"ALUMINIZED STAINLESS STEEL AND METHOD FOR PRODUCING SAME" ABSTRACT A method for coating a strip of stainless steel with aluminum, without the need for pre-plating the stainless steel substrate before coating with aluminum. A non-preplated stainless steel substrate is passed through a heating furnace wherein (a) the dew point of the furnace is controlled to substantially reduce the formation of chromium oxides on the surface of the strip and (b) the temperature of the furnace is controlled to substantially reduce the growth of any chromium oxides that may form on the surface of the strip. The aluminum coating is then applied to the substrate by a hot dip procedure. The coated metal product is substantially free of uncoated areas.
