METHOD FOR MANUFACTURING HIGH-STRENGTH CLAD STEEL PLATE EXCELLENT IN CORROSION RESISTANCE ABSTRACT OF THE DISCLOSURE A method for manufacturing a high-strength clad steel plate excellent in corrosion resistance, which com- prises the steps of: placing a cladding sheet comprising stainless steel onto at least one of the surfaces of a substrate sheet comprising any one of carbon steel and low-alloy steel; welding together the peripheries of the substrate sheet and the cladding sheet to prepare a slab; heating the prepared slab to a temperature of from 1,050 to 1,300°C; hot-rolling the heated slab at a finishing temperature of at least 800°C to obtain a clad steel plate comprising the substrate sheet and the cladding sheet; and cooling the obtained clad steel plate at a cooling rate of from 2 to 60°C per second until the temperature of the clad steel plate becomes under 450°C. The above-mentioned slab may be a composite slab prepared by: placing a first cladding sheet onto a first substrate sheet, applying a peeloff material onto the upper surface of the first cladding sheet, placing a second cladding sheet onto the first cladding sheet through the peeloff material there- between, placing a second substrate sheet onto the second - 1 - cladding sheet, and welding together the peripheries of the first and second substrate sheets through spacers. - 2 -
