ABSTRACT:
Disclosed is a phosphated steel product and a method for producing the product. The method comprises passing at least one side of a steel strip through a molten bath of a metal selected from the group consisting of Zn-Al and Zn-Fe to form a first coating, electroplating a second coating consisting of essentially a pure metal selected from the group consisting of Mn, Fe and Ni onto the first coating and subjecting the exposed surface of the second coating to a phosphating treatment to form a phosphate coating on the second coating.
