STEEL SHEET FOR HOT PRESSING AND METHOD OF MANUFACTURING HOT-PRESSED PART USING STEEL SHEET FOR HOT PRESSING
摘要:
In order to provide a steel sheet for hot pressing from which a hot-pressed part excellent in perforation corrosion resistance is obtainable and a method of manufacturing a hot-pressed part using the steel sheet for hot pressing, provided is a steel sheet for hot pressing having, sequentially on a surface of a base steel sheet: a plating layer I containing 60% by mass or more of Ni and the remainder consisting of Zn and inevitable impurities, a coating mass thereof being 0.01 to 5 g/m2; and a plating layer II containing 10 to 25% by mass of Ni and the remainder consisting of Zn and inevitable impurities, a coating mass thereof being 10 to 90 g/m2.
