摘要: An enameling cold rolled steel sheet with a high enamel adhesive property which requires no pickling step before enameling, characterized by an Mn content kept within 0.05 to 0.20%, and the relation between the surface roughness and the Mn content of said steel sheet satisfying at least one of the following two equations:(a) Number of peaks of 1.3.mu. and over/inch .gtoreq. 1,200.sup.. (Mn% - 0.1)(b) R.sub.z (.mu.) .gtoreq. 60.sup.. (Mn% - 0.1)

摘要: An enameling steel sheet characterized by a manganese content of 0.50 wt.% or under and the elimination of annealing after the final cold rolling. A satisfactory enamel adhesive property can be obtained by enameling and baking said enameling steel sheet in as-cold-rolled state after only degreasing and drying.
