Abstract
Description
Изобретение относится к области металлургии, а именно к составам сталей, которые могут быть использованы в автомобилестроении.The invention relates to the field of metallurgy, and in particular to compositions of steels that can be used in the automotive industry.
Известна сталь, содержащая мас.%: углерод 0,2-2,5; кремний ≤0,1; марганец 0,1-1,5; хром 2,0-20,0; ванадий 0,01-5,0; РЗМ 0,001-0,6; кальций 0,002-0,01; азот ≤0,02; бор 0,001-0,05; молибден 0,1-5,0; кобальт 1,0-20,0; медь 0,25-4,0; - остальное [1].Known steel containing wt.%: Carbon 0.2-2.5; silicon ≤0.1; manganese 0.1-1.5; chrome 2.0-20.0; vanadium 0.01-5.0; REM 0.001-0.6; calcium 0.002-0.01; nitrogen ≤0.02; boron 0.001-0.05; molybdenum 0.1-5.0; cobalt 1.0-20.0; copper 0.25-4.0; - the rest [1].
Задачей изобретения является повышение прочности стали.The objective of the invention is to increase the strength of steel.
Технический результат достигается тем, что в стали, содержащей углерод, кремний, марганец, хром, ванадий, РЗМ, кальций, азот, бор, молибден, кобальт, медь, железо, компоненты находятся при следующем соотношении, мас.%: углерод 0,8-1,2; кремний 0,2-0,6; марганец 0,4-0,8; хром 0,4-0,8; ванадий 0,1-0,2; РЗМ 0,1-0,2; кальций 0,005-0,01; азот 0,05-0,1; бор 0,04-0,08; молибден 3,0-4,0; кобальт 0,8-1,6; медь 0,2-0,4; железо - остальное.The technical result is achieved in that in steel containing carbon, silicon, manganese, chromium, vanadium, rare-earth metals, calcium, nitrogen, boron, molybdenum, cobalt, copper, iron, the components are in the following ratio, wt.%: Carbon 0.8 -1.2; silicon 0.2-0.6; manganese 0.4-0.8; chrome 0.4-0.8; vanadium 0.1-0.2; REM 0.1-0.2; calcium 0.005-0.01; nitrogen 0.05-0.1; boron 0.04-0.08; molybdenum 3.0-4.0; cobalt 0.8-1.6; copper 0.2-0.4; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Повышение прочности стали достигается за счет комплексного влияния компонентов, входящих в ее состав. Хром и бор стабилизируют карбиды, придают стали необходимую твердость. Молибден, кобальт, медь упрочняют твердый раствор. В химически связанном состоянии, азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали. Ванадий, кальций и РЗМ выполняют функцию раскислителей, способствуют образованию мелкозернистой структуры стали.Increasing the strength of steel is achieved due to the complex effect of the components that make up its composition. Chrome and boron stabilize carbides, give the steel the necessary hardness. Molybdenum, cobalt, copper harden the solid solution. In a chemically bound state, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel. Vanadium, calcium, and rare-earth metals act as deoxidizers and contribute to the formation of a fine-grained steel structure.
Сталь может быть выплавлена в индукционных вакуумных печах. Основной исходный материал для выплавки стали - стальной лом, специально приготовленная шихта.Steel can be smelted in induction vacuum furnaces. The main source material for steelmaking is steel scrap, a specially prepared charge.
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.
