Document Type and Number:
WIPO Patent Application WO/2020/049833
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a steel sheet for hot pressing that has excellent corrosion resistance and reduces the amount of Zn metal that is lost to oxidation during the heating process of hot pressing. A steel sheet for hot pressing that has: a Zn alloy plating layer that is at the surface of the steel sheet, there being no more than 120 g/m2 of plating per side; and an oxide layer that is at the surface of the Zn alloy plating layer, the oxide having a lower standard reaction Gibbs energy at 900°C than ZnO.
