A cold-rolled steel sheet suitable for enamel coating, which essentially consists of, on a weight basis,… C up to 0.005%,… P up to 0.02%,… S up to 0.03%,… N 0.005% to 0.012%,… Ti up to 0.15% and Ti >/= (<4><8>/12C + <4><8>/32S)%,… Cu up to 0.08%, and… at least one member selected from As, Sb, and Bi in a total amount of 0.003% to 0.03%, or Se and/or Te in a total amount of 0.003% to 0.05%, or their combination in a total amount of 0.002 to 0.05%, the balance being Fe and concomitant impurities. …<??>The steel is made by continuously casting a molten steel having the above-mentioned composition, hot rolling and then cold rolling the steel, and either continuously annealing or box-annealing the steel at a temperature in the range from the recrystallization temperature to the Ac3 point. |
