Iron-Zine Alloy Electroplated Steel for Automotive Body Panels 820424

Iron-zinc alloy electroplated steel for automotive body panels has been developed. This newly developed steel is produced in a conventional electrogalvanizing line using electrolyte composed mainly of iron salt and zinc salt. Corrosion resistance after electropainting of this product is quite excellent, the same as that of galvannealed steel and much better than that of electrogalvanized steel and cold rolled steel. Weldability of this product is also the same as that of galvannealed steel. Adhesion of the deposit is better than that of galvannealed steel and no “pimple” problems occur during stamping. Thus, this product possesses advantages of both galvannealed steel and electrogalvanized steel.
