Изобретение относится к черной металлургии, в частности к составам высокоуглеродистой нержавеющей стали для режущих инструментов и может быть использовано для лезвий безопасных бритв. Техническим результатом изобретения является получение более дисперсной структуры стали с равномерным распределением карбидов по толщине ленты, измельчение неметаллических включений и уменьшение их количества. Сущность изобретения заключается в том, что нержавеющая инструментальная сталь содержит, мас.%: углерод 0,55 - 0,70, марганец 0,20 - 1,0, молибден 0,05 - 0,50, алюминий 0,03 - 0,10, титан 0,01 - 0,10 кальций 0,005 - 0,030, хром 12,5 - 15,0, кремний 0,20 - 0,50, ванадий 0,05 - 0,30, бор 0,002 - 0,004, никель 0,08 - 0,30, цирконий 0,05 - 0,10, железо - остальное, при этом суммарное содержание титана и циркония составляет 0,10 - 0,16%, а суммарное содержание марганца и никеля находится в пределах 0,5 - 1,2%.The invention relates to ferrous metallurgy, in particular to compositions of high-carbon stainless steel for cutting tools and can be used for safety razor blades. The technical result of the invention is to obtain a more dispersed steel structure with a uniform distribution of carbides over the thickness of the tape, grinding non-metallic inclusions and reducing their number. The essence of the invention lies in the fact that stainless tool steel contains, wt.%: Carbon 0.55 - 0.70, manganese 0.20 - 1.0, molybdenum 0.05 - 0.50, aluminum 0.03 - 0, 10, titanium 0.01 - 0.10 calcium 0.005 - 0.030, chromium 12.5 - 15.0, silicon 0.20 - 0.50, vanadium 0.05 - 0.30, boron 0.002 - 0.004, nickel 0, 08 - 0.30, zirconium 0.05 - 0.10, iron - the rest, while the total content of titanium and zirconium is 0.10 - 0.16%, and the total content of manganese and nickel is in the range 0.5 - 1 , 2%.
