Corrosion Kuj:
Alloy 20: Paub txog nws cov kev tiv thaiv zoo rau cov sulfuric acid, tshwj xeeb tshaj yog ntawm cov kev muaj siab thiab kub. Nws tseem muaj cov khoom zoo rau lwm cov neeg sawv cev corrosive zoo li phosphoric acid, nitric acid, thiab cov organic acids. Txawm li cas los xij, nws tsis tshua muaj kev tiv thaiv rau chloride-induced kev nyuaj siab corrosion tawg piv rau Hastelloy C276.
Hastelloy C276: Cov khoom pov thawj zoo dua kev tiv thaiv cov tshuaj lom neeg muaj kev ntxhov siab, suav nrog cov sulfuric acid, thiab ntau chloricide, thiab ntau yam tsis kam mus pitting thiab crevice corrosion. Nws kuj tseem muaj qhov zoo dua tiv tauschloride-induced kev ntxhov siab corrosion, ua rau nws haum ntau rau ib puag ncig zoo.
Kub Kuj:
Alloy 20: Tuaj yeem tiv taus kub txog ib puag ncig1000 degree f (537 degree)Cov. Thaum tiv taus qhov kub siab, nws tsis yog li cua sov-resistant li Hastelloy C276 hauv kev siv dhau ntau.
Hastelloy C276: Muaj qhov siab tshaj plaws kev pabcuam kub, tuaj yeem tiv thaiv kom sov txog1040 degree (1900 degree f), ua rau nws haum rau cov kev siv kub siab heev, tshwj xeeb tshaj yog cov tshuaj lom neeg siab ua haujlwm.
Cov Khoom Siv Neeg Kho Tshuab:
Alloy 20: Muaj lub zog zoo thiab tawv. Nws cov yam ntxwv txhua yam yog feem ntau rau cov ntawv thov feem ntau, tab sis nws yuav tsis muaj zog li hastelloy c276 hauv qhov chaw siab.
Hastelloy C276: Paub txog nws lub zog zoo thiab kev nruj heev, tshwj xeeb tshaj yog thaum muaj kev kub ntxhov thiab hauv huab surerosive ib puag ncig. Nws tswj hwm nws cov khoom siv cov khoom siv thaum nce qhov kub, ua rau cov khoom nyiam hauv kev lag luam xws li kev ua yeeb yam thiab aerospace.
Cov Ntawv Thov:
Alloy 20: Feem ntau yog siv hauv kev tsim tshuaj, tshwj xeeb tshaj yog nyob rau hauv kev tsim khoom ntawm cov cuab yeej nthuav tawm cov sulfuric acid, nrog rau kev tsim khoom noj, thiab tshuaj xyuas kev tswjfwm.
Hastelloy C276: Feem ntau siv nyob rau hauv cov khoom siv tau xav tau ntau, suav nrog cov tshuaj lom neeg ua noj, ib qho chaw muaj dej hiav txwv, ib puag ncig ntawm kev ua kom haum thiab muaj huab cua kub. Nws tau dav siv rau reactors, kev sib pauv cua sov, thiab lwm yam tseem ceeb.
Nqi:
Alloy 20: Feem ntau tsis kim tshaj hastelloy c276, raws li nws yog qhov tsis tshua muaj ntau yam nrog cov roj muaj nqis uas kim dua molybdenum thiab tungsten.
Hastelloy C276: Feem ntau kim vim nws cov ntsiab lus ntau dua ntawm cov khoom kim dua xws li Molybdenum, Tungsten, thiab Nickel. Cov kev ua tau zoo tshaj plaws hauv cov chaw hnyav tsis zoo rau cov nqi siab dua rau cov ntawv thov corrosion tsis kam.
