Abstract (en)
Disclosed is a high-strength hot-rolled plated steel sheet capable of suppressing material deterioration at the time of plating, while having high strength, and a method for manufacturing the same. The high-strength hot-rolled plated steel sheet may include: a hot-rolled steel sheet base material composed of 0.03-0.1wt% of C, below 0.06wt% of Si, 0.7-2.0wt% of Mn, below 0.02wt% of P, below 0.01wt% of S, 0.1-0.5wt% of one or more precipitate forming elements, 0.3-1.0wt% of Al, 0.1-0.5wt% of Mo, Fe, and unavoidable impurities; and a plated layer formed on the surface of the hot-rolled steel sheet base material.
