Abstract
PURPOSE: To manufacture a soft cold rolled steel plate with superior deep drawability and bulgeability at a low coiling temp. by adding a prescribed amount of B, Ca and REM to an Al killed steel in a prescribed ratio.
CONSTITUTION: This cold rolled steel plate contains <0.06% C, <0.4% Mn, <0.02% S, 0.0005W0.008% N, 0.005W0.06% acid-sol. Al and B in B/N=0.5W1.5 as basic components and further contains Ca and/or REN in Ca/S=0.5W3 and REM/S=1W2. The plate is annealed continuously. B in said components fixes N exerting unfavorable influence on the drawability and bulgeability, yet since excess B deteriorates the deep drawabiity, the B content is restricted to the fixed range. Ca and REM are effective in enhancing the r-value.
