В качестве базового объекта исследования служил сплав Никель 201, из которого изготовлено оборудование ряда предприятий, специализирующихся на производстве каустической соды. Благодаря устойчивости к воздействию щелочных сред рассматриваемый материал идеально подходит для применения в растворах гидроксида натрия. Однако сплав имеет невысокую твердость, что существенно снижает его износостойкость. Одним из весомых ограничений многотоннажного расходования сплава Никель 201 является его высокая стоимость. В растворах гидроксида натрия различной концентрации (50, 60, 70 и 80 %) проведены испытания образцов трех коррозионностойких материалов (сплав Никель 201, высоколегированная сталь марок 10Х23Н18 и 06ХН28МДТ) при разных температурах (20, 80 и 100 °C). Особенностью этих сталей является значительное содержание хрома и никеля, что обеспечивает им повышенную стойкость при контакте с едкими веществами, а также приемлемую стоимость в сравнении с никелевым сплавом. Установлено, что сталь марки 10Х23Н18 обладает наибольшей коррозионной стойкостью среди трех материалов при комнатной температуре. Этот сплав может быть рекомендован к изготовлению оборудования, применяемого на ранних стадиях производства каустической соды в условиях пониженных температур. В горячих щелочных растворах более стойким является сплав Никель 201. Для каждого материала в оболочке Statgraphics получено уравнение, позволяющее проводить расчетное прогнозирование скорости их коррозии, в том числе при повышенных температурах, характерных для технологических процессов производства каустической соды. Использование такого подхода призвано обеспечить не только значительное повышение долговечности металлического оборудования, но и существенную экономию материальных ресурсов отрасли.</p></abstract><trans-abstract xml:lang="en"><p>Important aspects of the choice of material for the manufacture of equipment operated in caustic solutions at various temperatures are considered. The basic object of the study was the Nickel 201 alloy, from which the equipment of a number of enterprises specializing in the production of caustic soda was made. Due to its resistance to alkaline media, the material in question is ideally suited for use in sodium hydroxide solutions. However, the alloy has a low hardness, which significantly reduces its wear resistance. One of the significant limitations of the high-tonnage consumption of Nickel 201 alloy is its high cost. Samples of three corrosion-resistant materials (Nickel 201 alloy, high-alloy steel grades 10X23H18 and 06KHN28MDT) were tested at different temperatures (20, 80 and 100 °C) in solutions of sodium hydroxide of various concentrations (50, 60, 70 and 80 %). A special feature of these steels is the significant chromium and nickel content, which provides them with increased resistance to contact with caustic substances, as well as an acceptable cost in comparison with a nickel alloy. It was found that steel grade 10X23H18 has the highest corrosion resistance among the three materials at room temperature. This alloy can be recommended for the manufacture of equipment used in the early stages of caustic soda production at low temperatures. In hot alkaline solutions, Nickel 201 alloy is more resistant. For each material in the Statgraphics shell, an equation has been obtained that makes it possible to make a calculated prediction of their corrosion rate, including at elevated temperatures typical of caustic soda production processes. The use of this approach is designed to ensure not only a significant increase in the durability of metal equipment, but also significant savings in the material resources of the industry.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>каустические растворы</kwd><kwd>едкий натр</kwd><kwd>никелевый сплав</kwd><kwd>коррозионностойкие стали</kwd><kwd>охрупчивание</kwd><kwd>оболочка Statgraphics</kwd><kwd>регрессионный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>caustic solutions</kwd><kwd>caustic soda</kwd><kwd>nickel alloy</kwd><kwd>corrosion-resistant steels</kwd><kwd>embrittlement</kwd><kwd>Statgraphics shell</kwd><kwd>regression analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Семенова И.В., Флорианович Г.М., Хоро-шилов А.В.
