PURPOSE:To obtain the titled steel plate having high strength after baking and excellent in fishscale resistance, by incorporating specific amounts of C, Mn, N, and Ti to a hot-rolled steel for vitreous enameling and by allowing specific relations to hold among Ti, C, N, and S included in inevitable impurities. CONSTITUTION:The steel has a composition consisting of, by weight, 0.005-0.05% C, 1.5-3% Mn, 0.003-0.015% N, 0.05-0.2% Ti, and the balance Fe with inevitable impurity elements. Further, relations in a inequality hold among Ti, C, N, and an inevitable impurity element. This steel is hot-rolled, wound up at 500-700 deg.C, and allowed to form a hardened structure at the time of cooling, so that hot-rolled steel plate for vitreous enameling can be obtained.
