Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сталей, которые могут быть использованы в производстве насосно-компрессорного оборудования.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels that can be used in the production of tubing equipment.
Известна сталь, содержащая мас. %: углерод 0,15-0,45; кремний 1,5-2,2; марганец 0,5-0,8; хром 25,0-28,0; алюминий 0,15-0,3; никель 6,0-21,0; цирконий 0,08-0,12; медь 0,5-1,0; железо - остальное [1].Known steel containing wt. %: carbon 0.15-0.45; silicon 1.5-2.2; manganese 0.5-0.8; chrome 25.0-28.0; aluminum 0.15-0.3; nickel 6.0-21.0; zirconium 0.08-0.12; copper 0.5-1.0; iron - the rest [1].
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, алюминий, никель, цирконий, медь, железо, дополнительно содержит гафний, молибден и натрий, причем компоненты находятся при следующем соотношении, мас. %: углерод 0,3-0,5; кремний 1,0-1,5; марганец 0,5-1,0; хром 23,0-28,0; алюминий 0,05-0,1; никель 20,0-23,0; цирконий 0,03-0,07; медь 1,5-2,0; гафний 0,7-1,1; молибден 0,25-0,35; натрий 0,0003-0,0005; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, chromium, aluminum, nickel, zirconium, copper, iron, additionally contains hafnium, molybdenum and sodium, and the components are in the following ratio, wt. %: carbon 0.3-0.5; silicon 1.0-1.5; manganese 0.5-1.0; chromium 23.0-28.0; aluminum 0.05-0.1; nickel 20.0-23.0; zirconium 0.03-0.07; copper 1.5-2.0; hafnium 0.7-1.1; molybdenum 0.25-0.35; sodium 0.0003-0.0005; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
Хром, молибден и никель обеспечивают прочность и твердость сплава. Никель улучшает металлическую основу стали. Алюминий увеличивает вязкость сплава. Алюминий, гафний, медь препятствуют возникновению и развитию трещин при механических воздействиях. Цирконий и натрий способствуют измельчению зерна.Chrome, molybdenum and nickel provide strength and hardness of the alloy. Nickel improves the metal base of steel. Aluminum increases the viscosity of the alloy. Aluminum, hafnium, copper prevent the occurrence and development of cracks during mechanical stress. Zirconium and sodium contribute to grain refinement.
Сталь может быть выплавлена в электропечах. Сталь подлежит термической обработке по режиму: закалка при температуре 1180°С на воздухе; старение при температуре 750-800°С.Steel can be smelted in electric furnaces. Steel is subject to heat treatment according to the regime: quenching at a temperature of 1180 ° C in air; aging at a temperature of 750-800 ° C.
