Description

Изобретение относится к области черной металлургии, в частности, к составам сплавов на основе железа, которые могут быть использованы для изготовления сварочной проволоки.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 welding wire.

Известен сплав на основе железа, содержащий мас. %: углерод 0,02-0,2; кремний 0,05-0,7; марганец 1,0-2,0; хром 16,0-18,0; никель 9,5-11,0; молибден 1,2-1,8; алюминий 0,03-0,1; титан 0,01-0,03; ниобий 0,01-0,05; железо - остальное [1].Known alloy based on iron containing wt. %: carbon 0.02-0.2; silicon 0.05-0.7; manganese 1.0-2.0; chrome 16.0-18.0; nickel 9.5-11.0; molybdenum 1.2-1.8; aluminum 0.03-0.1; titanium 0.01-0.03; niobium 0.01-0.05; iron - the rest [1].

Задачей изобретения является обеспечение прочности сварного соединения из сплава при повышенных температурах.The objective of the invention is to ensure the strength of the welded joint of the alloy at elevated temperatures.

Технический результат достигается тем, что сплав на основе железа, содержащий марганец, хром, никель, молибден, ниобий, железо, дополнительно содержит кобальт и ванадий, при следующем соотношении компонентов, мас. %: марганец 1,0-2,0; хром 16,0-18,0; никель 16,0-20,0; молибден 0,8-1,0; ниобий 0,2-0,3; кобальт 3,0-4,0; ванадий 0,08-0,12; железо - остальное.The technical result is achieved in that the iron-based alloy containing manganese, chromium, nickel, molybdenum, niobium, iron, additionally contains cobalt and vanadium, in the following ratio of components, wt. %: manganese 1.0-2.0; chrome 16.0-18.0; nickel 16.0-20.0; molybdenum 0.8-1.0; niobium 0.2-0.3; cobalt 3.0-4.0; vanadium 0.08-0.12; iron is the rest.

В таблице приведены составы сплава.The table shows the alloy compositions.

Хром, марганец, никель, молибден, ванадий, ниобий, кобальт, иттрий обеспечивают прочность сварного соединения из сплава при повышенных температурах. Ванадий, никель и кобальт увеличивают вязкость сплава, препятствует возникновению и развитию трещин в сварном соединении при механических нагрузках.Chromium, manganese, nickel, molybdenum, vanadium, niobium, cobalt, yttrium provide strength of the welded joint from the alloy at elevated temperatures. Vanadium, nickel and cobalt increase the viscosity of the alloy, prevents the occurrence and development of cracks in the welded joint under mechanical stress.

Сплав может быть выплавлен в электропечах.The alloy can be smelted in electric furnaces.
