Provided is an intermediate material for a stainless steel for knives, which can be highly hardened by a short-time heat treatment in a hardening heat treatment process and has an excellent carbide distribution. An intermediate material for a stainless steel for knives, which is substantially composed of a FCC phase, and which has been hot-rolled but is not annealed yet. The intermediate material has a chemical composition comprising, in mass%, 0.46 to 0.72% of C, 0.15 to 0.55% of Si, 0.45 to 1.00% of Mn, 12.5 to 13.9% of Cr, 0 to 2.0% of Mo+W/2, and a remainder made up by Fe and impurities, and has a KAM value of 0.5˚ or more at a position which is located at a depth of 1/4 of the thickness from the surface of the surface to be rolled. |
