2. Corrosion Kuj:
Hastelloy C276Renowned rau nws qhov tseeb tsis kam mus rau ntau yam tshuaj txhoj puab heev, suav nrog cov tshuaj acid acid, thiab lwm cov chletic acid, thiab lwm cov chleticide, ua rau muaj txiaj ntsig tshwj xeeb hauv kev siv tshuaj lom neeg.
Hastelloy c -22Muab cov kev tsis txaus siab me ntsis rau cov oxidizing ib puag ncig muaj feem ntau nyob rau hauv cov xwm txheej uas muaj cov kua qaub sib xyaw nrog cov tsiaj oxidizing). Nws tseem tseem tiv taus ntau rau pitting thiab crevice corrosion hauv chloride ib puag ncig piv rau C276.
3. Kev thov:
Hastelloy C276yog dav siv hauv cov ntawv thov uas yuav tsum tau tiv taus cov chaw ua kom muaj chaw hnyav, xws li:
Kev Lag Luam(xws li, reactors, piping tshuab)
Flue Gas Desulfurization (FGD)Tshuab
Kev Nyab Xeeb Tswjcuab tam
Kws Tshuaj(tshwj xeeb tshaj yog cov cuab yeej siv tau ua rau muaj kuab lom ua tau zoo)
Hastelloy c -22yog siv nyob rau hauv cov ntawv thov sib xws tab sis yog nyiam nyob rau hauvNtau txhoj puab heevib puag ncig lossis cov txheej txheem nrogoxidizing tej yamlos yog sib xyaw acids:
Kev Lag Luam
Kws Tshuaj
Cov Kev Siv Marine(Vim tias tau zoo dua rau dej hiav txwv)
Kev Nyab Xeeb Tswjhwm Tshuab
4. Cov Khoom Siv Neeg Kho Tshuab:
Ob yamHastelloy C276thiabHastelloy c -22muaj zog, ruaj, thiab tiv taus ntau kub, tab sisC-22muaj kev ua tau zoo dua nyob rau hauv cov nqe lus ntawm tag nrhooxidation tsis kamthaum ntau dua kub.
Hastelloy C276yog qhov zoo tagnrho rau ib puag ncig nrog ob qho tib sioxidizingthiabtxoCov xwm txheej, thaumC-22yog zoo dua haum rau ib puag ncig uas muajNtau Oxidizing Hais.
5. Nqi:
Hastelloy C276feem ntau ntau dav muaj thiabTsawg Nqipiv rauHastelloy c -22Vim nws li keeb kwm ntev dua ntawm kev siv hauv kev lag luam thiab ntau dua ntau ntau ntau ntau lawm.
Ntsiab lus ntawm qhov sib txawv tseem ceeb:
| Ntiag tug | Hastelloy C276 | Hastelloy c -22 |
|---|---|---|
| Muaj pes tsawg | High Molybdenum, chromium, thiab npib tsib xee | Siab dua chromium, molybdenum, thiab npib tsib xee |
| Corrosion Kuj | Zoo heev hauv kev txo qis thiab oxidizing tej yam kev mob | Zoo dua hauv oxidizing ib puag ncig, tshwj xeeb tshaj yog cov acids |
| Neeg Kho Tshuab Muaj Zog | Zoo heev ntawm kev kub siab | Me ntsis zoo dua oxidation tsis kam |
| Cov Ntawv Thov | Tshuaj lom neeg ua yeeb yam, tswj kev ua qias tuaj, lub zog tiam | Tshuaj lom neeg ua yeeb yam, tshuaj, cov ntawv thov marine |
| Tus nqi | Muaj nqi ntau dua | Feem ntau kim kim |
Hauv kev xaus,Hastelloy C276yog ntau ntau ntau yam thiab siv tau zoo rau ntau cov ntawv thov, thaumHastelloy c -22txawj ntse hauv ntau yam tshwj xeeb, cov tshuaj oxidingly. Qhov kev xaiv ntawm lawv nyob ntawm qhov tshwj xeeb uas yuav tsum tau ua ntawm daim ntawv thov, tshwj xeeb yog cov tshuaj lom neeg thiab qhov kub thiab txias.
