Galvanized coating

Name

Zn-Al hot-dip galvanized steel sheet having improved resistance against secular peeling of coating

A Zn-Al hot-dip galvanizedcoating on a steel sheet may exhibit intergranular corrosion and be degraded due to the Al's secular enrichment in the grain boundaries of coating. This is prevented in accordance with the present invention ...
