Tus qauv ntawm Monel 400 alloy phaj(UNS N04400, NCu30) yog ib lub zog muaj zog ib-theem cov khoom siv, uas yog cov khoom siv corrosion-resistant alloy nrog cov nqi loj tshaj plaws, kev siv dav tshaj plaws, thiab kev ua haujlwm zoo heev.Cov hlau no muaj kev tiv thaiv zoo heev hauv hydrofluoric acid thiab fluorine gas media, thiab tseem muaj kev tiv thaiv corrosion zoo heev rau kub concentrated alkaline tov.Nws kuj tseem tiv taus corrosion los ntawm cov kev daws teeb meem nruab nrab, dej, dej hiav txwv, huab cua, organic compounds, thiab lwm yam. Ib qho tseem ceeb ntawm cov hlau no yog tias nws feem ntau tsis tsim kev ntxhov siab corrosion thiab muaj kev ua haujlwm zoo.
Cov hlau no muaj kev tiv thaiv zoo heev hauv cov roj fluorine, hydrochloric acid, sulfuric acid, hydrofluoric acid, thiab lawv cov derivatives.Nyob rau tib lub sijhawm, nws muaj kev tiv thaiv corrosion zoo dua li tooj liab raws alloys hauv dej hiav txwv.
Acid nruab nrab:Monel 400yog corrosion-resistant nyob rau hauv sulfuric acid nrog ib tug concentration ntawm tsawg tshaj li 85%.Monel 400 yog ib qho ntawm ob peb cov ntaub ntawv tseem ceeb hauv cov tshuaj hydrofluoric acid.
Cov dej corrosion:Monel 400 alloyTsis tsuas yog muaj kev tiv thaiv zoo heev nyob rau hauv cov dej corrosion feem ntau, tab sis kuj tsis tshua muaj kev paub txog pitting corrosion, kev nyuaj siab corrosion, thiab lwm yam, nrog tus nqi corrosion tsawg dua 0.25mm / a
Kev kub siab corrosion: Qhov kub siab tshaj plaws rau kev ua haujlwm tas li ntawm Monel 400 hauv huab cua feem ntau yog nyob ib puag ncig 600 ℃.Nyob rau hauv high-kub chav, tus nqi corrosion yog tsawg dua 0.026mm / a
Ammonia: Vim yog cov ntsiab lus siab nickel ntawmMonel 400alloy, nws tuaj yeem tiv taus corrosion nyob rau hauv anhydrous ammonia thiab ammonification tej yam kev mob hauv qab 585 ℃.
