摘要:
A hot press formed product being improved in corrosion resistance and in the adhesion of a coating film, which is produced by subjecting a zinc-based metal plated steel product to a hot press forming, and has a zinc-based metal plating layer containing and, formed thereon, a zinc oxide layer, wherein the uppermost zinc oxide layer has an average thickness of 2 mum or less; and a hot press formed product being excellent in corrosion resistance, the adhesion of a coating film, the resistance to corrosion after coating, and weldability, which has a basis steel plate (1) and, formed thereon, a layer (2) consisting essentially of an iron-zinc solid solution phase and, as the uppermost layer, a zinc oxide layer (3) having an average thickness of 5 mum or less, and has substantially no iron-zinc intermetallic compound phase, wherein the iron-zinc solid solution layer (2) and the zinc oxide layer (3) contain Al in a total amount of 0.5 g/m or less and/or contain Al oxides in a total amount of 5 mg/m or less in terms of Al.
