Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам сталей, которые могут быть использованы в автомобильной промышленности.The invention relates to the field of ferrous metallurgy, and in particular to compositions of steels that can be used in the automotive industry.
Известна сталь, содержащая, мас.%: углерод 0,001-0,006; кремний 0,1-1,0; марганец 0,1-1,0; хром 20,0-24,0; алюминий 3,5-4,5; азот 0,001-0,005; молибден 0,5-1,5; иттрий 0,03-0,05; железо - остальное [1]. Работа развития трещин такой стали составляет 9,6 кгм/см2.Known steel containing, wt.%: Carbon 0,001-0,006; silicon 0.1-1.0; manganese 0.1-1.0; chrome 20.0-24.0; aluminum 3.5-4.5; nitrogen 0.001-0.005; molybdenum 0.5-1.5; yttrium 0.03-0.05; iron - the rest [1]. The crack development work of such steel is 9.6 kgm / cm 2 .
Задача изобретения - увеличение работы развития трещин стали.The objective of the invention is to increase the work of the development of cracks in steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, алюминий, молибден, иттрий, дополнительно содержит ванадий при следующем соотношении компонентов, мас.%: углерод 0,004-0,006; кремний 0,004-0,006; марганец 0,02-0,03, хром 0,1-0,15; алюминий 1,7-2,3; молибден 0,8-1,2; иттрий 0,2-0,3; ванадий 0,4-0,6, железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, aluminum, molybdenum, yttrium, additionally contains vanadium in the following ratio of components, wt.%: Carbon 0,004-0,006; silicon 0.004-0.006; manganese 0.02-0.03; chromium 0.1-0.15; aluminum 1.7-2.3; molybdenum 0.8-1.2; yttrium 0.2-0.3; vanadium 0.4-0.6, iron - the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В составе стали компоненты проявляют себя следующим образом. Хром и марганец стабилизируют карбиды. Молибден и ванадий упрочняют твердый раствор, препятствуют возникновению трещин при ударе. Алюминий способствует раскислению стали, повышая, тем самым, ее вязкость и пластичность. Иттрий способствует измельчению зерна.In the steel composition, the components manifest themselves as follows. Chrome and manganese stabilize carbides. Molybdenum and vanadium strengthen the solid solution, prevent cracking upon impact. Aluminum contributes to the deoxidation of steel, thereby increasing its viscosity and ductility. Yttrium promotes grain refinement.
Сталь может быть выплавлена в электропечах. Термическая обработка стали включает закалку при температуре 850°C в масло и отпуск при температуре 530°C.Steel can be smelted in electric furnaces. Heat treatment of steel involves quenching at 850 ° C in oil and tempering at 530 ° C.
