| description | A galvanized steel sheet for hot forming, the galvanized steel sheet including a galvanized film provided on a surface of a steel sheet,
wherein the steel sheet has a chemical composition consisting of, in mass%,
C: 0.02% to 0.58%,
Mn: 0.5% to 3.0%,
sol. Al: 0.005% to 1.0%,
a predetermined element(s) as necessary;
Si: less than or equal to 2.0%,
P: less than or equal to 0.03%,
S: less than or equal to 0.004%,
N: less than or equal to 0.01%, and
the balance: Fe and impurities,
wherein a content of Mn in a portion from an interface of the steel sheet and the galvanized film to a depth of 5 µm is more than or equal to 0.3 mass %,
wherein the galvanized film has a plating coverage of 40 g/m 2 to 110g/m 2 , an Al content of more than or equal to 150 mg/m 2 within the galvanized film, and an Al concentration of less than or equal to 0.5 mass %, and
wherein the galvanized steel sheet is used for an application in which the galvanized steel sheet is heated to 700°C or above and is then subjected to hot forming. |
