METHOD OF MANUFACTURING HOT PRESS MEMBER

摘要

It is an object of the present invention to provide a method for manufacturing a hot-pressed member having excellent corrosion resistance, and to provide a method for manufacturing a hot-pressed member having excellent resistance to liquid metal embrittlement, in which liquid metal embrittlement cracking caused by entry of zinc in the coating layer into the steel sheet does not occur. A method for manufacturing a hot-pressed member is characterized by including heating a coated steel sheet to 850°C to 950°C, the coated steel sheet including a substrate steel sheet and a coating layer which is formed on the substrate steel sheet and which contains 10% to 25% by mass of Ni and the balance being Zn and incidental impurities, in which the coating weight of the coating layer is 10 to 90 g/m 2 per a side; and starting hot press forming when the temperature of the coated steel sheet which has been heated is 650°C to 800°C.
