A method for manufacturing titanium clad steel plate by forming a slab assembly having an alloy steel substrate, a titanium metal or alloy cladding on said substrate and a Ni-Cr alloy foil or film having opposed surfaces between said alloy steel and said cladding. The Ni-Cr alloy foil or film has one surface in surface contact with the cladding and the opposed surface in surface contact with the alloy steel substrate. The Ni-Cr alloy contains 32.5 to 40 wt. % Cr and 55 to 65 wt. % Ni. The slab assembly is heated at a temperature of 850.degree. to 1010.degree. C. The heated slab assembly is hot rolled with a reduction ratio of 30% or more to form the titanium clad steel plate.
