Description

Изобретение относится к области черной металлургии, в частности к составам стали, которая может быть использована для изготовления оборудования химической, нефтяной, текстильной и других отраслей промышленности.The invention relates to the field of ferrous metallurgy, in particular to compositions of steel, which can be used for the manufacture of equipment in the chemical, oil, textile and other industries.

Известна коррозионно-стойкая сталь, содержащая 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 steel 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 стали.The objective of the invention is to increase the corrosion resistance of steel.

Технический результат достигается тем, что коррозионно-стойкая сталь, содержащая углерод, кремний, марганец, хром, молибден, иттрий, железо, дополнительно содержит тантал и медь, при следующем соотношении компонентов, мас. %: углерод 0,01-0,02; кремний 0,1-0,2; марганец 0,1-0,5; хром 27,0-29,0; молибден 1,0-3,0; иттрий 0,01-0,08; тантал 0,15-0,3; медь 0,1-0,2; железо - остальное.The technical result is achieved by the fact that corrosion-resistant steel containing carbon, silicon, manganese, chromium, molybdenum, yttrium, iron, additionally contains tantalum and copper, in the following ratio, wt. %: carbon 0.01-0.02; silicon 0.1-0.2; manganese 0.1-0.5; chrome 27.0-29.0; molybdenum 1.0-3.0; yttrium 0.01-0.08; tantalum 0.15-0.3; copper 0.1-0.2; iron is the rest.

В таблице приведены составы стали.The table shows the compositions of steel.

Повышение коррозионной стойкости стали достигается за счет комплексного влияния компонентов, входящих в ее состав. Хром, молибден, тантал обеспечивают повышенную прочность, твердость и коррозионную стойкость стали. Иттрий раскисляет сплав. Медь препятствует возникновению и развитию трещин в стальных изделиях.Increasing the corrosion resistance of steel is achieved due to the complex effect of the components that make up its composition. Chrome, molybdenum, tantalum provide increased strength, hardness and corrosion resistance of steel. Yttrium deoxidizes the alloy. Copper prevents the occurrence and development of cracks in steel products.

Сталь может быть выплавлена в электропечах. Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.Steel can be smelted in electric furnaces. Heat treatment of steel includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
