Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сталей, которые могут быть использованы в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels that can be used in mechanical engineering.
Известна сталь, содержащая, мас.%: углерод 0,1-0,15; кремний 0,2-0,5; марганец 0,2-0,3; хром 4,5-6,0; иттрий 0,05-0,1; медь 0,1-0,3; кальций 0,01-0,05; железо - остальное [1].Known steel containing, wt.%: Carbon 0.1-0.15; silicon 0.2-0.5; manganese 0.2-0.3; chrome 4.5-6.0; yttrium 0.05-0.1; copper 0.1-0.3; calcium 0.01-0.05; iron - the rest [1].
Задачей изобретения является снижение расхода хрома при сохранении прочности стали.The objective of the invention is to reduce the consumption of chromium while maintaining the strength of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, иттрий, медь, кальций, железо, дополнительно содержит кобальт, алюминий, ниобий, ванадий при следующем соотношении компонентов, мас.%: углерод 0,1-0,15; кремний 0,1-0,15; марганец 0,1-0,15; хром 0,1-0,15; иттрий 0,005-0,01; медь 1,8-2,2; кальций 0,0005-0,001; кобальт 0,2-0,3; алюминий 0,005-0,01; ниобий 0,1-0,15; ванадий 0,25-0,35; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, yttrium, copper, calcium, iron, additionally contains cobalt, aluminum, niobium, vanadium in the following ratio of components, wt.%: Carbon 0.1-0, fifteen; silicon 0.1-0.15; manganese 0.1-0.15; chrome 0.1-0.15; yttrium 0.005-0.01; copper 1.8-2.2; calcium 0.0005-0.001; cobalt 0.2-0.3; aluminum 0.005-0.01; niobium 0.1-0.15; vanadium 0.25-0.35; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В составе стали компоненты проявляют себя следующим образом. Медь, ниобий, ванадий, кобальт, хром повышают прочность сплава. Введение в состав стали хрома стабилизирует карбиды. Иттрий, алюминий и кальций выполняют функции раскислителей.In the steel composition, the components manifest themselves as follows. Copper, niobium, vanadium, cobalt, chromium increase the strength of the alloy. The introduction of chromium steel stabilizes carbides. Yttrium, aluminum and calcium act as deoxidizers.
Сталь может быть выплавлена в индукционных закрытых (вакуумных) печах. Основной исходный материал для выплавки стали - стальной лом, специально приготовленная шихта. Сталь подлежит термической обработке по режиму: закалка при температуре 780-800°C в масло с последующим отпуском при температуре 160-220°C.Steel can be smelted in induction closed (vacuum) furnaces. The main source material for steelmaking is steel scrap, a specially prepared charge. Steel is subject to heat treatment according to the regime: quenching at a temperature of 780-800 ° C in oil, followed by tempering at a temperature of 160-220 ° C.
