A 15-layer composite plate was developed. The microstructure and mechanical properties were characterized by scanning electron microscopy, Vickers microhardness, tensile, and bending tests. Particularly, the effects of hot-rolling at different rolling temperatures of 1130, 1180, 1250, and 1300 °C on the microstructure and mechanical properties of the 2Cr13/316L/9Cr18MoV composite plates were investigated in detail. The results indicated that, with the increase in the rolling temperature, the tensile strength was first decreased and then slightly increased by the coarsening of grains and the increase in the ferrite content in the 2Cr13 layers. The highest tensile elongation of 12.5% and tensile strength of 958.1 MPa were obtained for the composite plate manufactured with the rolling temperature of 1180 °C. The 2Cr13/316L/9Cr18MoV composite plates with rolling temperatures of 1130 and 1180 °C obtained by hot-rolling processes withstood larger bending deformations, showing only local cracks after the bending process because of their strong combined interfaces. However, during the bending to 130° of specimens fabricated with the rolling temperature of 1250 and 1300 °C, the specimens experienced direct fracture at very low bending displacements.
