The invention belongs to the technical field of stainless steel material application, and particularly discloses economical duplex stainless steel, which is prepared from the following components in percentage by weight: 0.02 to 0.06 percent of C, 0.5 to 1.2 percent of Si, 3.0 to 5.5 percent of Mn, 2.3 to 4.2 percent of Ni, 19.5 to 21.5 percent of Cr, 0.2 to 2.0 percent of Cu, 0.15 to 0.25 percent of N, 0.1 to 0.2 percent of W, 0.025 to 0.035 percent of P, 0.008 to 0.015 percent of S, 0.5 to 1.2 percent of Mo, 0.005 to 0.02 percent of B, 0.01 to 0.15 percent of rare earth Ce and the balance of Fe and inevitable impurities. The preparation method comprises the following steps: step 1, smelting to obtain a raw material solution; 2, the raw material liquid is guided into an open-type raw material liquid storage box; and step 3, carrying out ultrasonication on the raw material solution. And 4, stainless steel blank casting. The method has the beneficial effects that the duplex stainless steel ...
