Abstract (en)
[origin: EP2889393A1] There is provided an intermediate material for stainless steel for edged tools having an excellent carbide distribution, enabling hardness to be increased by heat treatment for a short time during hardening. The intermediate material for stainless steel for edged tools substantially includes an FCC phase, and has a composition of, in % by 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 of Fe and impurities. Furthermore, a KAM value in a position at 1/4 in depth of a plane thickness from a surface of a rolled plane is 0.5° or more.
