Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам стали, которая может быть использована в автомобильной промышленности.The invention relates to the field of ferrous metallurgy, in particular to compositions of steel that can be used in the automotive industry.
Известна сталь, содержащая, мас.%: углерод 0,02-0,1; кремний ≤0,6; марганец 1,5-2,5; никель 0,01-2,0; ванадий 0,001-0,1; ниобий ≤0,01; азот ≤0,006; празеодим 0,0001-0,02; железо остальное [1].Known steel containing, wt.%: Carbon 0.02-0.1; silicon ≤0.6; manganese 1.5-2.5; nickel 0.01-2.0; vanadium 0.001-0.1; niobium ≤0.01; nitrogen ≤0.006; praseodymium 0.0001-0.02; 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 в стали, содержащей углерод, кремний, марганец, никель, ванадий, ниобий, азот, празеодим, железо, компоненты находятся при следующем соотношении, мас.%: углерод 0,08-0,1; кремний 0,2-0,25; марганец 0,2-0,25; никель 2,5-3,0; ванадий 0,2-0,25; ниобий 0,1-0,15; азот 0,001-0,002; празеодим 0,6-0,75; железо остальное.The technical result is achieved in that in a steel containing carbon, silicon, manganese, nickel, vanadium, niobium, nitrogen, praseodymium, iron, the components are in the following ratio, wt.%: Carbon 0.08-0.1; silicon 0.2-0.25; manganese 0.2-0.25; nickel 2.5-3.0; vanadium 0.2-0.25; niobium 0.1-0.15; nitrogen 0.001-0.002; praseodymium 0.6-0.75; iron the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В составе стали компоненты проявляют себя следующим образом. Ниобий, никель и ванадий повышают прочность сплава. Ванадий увеличивает вязкость стали. В химически связанном состоянии с ванадием и ниобием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали. Празеодим способствуют измельчению зерна, повышению прочности стали.In the steel composition, the components manifest themselves as follows. Niobium, nickel and vanadium increase the strength of the alloy. Vanadium increases the viscosity of steel. In a chemically bound state with vanadium and niobium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel. Praseodymium contribute to grinding grain, increasing the strength of steel.
Выплавка стали может быть проведена в вакуумной индукционной печи. Разливка стали осуществляется при температуре 1550-1570°C в слитки, которые в течение 1 ч выдерживают в плавильной камере, а затем охлаждают на воздухе. Термическая обработка стали включает закалку при температуре 850°C в масло и отпуск при температуре 530°C.Steel smelting can be carried out in a vacuum induction furnace. Steel is cast at a temperature of 1550-1570 ° C into ingots, which are kept in a melting chamber for 1 hour and then cooled in air. Heat treatment of steel involves quenching at 850 ° C in oil and tempering at 530 ° C.
