The invention relates to a nichrome and carbon steel composite board as well as a production method thereof, which belong to the technical field of metal composite board production. According to the invention, the composite board is characterized in that the smelted X60MS and Incoloy 825 nichrome casting blanks enable respective cogging and rolling, the size of a designed intermediate blank can be rolled; then the polish-grinding treatment can be carried out on surface of billets, the billet are symmetrically composited, an upper layer and a lower layer are X60MS material carbon steels, the two intermediate layers are nichrome, nickel foils with different thickness can be selectively added between the carbon steel and nichrome or a soldering flux is not added, and a solder resist is added between the nichrome and the nichrome. then four edges welding for edge sealing can be carried out on the billets, and a mechanical pump is used for vacuum-pumping treatment. The composite board has the advantages that the shearing intensity of a compound interface is more than 500MPa, flaw detection can reach the requirement of grade one in standard binding rate in GB/T 8165< composite board and steel band>, which is 100% binding. When the tensile strength of nichrome reaches 760MPa, elongation percentage A50.8 can reach 30%, and tensile strength of X60MS can reach 600MPa, impact energy at -20 DEG C can reach 300-400J, and shearing area of DWTT at -10 DEG C is greater than 85%.
