Monel 400 alloy (UNS N04400 los yog MCu{2}}.5-1.8 los yog Ni68Cu28Fe) yog ib hom alloy hauv seawater, tshuaj hnyav, ammonia sulfur chloride, hydrogen chloride, ntau yam acidic media xws li sulfuric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid, organic acid, Nickel-raws li alloy khoom nrog zoo corrosion kuj nyob rau hauv alkaline nruab nrab, ntsev thiab molten ntsev.
Nws yog ib qho corrosion-resistant alloy nrog tus nqi loj tshaj plaws, feem ntau siv dav, thiab cov khoom zoo heev. Cov hlau no muaj kev tiv thaiv zoo heev hauv hydrofluoric acid thiab fluorine roj nruab nrab thiab kuj muaj kev tiv thaiv corrosion zoo heev hauv cov tshuaj kub concentrated alkali. Nyob rau tib lub sijhawm, nws tseem tiv taus corrosion los ntawm kev daws teeb meem nruab nrab, dej, dej hiav txwv, huab cua, organic compounds, thiab lwm yam. M400 yog ib qho ntawm ob peb cov ntaub ntawv tseem ceeb uas tiv taus hydrofluoric acid. Dej corrosion: M400 alloy tsis tsuas yog muaj kev tiv thaiv zoo heev hauv dej corrosion feem ntau tab sis kuj pitting corrosion thiab kev ntxhov siab corrosion tsis tshua pom. Feem ntau nyob ib ncig ntawm 600 degree, nyob rau hauv high-temperature chav, tus nqi corrosion yog tsawg dua 0.026mm / a. Ammonia: Vim lub siab nickel ntsiab lus ntawm Monel 400 alloy, nws yog resistant rau corrosion nyob rau hauv anhydrous ammonia thiab ammonia nyob rau hauv qab no 585 degree.
Monel 400 alloy kuj muaj cov khoom siv zoo, ntau yam kev siv kub los ntawm qhov kub thiab txias mus rau qhov kub thiab txias, kev ua haujlwm vuam zoo, thiab nruab nrab thiab siab zog.
Monel 400 feem ntau yog siv nyob rau hauv tshuaj thiab petrochemical thiab marine kev loj hlob teb. Nws tuaj yeem siv los tsim ntau yam khoom siv hluav taws xob sib pauv, boiler pub dej rhaub, roj av, thiab cov kav dej tshuaj, ntim, yees, tso tsheb hlau luam, li qub, twj, reactors, shafts, thiab lwm yam.
