Abstract
PURPOSE: To obtain a cold rolled steel plate with enhanced secondary workability for deep drawing by adding a very small amount of B to an extra-low C cold rolled steel plate contg. Ti so as to increase the strength of the grain boundaries.
CONSTITUTION: This cold rolled steel plate consists of 0.002W0.020% C, ≤0.1% Si, ≤0.50% Mn, 0.002W0.150% acid sol. Al, ≤0.008% N, 0.02W0.50% Ti (Ti/C>4), ≤0.008% B, ≤0.02% P and the balance Fe with inevitable impurities. In this composition B is the most important element for improving the secondary workability. It is quickly diffused in steel, easily segregated at the grain boundaries, and increases the strength of the grain boundaries like C. This cold rolled steel plate is soft and has superior mechanical properties and deep drawability.
