Incoloy 925 yog ib qho nyuaj ua kom tawv nqaij raws li Fe-Ni-Cr alloy nrog ntxiv ntawm molybdenum, tooj liab, titanium thiab txhuas.Lub alloy muaj lub zog siab thiab zoo heev corrosion kuj nyob rau hauv daim ntawv thov.Cov ntsiab lus npib tsib xee yog txaus los tiv thaiv cov hlau los ntawm corrosion thiab tawg los ntawm chloride ions.Kev sib xyaw ntawm npib tsib xee, molybdenum thiab tooj liab kuj tseem muab cov alloy zoo heev los txo cov tshuaj.Molybdenum pab txhim kho kev tiv thaiv pitting thiab crevice corrosion.Cov chromium tivthaiv ntawm cov alloy muab oxidation tsis kam tiv thaiv ib puag ncig txo.Qhov sib ntxiv ntawm titanium thiab txhuas tuaj yeem ntxiv dag zog rau cov hlau thaum kho cua sov

Carpenter Alloy 925 tau pom zoo rau NACE MR0175.
NWS MR0175
Zoo mechanical zog thiab nws kim heev corrosion kuj.
Nws muaj qhov zoo corrosion kuj rau chloride ion kev nyuaj siab corrosion, hauv zos corrosion thiab ntau yam oxidizing chemical media.
Commonl siv nyob rau hauv roj thiab roj drillinga equioment qhov chaw thiab cov khoom.xws li cov kav dej, li qub, ioint bositioning, cuab yeej ioint packer, kuj siv rau hauv kev tsim khoom ntawm ib co fasteners.
