Abstract

Раскрыта мартенситная жаропрочная сталь для использования в котлоагрегатах, характеризующаяся исключительным сочетанием повышенной длительной прочности и превосходного сопротивления окислению при воздействии высоких температур в паросодержащих средах, имеющая следующий химический состав, определенный с помощью расплавления (в вес.%): C: от 0,10 до 0,16, Si: от 0,20 до 0,60, Mn: от 0,30 до 0,80, P: ≤ 0,020, S: ≤ 0,010, Al: ≤ 0,020%, Cr: от 10,5 до 12,00, Mo: от 0,10 до 0,60, V: от 0,15 до 0,30, Ni: от 0,10 до 0,40, B: от 0,008 до 0,015, N: от 0,002 до 0,020, Co: от 1,50 до 3,00, W: от 1,50 до 2,50, Nb: от 0,02 до 0,07, Ti: от 0,001 до 0,020. Остальная часть стали состоит из железа и неизбежных примесей. Сталь нормализуют в течение периода от приблизительно 10 до приблизительно 120 мин в температурном диапазоне от 1050 до 1170°C и охлаждают на воздухе или в воде до комнатной температуры и затем отпускают в течение по меньшей мере 1 ч в температурном диапазоне от 750 до 820°C. Она демонстрирует мартенситную микроструктуру со средним содержанием δ-феррита менее 5 об.%.Revealed martensitic heat-resistant steel for use in boilers, characterized by an exceptional combination of increased long-term strength and excellent resistance to oxidation when exposed to high temperatures in steam-containing environments, having the following chemical composition determined by melting (% by weight): C: from 0.10 to 0.16, Si: from 0.20 to 0.60, Mn: from 0.30 to 0.80, P: ≤ 0.020, S: ≤ 0.010, Al: ≤ 0.020%, Cr: from 10.5 to 12 , 00, Mo: from 0.10 to 0.60, V: from 0.15 to 0.30, Ni: from 0.10 to 0.40, B: from 0.008 to 0.015, N: from 0.002 to 0.020, Co: from 1.50 to 3.00, W: from 1.50 to 2.50, Nb: from 0.02 to 0.07, Ti: from 0.001 to 0.020. The rest of the steel consists of iron and inevitable impurities. The steel is normalized from about 10 to about 120 minutes in the temperature range from 1050 to 1170 ° C and cooled in air or in water to room temperature and then let go for at least 1 hour in the temperature range from 750 to 820 ° C . It exhibits a martensitic microstructure with an average δ-ferrite content of less than 5% by volume.
