Abstract

PURPOSE: To produce a high strength cold-rolled steel plate of superior weldability, coatability and workability, by making the addition amount of strength imparting elements as small as possible and applying the specific heat treatment at the continuous annealing, at the time of producing a steel plate for automobiles.
CONSTITUTION: A steel slab contg. 0.05W0.12% C, ≤1.2% Si, 0.7W1.5% Mn, 0.04W0.15% P, and 0.01W0.10% sol. Al is hot-rolled, and cold-rolled to produce a steel plate. In continuous annealing of the steel plate, first it is soaked for 20secW 2min at 730W850°C, after which it is quickly cooled by gas-water cooling at 30W 300°C/sec cooling rates. Or it is quickly cooled down to 500W300°C temperature range by said method, after which it is subjected to over aging treatment at 300W 500°C. The amounts of C, Mn, Si, P, Cr which are strength imparting elements are decreased as far as possible to prevent the degradation in weldability and coatability. The strength may be improved by the heat treatment under specific conditions.
