Highlights: • The rolling temperature affects the grain size and microstructural phases of the composite plates. • The rolling temperature affects tensile strength and bending strength of 2Cr13/316L properties of the composite plates. • The temperature gradient and thermal deformation of center and outside regions are different during rolling process. • Composite plate with higher strength and elongation can be obtained by rolling processes. - Abstract: The microstructure and mechanical properties of 2Cr13/316L composite plates by hot-rolling at different rolling temperatures of 1130 °C, 1180 °C, 1250 °C, 1300 °C are investigated in details. With the increase of the rolling temperature, the tensile strength and bending strength of 2Cr13/316Lwere reduced first and then increased slightly due to the coarsening of grains and the increasing of ferrite content in 2Cr13 layers. The highest tensile elongation is obtained at the composite plate with rolling temperature of 1180 °C. 2Cr13/316L composite plates obtained by hot rolling processes were able to withstand larger bending deformation, and no cracks or interfacial delamination can be found in the bending process because of a strong combined interface.
