Abstract
PURPOSE: To produce a titled steel plate providde with both delayed aging at room temp. and wiring performance for baking by hot rolling the specific composition steel contg. c, Si, Mn, P, sol.Al then cold rolling the same and subjecting the same to recrystallization annealing followed by galvanizing and alloying treatment.
CONSTITUTION: The steel of the composition contg. 0.002W0.12% C, ≤0.6% Si, 0.6W1.6% Mn, ≤0.14% P, and ≤0.3% sol.Al wt%, satisfying ≤0.20% (C%+P%), and if necessary, contg. ≥1 kinds of 0.04W0.80% Cr, 0.0005W0.0030% B, and 0.02W 0.40% V, and consisting of the balance Fe and unavoidable impurities is subjected to the following treatment: After it is hot-rolled under the conditions of 780W950°C finish temps., and 670W750°C coiling temps., it is cold-rolled under the conditions of ≥40% draft. Thence, it is subjected to recrystallization annealing at between 650W 900°C in a con tinuous hot-dipped galvabizing line, and is immersed in a zinc plating bath of 420W 520°C in the cooling process after the annealin, it is then held for ≥3sec at 520W 640°C, whereby it is subjected to alloying treatment. The resultant plated steel plate has good spot weldability as well.
