The invention provides a rolling method of a multilayer stainless steel metal composite plate. Thicker martensitic-grade stainless steel is selected as an intermediate layer, thinner austenitic-grade stainless steel and the martensitic-grade stainless steel are sequentially stacked on two sides, and the multilayer stainless steel metal composite plate is formed through hot rolling and composition of the stainless steel. A manufacturing process comprises steps as follows: plate materials are subjected to surface treatment before rolling and then are stacked sequentially, the periphery of the multilayer stacked metal is welded through argon arc welding, the plate materials cannot be oxidized during heating, and the welded plate materials are subjected to multi-pass rolling through control of the rolling temperature and the rolling reduction. The rolled composite plate is subjected to air cooling and structure and performance analysis, and a reasonable heat treatment technology is selected according to an analysis result, that is, the performance of the metal composite plate is further improved through the heat treatment process including steps of full annealing, quenching and tempering.
