Document Type and Number:
WIPO Patent Application WO/2023/153099
Kind Code:
A1
Abstract:
The present invention provides a steel sheet for hot pressing, the steel sheet being prevented from the generation of scales due to a coating layer and being reduced in adhesion of a metal to heating facilities, thereby preventing liquid metal embrittlement cracking during hot pressing and achieving excellent corrosion resistance after coating. The present invention provides a steel sheet for hot pressing, the steel sheet comprising a base steel sheet and coating layers which are provided on both surfaces of the base steel sheet and have a thickness of 7 to 20 µm, wherein: the coating layers are formed of Ni or an Ni-based alloy; and the Zn content in the coating layers is 0 to 10% by mass.
