The invention discloses DDQ-grade hot-rolled pickling cold-formed steel and a manufacturing method thereof, and belongs to the technical field of hot-rolled pickling cold-formed steel. The steel comprises the following chemical components including, by weight percent, smaller than or equal to 0.0020% of C, smaller than or equal to 0.03% of Si, 0.08%-0.25% of Mn, 0.005%-0.015% of P, 0.05%-0.015% ofS, 0.025%-0.045% of Als, smaller than or equal to 0.0040% of N, 0.030%-0.050% of Ti, 0.015%-0.030% of Nb, and the balance Fe and inevitable impurities. According to the steel, multiple elements are added on the basis of traditional hot-rolled cold-formed steel, the content of each element is reasonably adjusted, so that the yield strength and the tensile strength of the steel are improved to a certain extent, the ductility of the steel is well improved, meanwhile, the thickness of a steel plate meets the use requirement, and a cold-rolled steel plate is effectively replaced. According to themanufacturing method of the steel, the components, the component content and the specific production process of the steel plate are optimally designed, the yield strength and the elongation of the obtained steel plate are guaranteed, and meanwhile, the surface characteristics of the steel plate are improved through secondary pickling, so that the steel plate has high-grade roughness and surface gloss comparable with surface gloss of a cold-rolled plate.
