Description
Изобретение относится к области металлургии, в частности к составам сталей, которые могут быть использованы в автомобильной промышленности, производстве бытовой техники.The invention relates to the field of metallurgy, in particular to compositions of steels that can be used in the automotive industry, the production of household appliances.
Известна низколегированная сталь, содержащая, мас.%: углерод 0-1,0; кремний 0-3,0; марганец 0-2,0; хром 0-30,0; никель 0-50,0; ванадий 0-1,0; медь 0-5,0; алюминий 0-2,0; азот 0-0,2; цирконий 0-0,3; титан 0-5,0; ниобий 0-5,0; железо - остальное [1].Known low-alloy steel, containing, wt.%: Carbon 0-1.0; silicon 0-3.0; manganese 0-2.0; chrome 0-30.0; nickel 0-50.0; vanadium 0-1.0; copper 0-5.0; aluminum 0-2.0; nitrogen 0-0.2; zirconium 0-0.3; titanium 0-5.0; niobium 0-5.0; iron - 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 низколегированная сталь, содержащая углерод, кремний, марганец, хром, никель, ванадий, медь, алюминий, азот, цирконий, титан, ниобий, железо, дополнительно включает кальций, при следующем соотношении компонентов, мас.%: углерод 0,1-0,2; кремний 0,1-0,3; марганец 0,5-1,0; хром 0,5-1,0; никель 0,5-1,0; ванадий 0,1-0,2; медь 0,5-1,0; алюминий 0,05-1,0; азот 0,05-0,1; цирконий 0,05-0,1; титан 0,05-0,1; ниобий 0,5-1,0; кальций 0,001-0,003; железо - остальное.The technical result is achieved by the fact that low alloy steel containing carbon, silicon, manganese, chromium, nickel, vanadium, copper, aluminum, nitrogen, zirconium, titanium, niobium, iron, additionally includes calcium, in the following ratio, wt.%: Carbon 0.1-0.2; silicon 0.1-0.3; manganese 0.5-1.0; chrome 0.5-1.0; nickel 0.5-1.0; vanadium 0.1-0.2; copper 0.5-1.0; aluminum 0.05-1.0; nitrogen 0.05-0.1; zirconium 0.05-0.1; titanium 0.05-0.1; niobium 0.5-1.0; calcium 0.001-0.003; iron is the rest.
В таблице приведены составы низколегированной стали.The table shows the compositions of low alloy steel.
В составе стали компоненты проявляют себя следующим образом. Хром стабилизирует карбиды. Кальций, ванадий и алюминий выполняют функции раскислителей. Медь и никель улучшают металлическую основу сплава. В химически связанном состоянии с алюминием, титаном, ниобием и ванадием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали.In the steel composition, the components manifest themselves as follows. Chrome stabilizes carbides. Calcium, vanadium and aluminum act as deoxidizers. Copper and nickel improve the metal base of the alloy. In a chemically bound state with aluminum, titanium, niobium and vanadium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel.
Сталь может быть выполнена кислым конвертным способом. Основной исходный материал для выплавки стали - бессемеровский чугун. Отливки подвергают закалке с температурой 860°С в масле, отпуску при температуре 520°С в масле.Steel can be made acidic envelope method. The main source material for steelmaking is Bessemer cast iron. The castings are quenched with a temperature of 860 ° C in oil, tempered at a temperature of 520 ° C in oil.
