Abstract

PURPOSE: To provide a hot-rolled high-strength steel sheet which comprises C, Si, Mn, Ti, S and Al at a prescribed ratio and the rest of Fe and both sides of which can be enameled without causing a chipping defect.
CONSTITUTION: A hot-rolled high-strength steel sheet for both-side enameling comprises 0.05W0.15% of C, 1.0% or less of Si, 0.3W1.5% of Mn, 0.1W0.5% of Ti, 0.02W0.05% of S, 0.1% or less of Al and the rest of Fe and unavoidable impurities. The C is added to assure a necessary strength. The Si is added for deoxidation and strengthening. The Mn is added to assure a prescribed strength. The Ti is added to improve the finished external appearance of enameling and reduce baking strain and is important as a combined element with the S to heighten the resistance against chipping. The Al is added for deoxidation. The tensile strength of the hot-rolled steel sheet is 50kg/mm2 or more.
