Abstract
Description
Изобретение относится к области черной металлургии, в частности, к составам сплавов на основе железа, которые могут быть использованы для изготовления оборудования, эксплуатируемого в условиях агрессивных сред.The invention relates to the field of ferrous metallurgy, in particular, to compositions of alloys based on iron, which can be used for the manufacture of equipment operated in aggressive environments.
Известен коррозионностойкий сплав, содержащий мас. %: углерод 0,03-0,1; кремний 0,3-0,8; марганец 0,1-0,5; хром 27,0-29,0; сера 0,005-0,015; фосфор 0,003-0,009; молибден 0,1-0,5; иттрий 0,01-0,08; сурьма 0,0008-0,002; железо - остальное [1].Known corrosion-resistant alloy containing wt. %: carbon 0.03-0.1; silicon 0.3-0.8; manganese 0.1-0.5; chrome 27.0-29.0; sulfur 0.005-0.015; phosphorus 0.003-0.009; molybdenum 0.1-0.5; yttrium 0.01-0.08; antimony 0.0008-0.002; iron - the rest [1].
Задачей изобретения является повышение коррозионной стойкости сплава.The objective of the invention is to increase the corrosion resistance of the alloy.
Технический результат достигается тем, что коррозионностойкий сплав, содержащий марганец, хром, молибден, иттрий, сурьму, железо, дополнительно содержит теллур, титан и ниобий, при следующем соотношении компонентов, мас. %: марганец 0,3-0,5; хром 31,0-32,0; молибден 0,05-0,07; иттрий 0,03-0,05; сурьма 0,001-0,0012; теллур 0,0001-0,00012; титан 0,02-0,05; ниобий 0,1-0,12; железо - остальное.The technical result is achieved in that the corrosion-resistant alloy containing manganese, chromium, molybdenum, yttrium, antimony, iron, additionally contains tellurium, titanium and niobium, in the following ratio of components, wt. %: manganese 0.3-0.5; chrome 31.0-32.0; molybdenum 0.05-0.07; yttrium 0.03-0.05; antimony 0.001-0.0012; tellurium 0.0001-0.00012; titanium 0.02-0.05; niobium 0.1-0.12; iron is the rest.
В таблице приведены составы сплава. The table shows the alloy compositions.
Скорость коррозии сплава (в водной среде с содержанием Cl' в количестве 10 мг/л при температуре 300°С, давление в автоклаве 8,5 МПа, длительность 75 ч) составит ~ 0,005 мм/г для всех приведенных в таблице составов.The corrosion rate of the alloy (in an aqueous medium with a Cl 'content of 10 mg / L at a temperature of 300 ° C, an autoclave pressure of 8.5 MPa, a duration of 75 hours) will be ~ 0.005 mm / g for all the compositions listed in the table.
Повышение коррозионной стойкости сплава достигается за счет комплексного влияния компонентов, входящих в его состав. Хром, молибден, ниобий повышают коррозионную стойкость сплава. Титан уменьшает количество дефектов структуры сплава. Иттрий, сурьма, теллур препятствуют развитию очагов коррозии в агрессивной среде.Increasing the corrosion resistance of the alloy is achieved due to the complex effect of the components that make up its composition. Chrome, molybdenum, niobium increase the corrosion resistance of the alloy. Titanium reduces the number of defects in the structure of the alloy. Yttrium, antimony, tellurium hinder the development of foci of corrosion in an aggressive environment.
Сплав может быть выплавлен в электропечах.The alloy can be smelted in electric furnaces.
