PURPOSE:To obtain a steel sheet fit to undergo single enameling and double enameling and having superior workability and suitability to enameling by continuous casting by specifying the amounts of C, Mn, N and O contained in steel. CONSTITUTION:This steel sheet obtd. by continuous casting consists of <=0.0050% C, <=0.6% Mn, <=0.0050% N, 0.016-<0.030% O and the balance Fe or further contains <=0.05% Cu and 0.0001-0.0050% B and/or 0.003-0.080% Nb. The steel sheet is fit to undergo single enameling and double enameling, and the calcining temp. range is extended because of the high A1 transformation point. The steel sheet gives enamel having high adhesive strength and free from fish scale and bubbles.
