摘要： PROBLEM TO BE SOLVED: To provide a coated and heat-treated steel material which has appropriate corrosion resistance after having been painted as an automotive member and can suppress the production of scale due to heat treatment, even when having been subjected to the heat treatment of heating at least a part of a steel material having a plated film on at least one side to a quenchable temperature range and subsequently cooling it.
SOLUTION: The coated and heat-treated steel material is formed by conducting the heat treatment of heating at least a part of the steel material that has the aluminum-based plated film coated on at least one side and has been subjected to an alloying treatment at the Ac
3 point or lower, to the quenchable temperature range; and has a film in which iron and aluminum are alloyed, on the surface of at least one part of a portion that has been heat treated. The film has corrosion resistance and also can secure a lubricating function at a high temperature.

This steel sheet has a chemical composition consisting of, by mass, 0.15 to 0.45% C, 0.5 to 3.0% Mn+Cr, further one or more among ≤0.05% P, ≤0.03% S, ≤0.5% Si, ≤2% Ni, ≤1% Cu, ≤1% V and ≤1% Al and the balance Fe with impurities; and this Zn-based plating layer has 10 to 110 g/m
2 Zn coating weight. The steel sheet is heated and hot pressed under the following conditions: heating is applied at a heating temperature not lower than the Ac
3 point and at a dew point of heating atmosphere ranging from 30 to 80°C; cooling rate at hot pressing is not lower than the upper critical cooling rate of the steel sheet. The resulting hot pressed steel sheet member has an amount of diffusible hydrogen directly after the hot pressing not larger than 0.20 ppm and a tensile strength not lower than 1.2 GPa.
