Hastelloy C276:
Hastelloy C276 muaj qhov kev pabcuam kub qis dua me ntsis dua li qhov ntsuas kub tsis suav 625, ib puag ncig 1500 degree f (816 degree). Txawm li cas los xij, nws yog qhov muaj zog heev rau cov chaw kub-cuam tshuam rau cov a corrosion tiv taus raws li cov kev mob siab.
4. Cov Khoom Siv Neeg Kho Tshuab
Inconel 625:
Lub zog tensile: Kev kub siab heev-kub tensile zog.
Paib lub zog: Muaj zog thaum muaj kub.
Kev nyuaj: Siab tsis kam rau nkees thiab cua sov-nkees.
Inconel 625 yog ntau dua rau muab lub zog thiab cov qauv kev ntseeg nyob rau kev ntxhov siab thaum nce qhov kub.
Hastelloy C276:
Lub zog tensile: Muaj zog, txawm hais tias tsis yog li inconel 625 ntawm cov chaw kub.
Paib lub zog: Zoo hauv ob qho tib si ambient thiab kub.
Corrosion Kuj: Superior rau inconel 625, tshwj xeeb tshaj yog hauv kev txo qis thiab acidic ib puag ncig.
Hastelloy C276 yog ntau dua rau kev tiv taus kev tiv thaiv ib puag ncig muaj kev txo qis thiab acidic mob, ntau dua li muab lub zog tshaj plaws ntawm lub zog ntawm cov kub.
5. Cov Ntawv Thov
Inconel 625:
Aerospace Cheebtsam (cov cav cav, tso lub tshuab kaw)
