An object of the present invention is to provide a cladding material, for stainless steel clad steel plate, with good sea water corrosion resistance that offers bonding interface integrity with improved reliability while simultaneously maintaining good properties (corrosion resistance and mechanical properties) of the base material and the cladding material, and also to provide a stainless steel clad steel plate including such a cladding material and a method for manufacturing such a stainless steel clad steel plate. Provided are a cladding material for stainless steel clad steel plate and a stainless steel clad steel plate including such a cladding material. The cladding material for stainless steel clad steel plate comprising, by mass%, 0.03% or less carbon, 1.5% or less silicon, 2.0% or less manganese, 0.04% or less phosphorus, 0.03% or less sulfur, 22.0% to 25.0% nickel, 21.0% to 25.0% chromium, 2.0% to 5.0% molybdenum, 0.15% to 0.25% nitrogen, and the balance being iron and incidental, wherein the critical pitting temperature (CPT) after normalization as determined in accordance with ASTM is 45°C or higher, and the corrosion loss at a welded zone as determined by a corrosion test in accordance with NORSOK Standard is 1.0 g/m 2 or less. |
