Abstract
Description
Изобретение относится к области металлургии, в частности к составам сталей, которые могут быть использованы в автомобильной промышленности.The invention relates to the field of metallurgy, in particular to compositions of steels that can be used in the automotive industry.
Известна сталь, содержащая, мас.%: углерод 0,12-0,15; кремний 0,01-0,1; марганец 0,3-0,6; хром 2,0-2,5; алюминий 0,005-0,04; иттрий 0,0005-0,01; медь 0,01-0,25; барий 0,0005-0,01; железо - остальное [1].Known steel containing, wt.%: Carbon 0.12-0.15; silicon 0.01-0.1; manganese 0.3-0.6; chrome 2.0-2.5; aluminum 0.005-0.04; yttrium 0.0005-0.01; copper 0.01-0.25; barium 0.0005-0.01; iron - the rest [1].
Задачей изобретения является повышение прочности и пластичности стали.The objective of the invention is to increase the strength and ductility of steel.
Технический результат достигается тем, что в стали, содержащей углерод, кремний, марганец, хром, алюминий, иттрий, медь, барий, железо, компоненты находятся при следующем соотношении, мас.%: углерод 0,2-0,4; кремний 0,2-0,4; марганец 0,3-0,5; хром 0,3-0,5; алюминий 0,1-0,15; иттрий 0,1-0,3; медь 1,5-2,5; барий 0,008-0,012; железо - остальное.The technical result is achieved by the fact that in steel containing carbon, silicon, manganese, chromium, aluminum, yttrium, copper, barium, iron, the components are in the following ratio, wt.%: Carbon 0.2-0.4; silicon 0.2-0.4; manganese 0.3-0.5; chrome 0.3-0.5; aluminum 0.1-0.15; yttrium 0.1-0.3; copper 1.5-2.5; barium 0.008-0.012; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В стали компоненты проявляют себя следующим образом. Хром стабилизирует карбиды. Медь упрочняет твердый раствор. Алюминий, иттрий и барий выполняют функцию раскислителей, способствуют измельчению зерна.In steel, the components manifest themselves as follows. Chrome stabilizes carbides. Copper strengthens the solid solution. Aluminum, yttrium and barium act as deoxidizers, contribute to the grinding of grain.
Сталь может быть выплавлена кислым конвертерным (на кислородном дутье) способом. Исходный материал для выплавки стали - бессемеровский чугун и стальной лом.Steel can be smelted using an acid converter (oxygen blast) process. The starting material for steelmaking is Bessemer cast iron and steel scrap.
Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.Heat treatment of steel includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
