Abstract

Stainless steel for a razor consisting, by weight, of more than 0.55% but not more than 0.73% C, not more than 1.0% Si, not more than 1.0% Mn, not less than 12% but not more than 14% Cr and the balance Fe and incidental impurities, a carbide density in an annealed state being 140 to 600 pieces/100 mu m<2>. The above stainless steel may contain least one of not more than 1.0% Ni and not more than 2% Mo. There is also disclosed a process for producing stainless steel for a razor, comprising the steps of introducing a strip of the above-mentioned steel into a continuous furnace set to a temperature higher than a transformation temperature AC1 of the steel, prior to or during cold rolling, and annealing the steel sheet so that a carbide density of the steel strip is 140 to 600 pieces/100 mu m<2>.
