【Example】
Molten Zn- containing Al: 6% by mass, Mg: 3% by mass, Ti: 0.02% by mass, B: 0.008% by mass, Si: 0.01% by mass at a plating adhesion amount of 120 g / m 2 per one side A hot-dip galvanized steel sheet having a thickness of 0.5 mm on which an Al-Mg alloy plating layer was formed was manufactured on a continuous hot dip galvanizing line of a Zenzimir method.
The hot-dip galvanized steel sheet was subjected to surface conditioning treatment, washed by hot water washing and water washing, and dried. Next, a coating type chromate treatment solution (Surfcoat NRC300NS: manufactured by Nippon Paint Co., Ltd.) was applied by a roll coater and dried at 100 ° C. to form a chromate film having a total Cr adhesion amount of 40 mg / m 2 .
