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 0,2-0,6; кремний 0,8-1,5; марганец 0,4-1,0; хром 22,0-25,0; никель 12,0-15,0; иттрий 0,05-0,5; железо - остальное [1].Known steel containing wt. %: carbon 0.2-0.6; silicon 0.8-1.5; manganese 0.4-1.0; chrome 22.0-25.0; nickel 12.0-15.0; yttrium 0.05-0.5; 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, включающая углерод, кремний, марганец, хром, никель, иттрий, железо, дополнительно содержит кальций, вольфрам, кобальт, медь и рутений, причем компоненты находятся при следующем соотношении, мас. %: углерод 0,3-0,5; кремний 0,3-0,5; марганец 8,5-10,0; хром 21,0-25,0; никель 5,0-10,0; иттрий 0,002-0,003; кальций 0,002-0,003; вольфрам 0,7-1,3; кобальт 0,3-0,5; медь 1,3-1,9; рутений 2,3-3,4; железо - остальное.The technical result is achieved in that the steel, including carbon, silicon, manganese, chromium, nickel, yttrium, iron, additionally contains calcium, tungsten, cobalt, copper and ruthenium, and the components are in the following ratio, wt. %: carbon 0.3-0.5; silicon 0.3-0.5; manganese 8.5-10.0; chrome 21.0-25.0; nickel 5.0-10.0; yttrium 0.002-0.003; calcium 0.002-0.003; tungsten 0.7-1.3; cobalt 0.3-0.5; copper 1.3-1.9; ruthenium 2.3-3.4; iron is the rest.

В таблице приведены составы стали.

Хром, кобальт, медь, вольфрам, рутений и никель обеспечивают прочность сплава. Никель улучшает металлическую основу стали. Рутений препятствует возникновению и развитию трещин при механических воздействиях. Иттрий и кальций раскисляют сплав.Chrome, cobalt, copper, tungsten, ruthenium and nickel ensure the strength of the alloy. Nickel improves the metal base of steel. Ruthenium prevents the occurrence and development of cracks under mechanical stress. Yttrium and calcium deoxidize the alloy.

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.
