Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сталей, которые могут быть использованы в автомобильной промышленности.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels that can be used in the automotive industry.
Известна сталь, содержащая, мас.%: углерод 0,004-0,25; кремний 0,12-0,32; марганец 0,05-0,35; ванадий 2,0-2,1; медь 0,05-0,18; азот 0,001-0,15; железо - остальное [1].Known steel containing, wt.%: Carbon 0,004-0,25; silicon 0.12-0.32; manganese 0.05-0.35; vanadium 2.0-2.1; copper 0.05-0.18; nitrogen 0.001-0.15; iron - the rest [1].
Задача изобретения состоит в повышении прочности стали.The objective of the invention is to increase the strength of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, ванадий, медь, азот, железо, дополнительно включает индий, стронций, цинк, бор, натрий, причем компоненты находятся при следующем соотношении, мас.%: углерод 0,15-0,25; кремний 0,15-0,25; марганец 0,25-0,35; ванадий 3,0-3,6; медь 2,7-3,1; азот 0,001-0,002; индий 0,15-0,25; стронций 0,001-0,002; цинк 0,001-0,002; бор 0,06-0,08; натрий 0,0001-0,0002; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, vanadium, copper, nitrogen, iron, additionally includes indium, strontium, zinc, boron, sodium, and the components are in the following ratio, wt.%: Carbon 0.15 -0.25; silicon 0.15-0.25; manganese 0.25-0.35; vanadium 3.0-3.6; copper 2.7-3.1; nitrogen 0.001-0.002; indium 0.15-0.25; strontium 0.001-0.002; zinc 0.001-0.002; boron 0.06-0.08; sodium 0.0001-0.0002; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В составе стали компоненты проявляют себя следующим образом. Ванадий повышает вязкость и пластичность стали, улучшает ее структуру. Медь повышает пластичность сплава. В химически связанном состоянии с ванадием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали. Бор стабилизирует карбиды. Цинк и натрий способствуют измельчению зерна. Индий регулирует рост зерна. Стронций уменьшает количество газовых включений в сплаве.In the steel composition, the components manifest themselves as follows. Vanadium increases the viscosity and ductility of steel, improves its structure. Copper increases the ductility of the alloy. In a chemically bound state with vanadium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel. Boron stabilizes carbides. Zinc and sodium contribute to the grinding of grain. Indium regulates grain growth. Strontium reduces the amount of gas inclusions in the alloy.
Сталь может быть выплавлена кислым конвертерным способом на кислородном дутье. Основной исходный материал - бессемеровский чугун и стальной лом. Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.Steel can be melted using an acidic converter using oxygen blasting. The main source material is Bessemer cast iron and steel scrap. Heat treatment of steel includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
