Description
Изобретение относится к области черной металлургии, а именно к составам сталей, используемых в машиностроении.The invention relates to the field of ferrous metallurgy, and in particular to compositions of steels used in mechanical engineering.
Известна сталь, содержащая, мас.%: углерод 0,55-0,9; кремний 0,1-0,6; марганец 1,3-2,0; хром 0,3-1,0; бор 0,0009-0,002; азот 0,01-0,04; стронций 0,0001-0,02; железо - остальное [1].Known steel containing, wt.%: Carbon 0.55-0.9; silicon 0.1-0.6; manganese 1.3-2.0; chrome 0.3-1.0; boron 0.0009-0.002; nitrogen 0.01-0.04; strontium 0.0001-0.02; iron - the rest [1].
Известна сталь, содержащая, мас.%: углерод 0,25-0,34; кремний 0,4-0,6; марганец 0,6-1,1; хром 0,3-0,5; стронций 0,006-0,01; алюминий 0,01-0,06; магний 0,005-0,05; железо - остальное [2].Known steel containing, wt.%: Carbon 0.25-0.34; silicon 0.4-0.6; manganese 0.6-1.1; chrome 0.3-0.5; strontium 0.006-0.01; aluminum 0.01-0.06; magnesium 0.005-0.05; iron - the rest [2].
Задача изобретения состоит в повышении ударной вязкости и прокаливаемости стали.The objective of the invention is to increase the toughness and hardenability of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, стронций, алюминий, магний, железо, дополнительно содержит бор и медь, при следующем соотношении компонентов, мас.%: углерод 0,2-0,4; кремний 0,1-0,2; марганец 0,5-1,0; хром 0,5-1,0; стронций 0,03-0,05; алюминий 0,4-0,8; магний 0,05-0,1; бор 0,01-0,02; медь 1,0-1,5; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, strontium, aluminum, magnesium, iron, additionally contains boron and copper, with the following ratio of components, wt.%: Carbon 0.2-0.4; silicon 0.1-0.2; manganese 0.5-1.0; chrome 0.5-1.0; strontium 0.03-0.05; aluminum 0.4-0.8; magnesium 0.05-0.1; boron 0.01-0.02; copper 1.0-1.5; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Хром упрочняет твердый раствор. Медь снижает склонность стали к образованию трещин. Алюминий повышает ударную вязкость. Бор, магний и стронций способствуют получению мелкозернистой структуры.Chrome strengthens the solid solution. Copper reduces the tendency of steel to crack. Aluminum increases toughness. Boron, magnesium and strontium contribute to obtaining a fine-grained structure.
Сталь может быть выплавлена в электропечах. Отливки подвергают закалке с температурой 860°С в масле, отпуску при температуре 520°С в масле.Steel can be smelted in electric furnaces. The castings are quenched with a temperature of 860 ° C in oil, tempered at a temperature of 520 ° C in oil.
