Description

Известны марки сталей, содержащие 12% хрома с добавками других элементов (ЭИ747, ЭИ748, ЭИ756 и другие).Known steel grades containing 12% chromium with the addition of other elements (EI747, EI748, EI756 and others).

Предлагаема  жаропрочна  нержавеюща  сталь Х12ВМБФР (ЭИ993) отличаетс  от существующих сталей с 12% хрома дополнительным содержанием ниоби  и бора и ограничением по никелю и марганцу (соответственно не более 0,3 и 0,5%).The proposed heat resistant stainless steel H12BMBFR (EI993) differs from existing steels with 12% chromium with an additional content of niobium and boron and a limit of nickel and manganese (respectively, not more than 0.3 and 0.5%).

Сталь ЭИ993 имеет следующий состав в %: углерода 0,10-0,25; кремни  до 0,7; марганца до 0,5; хрома 11 -12; молибдена 0,4-1,5; ванади  0,3-1,0; вольфрама 0,15-0,30; ниоби  0,2-1,0; бора до 0,005; никел  до 0,3; серы и фосфора 0,025.Steel EI993 has the following composition in%: carbon 0.10-0.25; silicon to 0.7; manganese to 0.5; chromium 11 -12; molybdenum 0.4-1.5; vanadium 0.3-1.0; tungsten 0.15-0.30; niobium 0.2-1.0; boron to 0,005; Nickel to 0.3; sulfur and phosphorus 0.025.

Изменение комплекса легирующих элементов и введение определенного предела легировани  стали элемента.ми, вход щими в комплекс, обеспечили получение более высоких характеристик жаропрочности, чем у примен емых марок стали.The change in the complex of alloying elements and the introduction of a certain limit of the alloying of steel by the elements included in the complex provided higher heat resistance characteristics than those used for steel grades.

После термообработки (закалки при 1050-1150°, масло, отпуск при 650-700°) сталь имеет следующие характеристики:After heat treatment (quenching at 1050-1150 °, oil, tempering at 650-700 °), the steel has the following characteristics:

Предмет изобретени Subject invention

Жаропрочна  сталь следующего соста1ва в %: углерода 0,10-0,25; кремни  до 0,7; марганца до 0,5; хрома 11,0-12,0; молибдена 0,4-1,5; вольфрама 0,3-1,0; ванади  0,15-0,30, отличающа с  тем, что, с целью повышени  жаропрочности, в сталь введены ниобий в количестве 0,2-1,0% и бор до 0,005% при ограничении никел  не более 0,3%.Heat resistant steel of the following composition in%: carbon 0.10-0.25; silicon to 0.7; manganese to 0.5; chromium 11.0-12.0; molybdenum 0.4-1.5; tungsten 0.3-1.0; Vanadium 0.15-0.30, characterized in that, in order to increase the heat resistance, niobium in the amount of 0.2-1.0% and boron to 0.005% with a nickel limit of not more than 0.3% are introduced into the steel.
