The cladding plate of 22MnB5 high-strength steel and 201 stainless steel was prepared by the warm rolling process, and the interfacial microstructures and mechanical properties of the cladding plate were studied by scanning electron microscope (SEM), X-ray diffraction and tensile test. The results show that the cladding plate prepared by the warm rolling process has three microstructures, namely, the decarburized layer, the bonding interface and the carburized layer from the base layer to the cladding layer. The thickness of the decarburized layer increases with the increasing of reduction ratio, the deformation induced martensite transformation is found in the austenite structure of the cladding layer, and the microstructure of the base layer after heat treatment is lath martensite. In addition, there is mutual diffusion of elements at the interface of the cladding plate, and because of the strong diffusion ability of C, Cr and Mn elements, the thickness of the diffusion layer increases after heat treatment. Furthermore, the tensile strength of the cladding plate increases and the elongation decreases with the increasing of reduction ratio, and after heat treatment, the tensile strength of the cladding plate reaches more than 1160 MPa and the elongation is also improved.
