Abstract
Description
Изобретение относится к области черной металлургии, в частности, к составам стали, которая может быть использована в энергетическом машиностроении, производстве металлургического оборудования.The invention relates to the field of ferrous metallurgy, in particular, to compositions of steel, which can be used in power engineering, production of metallurgical equipment.
Известна сталь, содержащая мас. %: углерод 0,01-0,12; кремний 0,01-0,05; марганец 0,5-0,8; хром 0,03-0,15; кобальт 0,5-1,0; железо - остальное [1].Known steel containing wt. %: carbon 0.01-0.12; silicon 0.01-0.05; manganese 0.5-0.8; chromium 0.03-0.15; cobalt 0.5-1.0; iron - the rest [1].
Задачей изобретения является повышение термостойкости стали.The objective of the invention is to increase the heat resistance of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, кобальт, железо, дополнительно содержит медь, серебро, гафний, гадолиний, при следующем соотношении компонентов, мас. %: углерод 0,05-0,15; кремний 0,05-0,1; марганец 7,5-8,0; хром 0,1-0,3; кобальт 1,3-1,7; медь 1,1-1,5; серебро 0,01-0,03; гафний 4,7-5,1; гадолиний 2,7-3,1; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, cobalt, iron, additionally contains copper, silver, hafnium, gadolinium, in the following ratio of components, wt. %: carbon 0.05-0.15; silicon 0.05-0.1; manganese 7.5-8.0; chrome 0.1-0.3; cobalt 1.3-1.7; copper 1.1-1.5; silver 0.01-0.03; hafnium 4.7-5.1; gadolinium 2.7-3.1; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Кобальт улучшает металлическую основу сплава. Хром, марганец, гафний тормозят снижение прочности стали при нагреве, повышают термостойкость стали. Серебро, медь обеспечивает равномерный прогрев и охлаждение стали. Кобальт, гафний, гадолиний препятствуют возникновению и развитию трещин при перепадах температур.Cobalt improves the metal base of the alloy. Chromium, manganese, hafnium inhibit the decrease in the strength of steel during heating, increase the heat resistance of steel. Silver, copper provides uniform heating and cooling of steel. Cobalt, hafnium, gadolinium prevent the occurrence and development of cracks at temperature extremes.
Сталь может быть выплавлена в электропечах. Термическая обработка стали включает нагрев до температуры 1020-1100°С и закалку в воде.Steel can be smelted in electric furnaces. Heat treatment of steel includes heating to a temperature of 1020-1100 ° C and quenching in water.
