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 сталь, содержащая углерод, кремний, марганец, никель, ванадий, ниобий, азот, празеодим, железо, дополнительно содержит цинк и родий при следующем соотношении компонентов, мас.% углерод 0,06-0,08; кремний 0,25-0,35; марганец 0,6-1,0; никель 0,6-1,0; ванадий 0,2-0,4; ниобий 0,14-0,2; азот 0,06-0,12; празеодим 0,02-0,04; цинк 0,004-0,006; родий 0,018-0,02; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, nickel, vanadium, niobium, nitrogen, praseodymium, iron, additionally contains zinc and rhodium in the following ratio, wt.% Carbon 0.06-0.08; silicon 0.25-0.35; manganese 0.6-1.0; nickel 0.6-1.0; vanadium 0.2-0.4; niobium 0.14-0.2; nitrogen 0.06-0.12; praseodymium 0.02-0.04; zinc 0.004-0.006; rhodium 0.018-0.02; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В составе стали компоненты проявляют себя следующим образом. Ниобий и ванадий упрочняют твердый раствор. В химически связанном состоянии с ванадием и ниобием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали. Родий способствует дисперсному упрочнению. Хром стабилизирует карбиды. Присутствие празеодима и цинка препятствует росту зерна, при этом празеодим нейтрализует вредное влияние примесей серы. Никель увеличивает прочностные и пластические свойства стали.In the steel composition, the components manifest themselves as follows. Niobium and vanadium harden the solid solution. 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. Rhodium promotes dispersion hardening. Chrome stabilizes carbides. The presence of praseodymium and zinc inhibits grain growth, while praseodymium neutralizes the harmful effects of sulfur impurities. Nickel increases the strength and plastic properties of steel.
Выплавка стали может быть проведена в вакуумной индукционной печи. Разливка стали осуществляется при температуре 1550-1570°С в слитки, которые в течение 1 ч выдерживают в плавильной камере, а затем охлаждают на воздухе. Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.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 includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
