Description

Изобретение относится к области черной металлургии, в частности к составам сплавов на основе железа, которые могут быть использованы для изготовления деталей тепловых агрегатов, печей, труб, металлургического оборудования.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 parts of thermal units, furnaces, pipes, metallurgical equipment.

Известен сплав на основе железа, содержащий, мас. %: углерод 0,14-0,2; кремний 0,17-0,37; марганец 0,25-0,55; хром 1,35-1,65; никель 4,0-4,4; вольфрам 0,8-1,2; железо - остальное [1].Known alloy based on iron, containing, by weight. %: carbon 0.14-0.2; silicon 0.17-0.37; manganese 0.25-0.55; chromium 1.35-1.65; nickel 4.0-4.4; tungsten 0.8-1.2; iron - the rest [1].

Задачей изобретения является обеспечение прочности сплава на основе железа в условиях повышенных температур.The objective of the invention is to ensure the strength of the alloy based on iron at elevated temperatures.

Технический результат достигается тем, что сплав на основе железа, содержащий марганец, хром, никель, вольфрам, железо, дополнительно содержит ниобий, цирконий и гафний, при следующем соотношении компонентов, мас. %: марганец 8,5-9,5; хром 3,0-3,4; никель 5,0-5,8; вольфрам 2,8-3,2; ниобий 1,0-1,5; цирконий 0,3-0,8; гафний 0,8-1,2; железо - остальное.The technical result is achieved in that the iron-based alloy containing manganese, chromium, nickel, tungsten, iron, additionally contains niobium, zirconium and hafnium, in the following ratio of components, wt. %: manganese 8.5-9.5; chrome 3.0-3.4; nickel 5.0-5.8; tungsten 2.8-3.2; niobium 1.0-1.5; zirconium 0.3-0.8; hafnium 0.8-1.2; iron is the rest.

В таблице приведены составы сплава на основе железа:The table shows the compositions of the alloy based on iron:
