Monel 400 ndi Monel 405 ndi ma aloyi a nickel-copper ogwirizana kwambiri omwe ali ndi mphamvu zotsutsana ndi dzimbiri. Komabe, palinso kusiyana pakati pawo:
1. Zolemba:
Monel 400 ili ndi pafupifupi 67% nickel ndi 30% yamkuwa, ndipo ili ndi zinthu zina zazing'ono monga chitsulo, manganese ndi silicon. Kumbali ina, Monel 405 ili ndi mawonekedwe osinthika pang'ono ndikuwonjezera pang'ono (0.5-1.5%) ya aluminiyamu. Kuwonjezera uku kumathandiza kupititsa patsogolo makina a alloy ndikuwonjezera mphamvu zake. , ndi zina.
2. Mphamvu ndi kuuma:
Chifukwa cha kuwonjezeredwa kwa aluminiyumu, Monel 405 imasonyeza mphamvu ndi kuuma kwambiri kuposa Monel 400. Izi zimapangitsa Monel 405 kukhala yabwino kwambiri kwa mapulogalamu omwe amafunikira mphamvu zowonjezereka komanso kuuma.
3. Weldability:
Poyerekeza ndi Monel 400, Monel 405 ikuwonetsa kuwotcherera bwino. Kuwonjezera zotayidwa kumathandiza kuchepetsa mapangidwe intergranular carbides pa kuwotcherera, kumawonjezera weldability wa aloyi, ndi kuchepetsa chiopsezo kuwotcherera ming'alu.
4. Kugwiritsa ntchito:
Chifukwa cha kukana bwino kwa dzimbiri, makamaka m'malo amadzi a m'nyanja, Monel 400 imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza panyanja, kukonza mankhwala, mafuta ndi gasi. Monel 405 imapereka mphamvu zowonjezera komanso kuwotcherera ndipo imagwiritsidwa ntchito kwambiri pazinthu monga mapampu, zomangira ndi zigawo za valve.
5. Perekani munthu wapadera:
Kukhala ndi udindo pakukonzekera ndi kugwirizanitsa kwa Fire drillkuonetsetsa kukhazikitsidwa bwino kwa kubowola.
Ponseponse, pomwe onse a Monel 400 ndi Monel 405 ali ndi kukana kwambiri kwa dzimbiri, Monel 405 imapereka mphamvu zowonjezera komanso kuwotcherera poyerekeza ndi Monel 400, ndikupangitsa kuti ikhale yabwinoko pazinthu zina.
