Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сталей, используемых в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels used in mechanical engineering.
Известна сталь, содержащая, мас. %: углерод 0,08-0,18; кремний 0,3-1,1; марганец 0,5-1,5; хром 0,5-1,1; медь 0,2-0,6; никель 0,3-0,8; кобальт 0,05-0,12; ванадий 0,02-0,12; ниобий 0,01-0,06; железо - остальное [1].Known steel containing, by weight. %: carbon 0.08-0.18; silicon 0.3-1.1; manganese 0.5-1.5; chrome 0.5-1.1; copper 0.2-0.6; nickel 0.3-0.8; cobalt 0.05-0.12; vanadium 0.02-0.12; niobium 0.01-0.06; iron - the rest [1].
Задача изобретения - повышение прочности стали.The objective of the invention is to increase the strength of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, медь, никель, кобальт, ванадий, ниобий, железо, дополнительно включает празеодим, вольфрам и бор при следующем соотношении компонентов, мас. %: углерод 1,0-1,1; кремний 0,3-0,5; марганец 3,5-3,7; хром 0,2-0,3; медь 0,8-1,2; никель 0,8-1,4; кобальт 0,2-0,3; ванадий 0,2-0,3; ниобий 0,2-0,3; празеодим 2,2-2,4; вольфрам 0,2-0,3; бор 0,05-0,1; железо - остальное. В таблице приведены составы стали.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, copper, nickel, cobalt, vanadium, niobium, iron, further includes praseodymium, tungsten and boron in the following ratio of components, wt. %: carbon 1.0-1.1; silicon 0.3-0.5; manganese 3.5-3.7; chrome 0.2-0.3; copper 0.8-1.2; nickel 0.8-1.4; cobalt 0.2-0.3; vanadium 0.2-0.3; niobium 0.2-0.3; praseodymium 2.2-2.4; tungsten 0.2-0.3; boron 0.05-0.1; iron is the rest. The table shows the compositions of steel.
Хром, медь, никель, кобальт, молибден, ниобий, ванадий, вольфрам, празеодим, бор обеспечивают повышенную прочность сплава. Никель улучшает металлическую основу стали. Ниобий, кобальт, медь, ванадий препятствуют возникновению и развитию трещин при механических нагрузках.Chrome, copper, nickel, cobalt, molybdenum, niobium, vanadium, tungsten, praseodymium, boron provide increased alloy strength. Nickel improves the metal base of steel. Niobium, cobalt, copper, vanadium prevent the occurrence and development of cracks under mechanical stress.
Сталь может быть выплавлена в электропечах. Основной исходный материал для выплавки стали - стальной лом, специально приготовленная шихта. Сталь подлежит термической обработке по режиму: закалка при температуре 780-800°С в масло с последующим отпуском при температуре 160-220°С.Steel can be smelted in electric 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.
