ELECTROGALVANIZED SHEET STEEL

摘要

PROBLEM TO BE SOLVED: To provide an electrogalvanized steel sheet superior in surface appearance, without generation of appearance unevenness caused by surface defects on a base sheet. SOLUTION: The electrogalvanized steel sheet is obtained by forming a Ni-Fe alloy layer including 5-60% of Fe and substantially the balance Ni and the first layer, and forming the electrolytic zinc plating layer thereon as the second layer. The coating weight of Ni-Fe alloy layer is preferably 10-500 mg/m2.
