INCOLOY 825 (UNS N08825 / NS142)
Kopo
Alloy 825 ke motsoako oa nickel-iron-chromium oa austenitic hape o hlalosoang ke litlatsetso tsa molybdenum, koporo le titanium. E ile ea ntlafatsoa ho fana ka khanyetso e ikhethang tikolohong e mengata e senyang, ka bobeli oxidizing le ho fokotsa.
Alloy 825 e ile ea ntlafatsoa ho fana ka khanyetso e ikhethang libakeng tse ngata tse senyang, tse etsang oxidizing le ho fokotsa. Ka mefuta ea nickel e pakeng tsa 38% -46%, sehlopha sena se bonts'a khanyetso e matla ea khatello ea maikutlo (SCC) e bakoang ke chloride le alkalis. Likahare tsa nickel li lekane bakeng sa ho hanyetsa chloride-ion stress-corrosion cracking. Nickel, mmoho le molybdenum le koporo, e boetse e fana ka khanyetso e ikhethang ho fokotsa maemo a kang a nang le sulfuric le phosphoric acid.
Likahare tsa chromium le molybdenum li boetse li fana ka khanyetso e ntle ea likoti libakeng tsohle ntle le litharollo tse matla tsa oxidizing chloride. E sebelisoa e le lisebelisoa tse sebetsang libakeng tse fapaneng tse fapaneng tsa ts'ebetso, alloy 825 e boloka thepa e ntle ea mochini ho tloha mocheso oa cryogenic ho fihla ho 1,000 ° F.
Ho eketsoa ha titanium ho tsitsisa Alloy 825 khahlano le ts'usumetso e maemong a sosobaneng e etsa hore motsoako o se ke oa hlola o hlaseloa ke li-intergranular ka mor'a ho pepesehela mocheso ka mefuta e fapaneng e ka susumetsang litšepe tse sa tsitsang. Ho etsoa ha Alloy 825 ho tloaelehile ka li-alloys tsa nickel-base, tse nang le thepa e ka etsoang habonolo le ho cheseha ka mekhoa e fapaneng.
Sesebelisoa sena se na le sebopeho se setle haholo, se tloaelehileng sa li-alloys tsa nickel-base, tse lumellang thepa hore e kobehe ho radii e nyane haholo. Annealing ka mor'a ho kobeha ha ho hlokahale hangata.
E tšoana le alloy 800 empa e ntlafalitse ho hanyetsa ho bola ha metsi. E na le khanyetso e ntle ho li-acid tse fokotsang le ho oxidizing, ho phatloha ha khatello ea maikutlo, le tlhaselo ea sebakeng se kang pitting le crevice corrosion. Alloy 825 e hanyetsana haholo le sulfuric le phosphoric acid. Alloy ena ea tšepe ea nickel e sebelisetsoa ho lokisa lik'hemik'hale, lisebelisoa tsa taolo ea tšilafalo, lipeipi tsa oli le khase, ho lokisa mafura a nyutlelie, tlhahiso ea asiti le lisebelisoa tsa ho kha.
