Document Type and Number:
WIPO Patent Application WO/2012/133671
Kind Code:
A1
Abstract:
The surface-treated steel sheet comprises a steel sheet and a plating layer comprising zinc and vanadium that is formed on one or both surfaces of the steel sheet, wherein the plating layer has a vanadium content between 1 and 20%; a basis weight between 3 g/m2 and 40 g/m2; multiple dendritic arms that have grown in the direction of thickness of the steel sheet; and an x/y ratio, where x is the vanadium content outside the arms and y is the vanadium content inside the arms, between 1.1 and 3.0 in terms of elemental vanadium.
