Description
Изобретение относится к области металлургии и касается составов сплавов, которые могут быть использованы для изготовления деталей песчаных насосов, мельниц.The invention relates to the field of metallurgy and relates to alloy compositions that can be used for the manufacture of parts for sand pumps, mills.
Известен сплав, содержащий, мас. %: углерод более 4,0; хром 25,0-45,0; ниобий 0-5,0; бор 0-2,0; железо - остальное [1].Known alloy containing, by weight. %: carbon more than 4.0; chrome 25.0-45.0; niobium 0-5.0; boron 0-2.0; iron - the rest [1].
Задачей изобретения является повышение твердости сплава.The objective of the invention is to increase the hardness of the alloy.
Технический результат достигается тем, что сплав, включающий углерод, хром, ниобий, бор, железо, дополнительно содержит азот, причем компоненты находятся при следующем соотношении, мас. %: углерод 3,0-3,6; хром 50,0-52,0; ниобий 1,3-1,7; бор 0,1-0,2; азот 0,0002-0,0003; железо - остальное.The technical result is achieved in that the alloy comprising carbon, chromium, niobium, boron, iron, additionally contains nitrogen, and the components are in the following ratio, wt. %: carbon 3.0-3.6; chrome 50.0-52.0; niobium 1.3-1.7; boron 0.1-0.2; nitrogen 0.0002-0.0003; iron is the rest.
В таблице приведены составы сплава.The table shows the alloy compositions.
Хром обеспечивает повышенную твердость и коррозионную стойкость сплава. Бор стабилизирует карбиды. Ниобий упрочняет твердый раствор.Chromium provides increased hardness and corrosion resistance of the alloy. Boron stabilizes carbides. Niobium strengthens the solid solution.
