Paʻa ʻino:
- Hōʻike ʻo Monel K500 i ke kūʻē maikaʻi ʻana i nā wahi ʻino like ʻole, me ka wai kai, brine, acids, alkalis, a me nā wahi kinoea ʻawaʻawa i loaʻa ka hydrogen sulfide (H2S).
- Paʻa loa ia i ka lua, ka ʻinoʻino a me ke koʻikoʻi ʻino (SCC).
- Hiki ke hoʻohana ʻia ka alloy i nā kūlana hoʻemi a me ka oxidizing.
Nā noi:
- ʻO nā ʻāpana moana, e like me nā ʻōhua propeller, nā ʻaupaʻa, nā valve, a me nā mea paʻa.
- ʻO nā lako ʻoihana ʻaila a me nā kinoea, me nā pumps, valves, a me nā mea hoʻopaʻa ikaika kiʻekiʻe.
- ʻO nā pūnāwai a me nā bellows i loko o ke kaomi kiʻekiʻe a me ka wela kiʻekiʻe.
- Nā mea uila a me nā mea uila.
- Aerospace a me nā noi pale.
He mau kuhikuhi maʻamau kēia mau kikoʻī, a ʻokoʻa paha nā waiwai kikoʻī ma muli o ke ʻano huahana a me ka mālama wela. Manaʻo mau ʻia e nīnau i ka mea hana a mea hoʻolako paha no ka ʻike kikoʻī kikoʻī e pili ana iā Monel K500.
ʻO Monel 400 lāua ʻo Monel K-500 nā ʻāpana ʻelua i loko o ka moʻo Monel a loaʻa i nā haku mele like ʻole, ʻo ia ka nickel a me ke keleawe. Eia nō naʻe, aia kekahi mau ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua e hoʻokaʻawale i kā lākou mau waiwai a me nā noi.
Ka Hoʻohui Kemika: ʻO ka Monel 400 he 67% nickel a me 23% keleawe, me ka liʻiliʻi o ka hao, manganese, a me nā mea ʻē aʻe. Ma ka ʻaoʻao ʻē aʻe, ʻo Monel K-500 kahi haku o kahi 65% nickel, 30% keleawe, 2.7% aluminika, a me 2.3% titanium, me ka nui o ka hao, manganese, a me ke silika. ʻO ka hoʻohui ʻana o ka alumini a me ka titanium i Monel K-500 e hāʻawi iā ia i ka ikaika a me ka paʻakikī i hoʻohālikelike ʻia me Monel 400.
Ka ikaika a me ka paʻakikī: Ua ʻike ʻia ʻo Monel K-500 no kona ikaika kiʻekiʻe a paʻakikī, hiki ke loaʻa ma o ka paʻakikī paʻakikī. ʻO ka ʻokoʻa, ʻoi aku ka palupalu o Monel 400 a he haʻahaʻa haʻahaʻa a me ka ikaika tensile.
Kū'ē Kū'ē: Ke hōʻike nei ʻo Monel 400 a me Monel K-500 i ke kūpaʻa ʻino maikaʻi loa ma nā wahi like ʻole, me ka wai kai, nā waikawa, nā alkalis, a me nā ʻano mea ʻino ʻē aʻe.
Hoʻohana: Hoʻohana pinepine ʻia ʻo Monel 400 i nā noi e like me ka ʻenekinia moana, ka hana kemika, a me nā mea hoʻololi wela, ma muli o kona kūpaʻa maikaʻi ʻana a me ka conductivity thermal kiʻekiʻe. ʻO Monel K-500, me kona ikaika a me ka paʻakikī, loaʻa nā noi i nā ʻāpana pump a me nā valve, nā mea hoʻopaʻa, nā pūnāwai, a me nā ʻāpana ʻē aʻe e koi ana i ka ikaika kiʻekiʻe a me ka pale ʻana i ka corrosion i nā wahi paʻakikī.
Ma ke ʻano holoʻokoʻa, ʻo ka koho ma waena o Monel 400 a me Monel K-500 e pili ana i nā koi kikoʻī no ka ikaika, paʻakikī, a me ka pale ʻana i ka corrosion i kahi noi i hāʻawi ʻia.
