| titleOfInvention | Surface-treated steel sheet |
| abstract | An inexpensive surface-treated steel sheet that does not use chromium and does not change color when heated at 500 ° C. or higher and has excellent corrosion resistance after heating. SOLUTION: A hot dip galvanized layer having a plating adhesion amount of 80 g / m 2 or more on one surface of a steel plate is provided on the surface of the steel plate, and 50% by mass or more of an inorganic substance not containing Cr is contained on the galvanized layer. Fe having an inorganic coating and an amount of Al [Al] of 0.20 to 0.40 g / m 2 and a Zn content of [Al] × 0.2 g / m 2 or less at the interface between the steel sheet and the hot-dip galvanized layer. -Al alloy layer is present, and the arithmetic average roughness Ra1 of the steel sheet measured by peeling off the inorganic coating, hot-dip galvanized layer and Fe-Al alloy layer is 0.4 to 1.2 μm, and the inorganic A surface-treated steel sheet characterized in that the arithmetic average roughness Ra2 of the steel sheet measured after film formation is 0.3 to 1.2 μm, and the Ra1 and Ra2 satisfy the following formula (1): Ra2 <1.8-0.9 × Ra1 (1).
