Cov ncauj lus kom ntxaws alloy tawg
1. Uncal N06625 (Alloy 625) -} Cov khoom siv ua haujlwm ntau yam
Qhov no yog ib qho ntawm feem ntau siv nickel -} Raws li alloys vim nws qhov tshwj xeeb ua ke ntawm cov khoom.
Lub luag haujlwm ntawm Niobium (NB):Niobium ua nrog molybdenum los muab kev txaus ntshaiTshuaj ntxiv dag zog.
Corrosion Kuj:
Zoo heev rau pitting thiab corrice corrosion hauv chloride ions.
Heev tiv taus ntau ntau cov acids, alkalis, thiab ntsev.
Oxidation zoo tiv thaiv nyob rau ntawm qhov kub.
Cov Khoom Siv Neeg Kho Tshuab:
Saib xyuas lub zog siab thiab tawv los ntawm cov huab cua txias txias txog qhov kub siab.
Nws rog rog yog ib qho siab tshaj plaws ntawm txhua lub weatrought alloys.
