ABSTRACT:
A method for manufacturing a high-strength clad steel plate excellent in corrosion resistance, which comprises 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.degree. to 1,300.degree. C.; hot-rolling the heated slab at a finishing temperature of at least 800.degree. 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.degree. to 60.degree. C. per second until the temperature of the clad steel plate is less than 450.degree. 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 therebetween, placing a second substrate sheet onto the second cladding sheet, and welding together the peripheries of the first and second substrate sheets through spacers.
