ABSTRACT:
Composite-coated flat-rolled steel can stock processing and product for fabrication of sheet metal cans, in particular for three-piece, welded or cemented side seam cans. Single or double-reduced, low carbon, flat-rolled steel of a gage in the range of about 55 to 110 pounds per base box is flash coated with tin (0.05 #/bb), which is alloyed with the steel base metal; at least 0.20 #/bb of tin is added to one surface only, flow brightened and water quenched; chemical treatment chrome oxide coating of about 100 to 750 milligrams per square foot is added to both surfaces and an organic coating of 2.5 to 15 milligrams per square inch is added to the surface which is free of flow-brightened tin for disposition internally of a can fabricated from such coated can stock. The equivalent of quarter-pound and higher coating weight tinplate protection is provided while decreasing tin requirements and maintaining three-piece can fabrication properties not available with coating metal substitutes for tin.
