Description
Изобретение относитс к области изыскани материалов дл химического машиностроени , работающих в агрессивных средах.The invention relates to the field of research materials for chemical engineering, working in corrosive environments.
В качестве таковых известны хромо-марганцевые стали.As such, chromium-manganese steels are known.
Предложенна сталь отличаетс от известных составом и обеспечивает повышенные коррозионные и технологичс:ские свойства.The proposed steel differs from the known composition and provides enhanced corrosion and technological properties.
Сталь имеет следующий состав, о/о:Steel has the following composition, o / o:
16-20 11-17 0,2-0,55 ОД-0,7 до 1,0 0,1-0,4 до 0,08 до 0,6 до 0,03 до 0,0216-20 11-17 0.2-0.55 OD-0.7 to 1.0 0.1-0.4 to 0.08 to 0.6 to 0.03 to 0.02
Механические свойства стали:Mechanical properties of steel:
ав, кг/мм бю, «/о ак, кг/см НВ, кг/мм Угол загиба 180°.Av, kg / mm by, “/ o ak, kg / cm HB, kg / mm Bend angle 180 °.
Испытани на межкристаллитную коррозию по методу AM (ГОСТ 6032-58) показали, что образцы стали не обнаруживают склонности к межкристаллитной коррозии. Материал хорошо свариваетс , его сварные соединени не склонны к образованию холодных и гор чих трещин.Testing for intergranular corrosion according to the AM method (GOST 6032-58) showed that steel samples show no tendency to intergranular corrosion. The material is well welded, its welded joints are not prone to the formation of cold and hot cracks.
