Steel sheet for hot pressing and process for manufacturing hot pressed member using the steel sheet
A hot-pressing steel sheet has excellent oxidation resistance to be capable of suppressing the formation of scales and ZnO during hot pressing as well as is excellent in cold pressing properties. A process of manufacturing a hot pressed member uses the steel sheet. The hot-pressing steel sheet includes a coating layer containing 10 to 25 mass % of Ni and a balance of Zn and inevitable impurities and having a mass per unit area of 10 to 90 g/m2, and a lubricating layer containing a solid lubricant, in the order named on the surface of a steel sheet.
