I-Monel K400 ne-K500 womabili angamalungu omndeni owaziwayo we-Monel alloy, kodwa anezici ezihlukene eziwahlukanisayo, okwenza ngayinye ifanele ukusetshenziswa okuhlukile. Ukuqonda lo mehluko kubalulekile konjiniyela, abakhiqizi, kanye nabathandi bezinto ezibonakalayo abafuna ukwenza izinqumo zokukhetha izinto ezinolwazi.

Umehluko obaluleke kakhulu usekuhlanganiseni kwawo kwamakhemikhali.I-MonelI-K400 yakhiwe ngokuyinhloko nge-nickel (cishe ama-63%) kanye nethusi (28%), kanye nenani elincane lensimbi ne-manganese. Lokhu kwakheka kwe-alloy okulula kodwa okusebenzayo kunomthelela ekuphikeleni kwayo okuhle kakhulu kokugqwala kanye nezakhiwo ezinhle zemishini ekamelweni lokushisa. Ngokuphambene, iMonel K500 yakhela phezu kwesisekelo se-K400 ngokwengeza i-aluminium ne-titanium. Lezi zakhi ezengeziwe zenza i-K500 ikwazi ukubhekana nenqubo yokuqina kwemvula, ethuthukisa kakhulu amandla ayo nobulukhuni uma kuqhathaniswa ne-K400.

Lokhu kungafani kokuqanjwa kuthinta ngqo izici zabo zemishini. I-Monel K400 inikeza i-ductility enhle nokwakheka, okwenza kube lula ukwenza izimo ezihlukahlukene. Inamandla okunyakazisa aphansi uma kuqhathaniswa, alungele izinhlelo zokusebenza lapho ukuguquguquka nokulula komshini kuyizinto eziza kuqala, njengasekukhiqizweni kwamasistimu amapayipi olwandle kanye nezingxenye zenhloso ezijwayelekile ezimelana nokugqwala. I-Monel K500, ngemva kokuqina kwezulu, ibonisa amandla aphakeme kakhulu okunyakazisa kanye nesivuno. Ingamelana nokucindezeleka okukhulu komshini, iyenze ifaneleke izinhlelo zokusebenza ezidinga izingxenye eziqinile, njengezigxobo zephampu, iziqu zamavalvu, nezixhumi emishinini esindayo nemikhumbi yasolwandle.

Ukumelana nokugqwala kungenye indawo lapho ama-alloys amabili ekhombisa umehluko. Kokubili uMonel K400 kanyeK500inikeza ukumelana okuhle kakhulu nenhlobonhlobo yemithombo yezindaba ebolayo, ehlanganisa amanzi olwandle, ama-asidi athambile, nama-alkali. Kodwa-ke, ngenxa yamandla ayo aphezulu kanye nokwakheka kongqimba oluqinile lwe-oxide evikelayo ngesikhathi sokuqina kwezulu, i-Monel K500 ivame ukubonisa ukumelana okuthuthukisiwe ekuqhekekeni kokugqwala kwengcindezi, ikakhulukazi ezindaweni ezinokuqukethwe okuphezulu kwe-chloride. Lokhu kwenza i-K500 ibe inketho ekhethwayo yezingxenye ezingavezwa nje kuphela ezintweni ezibolayo kodwa futhi ezidinga ukubekezelela ukucindezeleka komshini ngesikhathi esisodwa.

Mayelana nezicelo, i-Monel K400 ivamise ukusetshenziswa embonini yasolwandle ezingxenyeni ezinjengama-condensers, izishintshisi zokushisa, namapayipi amanzi olwandle, lapho ukumelana nokugqwala kwawo kubaluleka. Iphinde isetshenziswe embonini yamakhemikhali ekuphatheni amakhemikhali angenalo ulaka. I-Monel K500, ngakolunye uhlangothi, isetshenziswa ezicelweni ezidingeka kakhulu. Emkhakheni kawoyela negesi, isetshenziselwa amathuluzi e-downhole kanye nemishini ye-subsea, lapho amandla aphezulu kanye nokumelana nokugqwala kubalulekile. Embonini ye-aerospace, izingxenye ze-K500 zingatholakala ezingxenyeni ezidinga kokubili amandla nokumelana nokugqwala kwemvelo.
