This application belongs to the field of metal composite plate preparation, specifically relating to a 304 stainless steel-high manganese steel composite plate and its preparation method. The preparation method includes the following steps: S1, obtaining 304 stainless steel slabs and high manganese steel slabs, stacking and welding the 304 stainless steel slabs and high manganese steel slabs to obtain a first composite slab; S2, heating the first composite slab to obtain a second composite slab; S3, rolling the second composite slab to obtain the 304 stainless steel-high manganese steel composite plate. This application solves the problem of "excessive thinning of the soft phase" caused by the hardness difference in "soft / hard" composite plates during rolling by introducing a thickness ratio compensation formula in the billet assembly stage. This significantly improves the thickness ratio accuracy of the final product. By dynamically adjusting the speed ratio, the rolling effect generated by "variable speed rolling" effectively offsets the internal bending moment caused by uncoordinated deformation, significantly reducing the warping and buckling phenomenon of the composite plate.
