Изобретение относитс  к области изыскани  материалов, предназначенных дл  гор чего деформировани  металлов и сплавов.The invention relates to the field of research of materials intended for the hot deformation of metals and alloys.

Известна штампова  сталь, содержаща  хром, молибден, ванадий.Known stamped steel containing chromium, molybdenum, vanadium.

Предложенна  сталь отличаетс  от известной пониженным содержанием хрома и ванади  и дополнительным легированием ниобием. Это позвол ет повысить устойчивость против отпуска.The proposed steel differs from the known low content of chromium and vanadium and the additional doping with niobium. This allows for increased resistance to tempering.

Сталь имеет следующий состав (в %):Steel has the following composition (%):

Углерод0,32-0,44 Хром3,7-4,4Carbon0.32-0.44 Chromium 3.7-4.4

Молибден0,9-2,0Molybdenum0,9-2,0

Ванадий0,6-0,9Vanadium 0.6-0.9

Ниобий0,05-0,25Niobium 0.05-0.25

ЖелезоостальноеIron rest

Предел прочности и предел текучести стали составл ет соответственно 204-210 и 185- 190 кг/мм. Твердость стали после 200-часового отпуска при 550°С равна 48 HRC.The tensile strength and yield strength of steel are respectively 204-210 and 185-190 kg / mm. The hardness of steel after 200-hour tempering at 550 ° С is 48 HRC.

Предмет изобретени Subject invention

Штампова  сталь содержаща  углерод, хром, молибден, ванадий, железо, отличающа с  тем, что, с целью повышени  устойчивости против отпуска, она дополнительно содержит пнобий при следующем соотношении компонентов (в %):Stamped steel containing carbon, chromium, molybdenum, vanadium, iron, characterized in that, in order to increase the resistance against tempering, it additionally contains petite in the following ratio of components (in%):

Углерод0,32-0,44Carbon0.32-0.44

Хром3,7-4,4Chrome 3.7-4.4
