Abstract
Description
Изобретение относится к области металлургии, в частности к составам хромомарганцевых сталей, которые могут быть использованы в производстве металлургического оборудования, деталей тепловых агрегатов, печей.The invention relates to the field of metallurgy, in particular to compositions of chromium-manganese steels, which can be used in the production of metallurgical equipment, parts of thermal units, furnaces.
Известна жаростойкая сталь, содержащая, мас.%: углерод <2,0; кремний <2,0; марганец <10,0; хром 7,5-30,0; молибден <5,0; алюминий 0,05-0,5; азот <0,1; ниобий 0,05-3,0; иттрий (РЗМ) 0,005-0,5; бор 0,0005-0,1; никель ≤40,0; железо (и неизбежные примеси) - остальное [1].Heat-resistant steel is known, containing, wt.%: Carbon <2.0; silicon <2.0; manganese <10.0; chrome 7.5-30.0; molybdenum <5.0; aluminum 0.05-0.5; nitrogen <0.1; niobium 0.05-3.0; yttrium (REM) 0.005-0.5; boron 0.0005-0.1; nickel ≤40.0; iron (and inevitable impurities) - the rest [1].
Задачей изобретения является повышение жаростойкости стали.The objective of the invention is to increase the heat resistance of steel.
Технический результат достигается тем, что в составе жаростойкой стали, содержащей углерод, кремний, марганец, хром, молибден, алюминий, азот, ниобий, иттрий, бор, никель, железо, компоненты находятся при следующем соотношении, мас.%: углерод 0,05-0,15; кремний 0,2-0,5; марганец 8,0-12,0; хром 8,0-12,0; молибден 0,3-0,5; алюминий 2,0-2,5; азот 0,05-0,15; ниобий 0,01-0,03; иттрий 0,1-0,3; бор 0,1-0,2, никель 1,0-1,5; железо - остальное.The technical result is achieved by the fact that in the composition of heat-resistant steel containing carbon, silicon, manganese, chromium, molybdenum, aluminum, nitrogen, niobium, yttrium, boron, nickel, iron, the components are in the following ratio, wt.%: Carbon 0.05 -0.15; silicon 0.2-0.5; manganese 8.0-12.0; chrome 8.0-12.0; molybdenum 0.3-0.5; aluminum 2.0-2.5; nitrogen 0.05-0.15; niobium 0.01-0.03; yttrium 0.1-0.3; boron 0.1-0.2, nickel 1.0-1.5; iron is the rest.
В таблице приведены составы жаростойкой стали.The table shows the compositions of heat-resistant steel.
Повышение жаростойкости стали обусловлено комплексным влиянием компонентов, входящих в ее состав. Бор стабилизирует карбиды. Никель, ниобий и молибден упрочняют твердый раствор. Алюминий препятствует росту окалины. В химически связанном состоянии с алюминием и ниобием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали. Иттрий выполняет функцию раскислителя, придает мелкозернистость структуре стали.The increase in heat resistance of steel is due to the complex effect of the components that make up its composition. Boron stabilizes carbides. Nickel, niobium and molybdenum strengthen the solid solution. Aluminum inhibits the growth of scale. In a chemically bound state with aluminum and niobium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel. Yttrium acts as a deoxidizing agent, imparts a fine-grained structure to the steel.
Сталь может быть выплавлена в индукционных закрытых (вакуумных) печах. Основной исходный материал - стальной лом, специально приготовленная шихта. Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.Steel can be smelted in induction closed (vacuum) furnaces. The main source material is steel scrap, a specially prepared mixture. Heat treatment of steel includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
