HOT-STAMPED MOLDED BODY, AND METHOD FOR PRODUCING HOT STAMP MOLDED BODY |
摘要 |
Provided are: a hot-stamped product which can be obtained by hot-stamping an electro-galvanized steel sheet having a low coating weight through use of a rapid heating means such as electrical heating, induction heating or the like at a high efficiency without causing the adhesion of the plating to a die and which can ensure high coating adhesion even without conducting post-treatment such as shot-blasting after the hot stamping; and a process for producing the same. A hot-stamped product obtained by hot-stamping an electro-galvanized steel sheet which has a prescribed composition and which has been plated with electrolytic zinc at a coating weight of 5 to less than 40g/m2 per side, wherein: the plating layer of the hot-stamped product contains 0 to 15g/m2 of a Zn-Fe intermetallic compound with the balance consisting of an Fe-Zn solid-solution phase; and 1×10 to 1×104 particles having a mean diameter of 10nm to 1µm are present in the plating layer of the hot-stamped product per millimeter of the length of the plating layer. |
