Abstract
Description
Изобретение относится к области черной металлургии, в частности, к составам сплавов на основе железа, которые могут быть использованы для изготовления оборудования химической, нефтяной, текстильной промышленности.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 equipment in the chemical, oil, and textile industries.
Известен сплав на основе железа, содержащий мас. %: углерод 0,02-0,08; кремний 2,5-3,5; марганец 5,0-8,0; хром 17,0-20,0; никель 4,0-6,0; титан 0,05-0,15; азот 0,25-0,45; церий 0,1-0,3; железо - остальное [1].Known alloy based on iron containing wt. %: carbon 0.02-0.08; silicon 2.5-3.5; manganese 5.0-8.0; chromium 17.0-20.0; nickel 4.0-6.0; titanium 0.05-0.15; nitrogen 0.25-0.45; cerium 0.1-0.3; iron - the rest [1].
Задачей изобретения является повышение коррозионной стойкости сплава.The objective of the invention is to increase the corrosion resistance of the alloy.
Технический результат достигается тем, что сплав на основе железа, содержащий кремний, марганец, хром, никель, титан, церий, дополнительно содержит цирконий и германий, при следующем соотношении компонентов, мас. %: кремний 0,2-0,3; марганец 7,5-8,0; хром 23,0-24,0; никель 4,0-6,0; титан 0,04-0,1; церий 0,1-0,13; цирконий 0,3-0,4; германий 0,1-0,15; железо - остальное.The technical result is achieved in that the iron-based alloy containing silicon, manganese, chromium, nickel, titanium, cerium, additionally contains zirconium and germanium, in the following ratio of components, wt. %: silicon 0.2-0.3; manganese 7.5-8.0; chrome 23.0-24.0; nickel 4.0-6.0; titanium 0.04-0.1; cerium 0.1-0.13; zirconium 0.3-0.4; germanium 0.1-0.15; iron is the rest.
В таблице приведены составы сплава.The table shows the alloy compositions.
Коррозионная стойкость сплава (потери в весе при кипячении в 65% растворе HNO3) составит ~ 0,005 г/м2ч для всех приведенных в таблице составов.The corrosion resistance of the alloy (weight loss when boiling in a 65% HNO 3 solution) will be ~ 0.005 g / m 2 h for all the compositions listed in the table.
Хром, никель, цирконий обеспечивают повышенную коррозионную стойкость сплава. Германий, церий, титан препятствуют возникновению и развитию очагов коррозии. Титан улучшает структуру сплава.Chromium, nickel, zirconium provide increased corrosion resistance of the alloy. Germanium, cerium, and titanium prevent the occurrence and development of foci of corrosion. Titanium improves the structure of the alloy.
Сплав может быть выплавлен в электропечах.The alloy can be smelted in electric furnaces.
