Description
Изобретение относится к области металлургии, а именно к составам конструкционных сталей, которые могут быть использованы в общем машиностроении.The invention relates to the field of metallurgy, and in particular to compositions of structural steels that can be used in general engineering.
Известна сталь, содержащая, мас.%: углерод 0,05-01,3; кремний ≤ 3,0; марганец 0,01-3,0; ванадий 0,005-1,0; хром 0,005-5,0; молибден 0,005-5,0; ниобий 0,002-1,0; цирконий 0,002-1,0; титан 0,002-1,0; алюминий 0,01-3,0; железо - остальное [1].Known steel containing, wt.%: Carbon 0.05-01.3; silicon ≤ 3.0; manganese 0.01-3.0; vanadium 0.005-1.0; chrome 0.005-5.0; molybdenum 0.005-5.0; niobium 0.002-1.0; zirconium 0.002-1.0; titanium 0.002-1.0; aluminum 0.01-3.0; iron - the rest [1].
Задачей изобретения является повышение ударной вязкости стали.The objective of the invention is to increase the toughness of steel.
Технический результат достигается тем, что в составе стали, содержащей углерод, кремний, марганец, ванадий, хром, молибден, ниобий, цирконий, титан, алюминий, железо, компоненты находятся при следующем соотношении, мас.%: углерод 0,15-0,3; кремний 0,05-0,15; марганец 0,05-0,15; ванадий 1,0-1,5; хром 0,5-1,0; молибден 0,5-1,0; ниобий 0,1-0,3; цирконий 3,15-4,3; титан 0,1-0,2; алюминий 0,15-0,3; железо - остальное.The technical result is achieved by the fact that in the composition of the steel containing carbon, silicon, manganese, vanadium, chromium, molybdenum, niobium, zirconium, titanium, aluminum, iron, the components are in the following ratio, wt.%: Carbon 0.15-0, 3; silicon 0.05-0.15; manganese 0.05-0.15; vanadium 1.0-1.5; chrome 0.5-1.0; molybdenum 0.5-1.0; niobium 0.1-0.3; zirconium 3.15-4.3; titanium 0.1-0.2; aluminum 0.15-0.3; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Повышение ударной вязкости стали достигается за счет комплексного влияния компонентов, входящих в ее состав. Хром стабилизирует карбиды. Молибден, ниобий, цирконий и ванадий упрочняют твердый раствор. Алюминий выполняет функцию раскислителя. Титан способствует образованию мелкозернистой структуры стали.An increase in the toughness of steel is achieved due to the complex effect of the components included in its composition. Chrome stabilizes carbides. Molybdenum, niobium, zirconium and vanadium strengthen the solid solution. Aluminum acts as a deoxidizer. Titanium contributes to the formation of a fine-grained steel structure.
Сталь может быть выполнена кислым конвертным способом. Основной исходный материал для выплавки стали - бессемеровский чугун и стальной лом. Сталь подлежит термической обработке по режиму: нормализация при температуре 950°С; закалка при температуре 840-860°С в масле; отпуск при температуре 160-200°С.Steel can be made acidic envelope method. The main source material for steelmaking is Bessemer cast iron and steel scrap. Steel is subject to heat treatment according to the regime: normalization at a temperature of 950 ° C; quenching at a temperature of 840-860 ° C in oil; tempering at a temperature of 160-200 ° C.
