Abstract:
A cold rolled steel sheet suitable for enamel coating is provided which consists essentially 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% andTi.gtoreq.(48/12C+48/14N+48/32S)%,Cu: up to 0.08%, andat 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 produced by continuously casting a molten steel having the same composition as above, hot rolling and then cold rolling the steel, and continuously annealing the steel at a temperature in the range from the recrystallization temperature to the Ac.sub.3 point. It is also produced by substantially the same procedure but by box annealing the steel having a titanium content increased at a temperature in the range from the recrystallization temperature to 800.degree. C.
