Abstract
PURPOSE: To manufacture a high tensile hot rolled steel sheet suitable for deep drawing by adding Nb, Ti and V besides C, Mn, Si, N and sol. Al as basic components and selecting hot rolling conditions or further adding Cu, Ni and Cr.
CONSTITUTION: Steel contg. C; 0.03W0.20%, Mn; 0.30W2.0%, Si; 0.05W1.0%, N; 0.0005W0.01%, sol. Al; 0.005W0.10% and one or more out of Nb; 0.01W0.10%, Ti; 0.01W0.20% and V; 0.01W0.30% or further contg. one or more out of Cu; 0.2W0.5%, Ni; 0.05W0.3% and Cr; 0.1W1.5% is bloomed or continuous-cast into an ingot, heated to 1,320W1,360°C, finish rolled at 900W1,000°C, and coiled at 500W680°C to obtain a high tensile steel sheet with low intrafacial plastic anisotropy suitable for deep drawing.
