Abstract
Description
Изобретение относится к области металлургии, в частности, к составам сталей, которые могут быть использованы в производстве оборудования пищевой, химической, нефтяной и газовой промьшшенности.The invention relates to the field of metallurgy, in particular, to compositions of steels that can be used in the manufacture of equipment for the food, chemical, oil and gas industries.
Известна стать, содержащая, мас.%: углерод 0,03-0,08; кремний 0,1-0,3; марганец 0,1-0,3; хром 11,0-14,5; никель 5,0-8,0; медь 1,0-2,5; железо остальное [1]. Предел прочности такой стали при растяжении составляет 92-95 кг/мм2.It is known to become, containing, wt.%: Carbon 0.03-0.08; silicon 0.1-0.3; manganese 0.1-0.3; chrome 11.0-14.5; nickel 5.0-8.0; copper 1.0-2.5; iron the rest [1]. The tensile strength of such steel is 92-95 kg / mm 2 .
Задачей изобретения является повышение прочности стали.The objective of the invention is to increase the strength of steel.
Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, хром, никель, медь, железо, дополнительно содержит цирконий, серебро, ванадий, при следующем соотношении компонентов, мас.%: углерод 0,03-0,08; кремний 0,2-0,3; марганец 0,2-0,3; хром 14,5-15,5, никель 7,0-8,0; медь 2,6-2,9; цирконий 0,1-0,2, серебро 0,001-0,002; ванадий 0,6-0,8;, железо остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, nickel, copper, iron, additionally contains zirconium, silver, vanadium, in the following ratio of components, wt.%: Carbon 0.03-0.08; silicon 0.2-0.3; manganese 0.2-0.3; chrome 14.5-15.5, nickel 7.0-8.0; copper 2.6-2.9; zirconium 0.1-0.2, silver 0.001-0.002; vanadium 0.6-0.8 ;, iron the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
ТаблицаTable
В составе стали компоненты проявляют себя следующим образом. Хром и никель обеспечивают повышенную твердость и коррозионную стойкость стали. Ванадий упрочняет твердый раствор. Медь улучшает металлическою структуру сплава, увеличивает пластичность. Серебро придает структуре стали мелкозернистость. Цирконий благоприятно влияет на состояние границ зерен, упрочняя их.In the steel composition, the components manifest themselves as follows. Chrome and nickel provide increased hardness and corrosion resistance of steel. Vanadium strengthens the solid solution. Copper improves the metal structure of the alloy, increases ductility. Silver makes the steel structure finely grained. Zirconium favorably affects the state of grain boundaries, strengthening them.
Сталь может быть выплавлена в индукционных закрытых (вакуумных) печах Основной исходный материал для выплавки стали - стальной лом, специально приготовленная шихта. Сталь подлежит термической обработке по режиму, закалка при температуре 780-800°С в масло с последующим отпуском при температуре 160-220°С.Steel can be smelted in induction closed (vacuum) furnaces. The main source material for steelmaking is steel scrap, a specially prepared charge. Steel is subject to heat treatment according to the regime, quenching at a temperature of 780-800 ° C in oil, followed by tempering at a temperature of 160-220 ° C.
