The press formability and corrosion resistance of electrogalvanized steel with Mg containing phosphate film were investigated. (1) The phosphate film could reduce the friction coefficient of electrogalvanized steel sheet and good press formability was obtained. It was seemed that the morphology of the phosphate film could be effective on friction property. (2) The phosphate film could improve the perforation corrosionresistance of electrogalvanized steel sheet. It was suggested that the film could delay the start of Zn corrosion and also could stabilize the corrosion products of Zn.
