The invention provides a Martensite stainless-steel composite steel plate and a production method thereof, belonging to the technical field of production of stainless steel composite plates. The method is realized through the following process routes: steel billet combination, heating, rolling control and heat treatment, wherein pack rolling of double billets is adopted, i.e., the upper and lower layers adopt A516Gr70 carbon steel, and two middle layers adopt 410S Martensite stainless steel; an isolation agent is added between two layers of the Martensite stainless steel; four edges of the combined billet is welded and sealed; and a vacuum pump is utilized for vacuum pumping. The invention has the following advantages: the Martensite stainless-steel composite steel plate has excellent strength-toughness and mechanical property, improves comprehensive utilization rate of materials, and further reduces cost at the same time.
