Monel 400 alloy (UNS N04400 zoo heev corrosion kuj thiab txhua yam khoom
Monel 400, tseem hu ua UNS N04400 los yog German qib 2.4360, yog ib qho tshwj xeeb alloy dav siv nyob rau hauv ntau lub teb vim nws zoo heev corrosion kuj thiab txhua yam khoom. Lub alloy cov chemistry tau ua tib zoo tsim kom tau raws li qhov yuav tsum tau ua hauv ntau qhov chaw ua haujlwm.
Cov ntsiab lus tshuaj lom neeg ntawm Monel 400 yog tswj hwm los ua kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm nws qhov kev ua tau zoo. Tshwj xeeb, nws tsis muaj ntau tshaj 0.3% carbon, tsis ntau tshaj 0.5% silicon, thiab tsis pub ntau tshaj 2% manganese. Tsis tas li ntawd, txawm hais tias cov ntsiab lus phosphorus thiab sulfur tsis tau teev meej meej, cov ntsiab lus sulfur yog nruj me ntsis txwv tsis pub tsawg dua 0.024%. Cov hlau no tsis muaj chromium, tab sis nws cov ntsiab lus nickel yog tsawg kawg yog 63%, muab nws zoo heev corrosion kuj. Tib lub sijhawm, cov ntsiab lus tooj liab ntawm Monel 400 yog nyob nruab nrab ntawm 28.0-34.0%, uas ntxiv dag zog rau nws cov corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig. Cov ntsiab lus ntawm txhuas, titanium thiab hlau tsis tshaj 2.5%, kom ntseeg tau tias cov khoom siv ntawm cov hlau.
Cov khoom siv kho tshuab ntawm Monel 400 kuj zoo heev. Nws lub zog tensile yog tsawg kawg yog 450Mpa, yield zog tsawg kawg yog 170Mpa, thiab elongation yog tsawg kawg yog 30%. Cov cuab yeej zoo heev no ua rau Monel 400 siv dav hauv ntau lub teb.
Nyob rau hauv marine engineering, Monel 400 feem ntau yog siv los tsim marine heat exchangers, desalination khoom, ntsev ntau lawm khoom, thiab lwm yam vim nws muaj peev xwm tiv thaiv corrosion los ntawm seawater. Tsis tas li ntawd, hauv kev lag luam tshuaj, Monel 400 kuj tseem siv los tsim cov khoom siv marine thiab tshuaj ua haujlwm, kiv cua thiab cov twj tso kua mis, thiab lwm yam. raws li cov roj av thiab dej tank.
Zuag qhia tag nrho, Monel 400 yog cov khoom siv ua haujlwm siab uas nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov cuab yeej zoo heev tso cai rau nws ua tau zoo hauv ntau qhov chaw hnyav. Txawm hais tias nyob rau hauv marine engineering lossis tshuaj lom neeg kev lag luam, Monel 400 plays lub luag haujlwm tseem ceeb, muab kev tiv thaiv thiab kev txhawb nqa rau ntau yam khoom siv thiab cov khoom siv.
