Alloy 625 / UNS N06625 / W.NR. 2.4856

Tlhaloso

Alloy 625 ke alloy ea nickel-chromium-molybdenum e sebelisetsoang matla a eona a phahameng, ho tiea ho phahameng le ho hanyetsa ha kutu ho hoholo. Matla a alloy 625 a tsoa ho matla a thata a molybdenum le niobium ho matrix a eona a nickel-chromium. Leha alloy e ile ea ntlafatsoa bakeng sa matla a mocheso o phahameng, sebopeho sa eona se kopantsoeng haholo le sona se fana ka boemo ba bohlokoa ba ho hanyetsa kutu ka kakaretso.

Liindasteri le Likopo

Alloy 625 e sebelisoa liindastering tse fapaneng, ho kenyeletsoa likoloi, tsa metsing, tsa sefofane, oli le khase, ts'ebetso ea lik'hemik'hale le nyutlelie. Lisebelisoa tse tloaelehileng tsa ho qetela li kenyelletsa li-exchanger tsa mocheso, li-bellows, manonyeletso a ho atolosa, lisebelisoa tsa motlakase, li-fasteners, li-fittings tse potlakileng le lisebelisoa tse ling tse ngata tse hlokang matla le khanyetso khahlanong le libaka tse mabifi tse senyang.

Ho hanyetsa Corrosion

Alloy 625 e na le khanyetso e ntle ea oxidation le ho phahamisa mocheso o phahameng. Ka 1800 ° F, khanyetso ea sekhahla e fetoha ntho ea bohlokoa tšebeletsong. E phahametse lisebelisoa tse ling tse ngata tsa mocheso o phahameng tlas'a mocheso oa cyclic le maemo a pholileng. Motsoako oa likarolo tse kopantsoeng ka har'a alloy 625 e o thusa ho mamella mefuta e mengata e fapaneng ea tikoloho e senyang haholo. Ho batla ho se na tlhaselo libakeng tse bobebe, joalo ka metsi a hloekileng le a leoatle, tikoloho ea pH e sa nke lehlakore, le mecha ea litaba ea alkaline. Likahare tsa chromium tsa motsoako ona li etsa hore ho be le khanyetso e phahameng ho tikoloho ea oxidizing. Lintho tse phahameng tsa molybdenum li etsa hore alloy 625 e se ke ea hlola e e-ba le likoti le likoti.

Thepa le Phekolo ea Mocheso

Alloy 625 e ka thehoa ho sebelisoa mekhoa e fapaneng ea ho sebetsa e batang le e chesang. Alloy 625 e hanela deformation ka mocheso o chesang oa ho sebetsa, ka hona ho hlokahala meroalo e phahameng ho theha thepa. Mohaho o chesang o lokela ho etsoa ka har'a mocheso oa 1700 ° ho isa ho 2150 ° F. Nakong ea ho sebetsa ho batang, mosebetsi oa thepa o thatafala ka potlako ho feta litšepe tse tloaelehileng tsa austenitic. Alloy 625 e na le liphekolo tse tharo tsa mocheso: 1) tharollo ea annealing ka 2000/2200 ° F le ho tima moea kapa kapele, 2) annealing 1600/1900 ° F le ho tima moea kapa kapele le 3) ho imolla khatello ea maikutlo ho 1100/1500 ° F le moea o tima. . Tharollo annealed (grade 2) thepa e atisa ho sebelisoa bakeng sa likopo tse ka holimo ho 1500 ° F moo ho hanyetsanang le ho qhoma ho leng bohlokoa. Sesebediswa sa Soft-annealed (grade 1) se sebediswa hangata bakeng sa dithempereichara tse tlase mme se na le motswako o nepahetseng ka ho fetisisa wa ho tsitlella le ho phatloha.
