ʻO Nickel Alloy Monel K-500, ka mea hoʻopaʻa paʻa makahiki, i loaʻa i ka alumini a me ka titanium, e hui pū i nā hiʻohiʻona pale corrosion maikaʻi loa o Monel 400 me nā pono hoʻohui o ka hoʻonui ʻana i ka ikaika, paʻakikī, a me ka mālama ʻana i kona ikaika a hiki i 600 ° C.
ʻO ke kūpaʻa ʻino ʻana o Monel K-500 he ʻano like ia me ka Monel 400 koe wale nō, ma ke ʻano paʻakikī o ka makahiki, ʻoi aku ka maʻalahi o Monel K-500 i ke koʻikoʻi-corrosion māwae i kekahi mau kaiapuni.
ʻO kekahi o nā noi maʻamau o ka nickel alloy K-500 no nā kumu pahū, nā impellers, nā lāʻau lapaʻau a me nā ʻōpala, nā kola luawai ʻaila, a me nā mea hana hoʻopau ʻē aʻe, nā mea uila, nā pūnāwai a me nā kaʻa valve. Hoʻohana nui ʻia kēia alloy i nā noi ʻoihana moana a me ka aila a me ke kinoea. ʻO ka ʻokoʻa ʻo Monel 400 ʻoi aku ka maʻalahi, e ʻike i nā hoʻohana he nui i loko o nā hale, nā ʻauwai, a me nā ʻāpana hoʻolālā ma kahi o nā hale hoʻonaʻauao, nā paipu o ka boiler feed water heaters, nā noi wai kai (sheathing, nā mea ʻē aʻe), HF alkylation process, hana a me ka lawelawe ʻana o HF acid, a me ka hoʻomaʻemaʻe ʻana i ka uranium, distillation, condensation units, a me nā paipu condenser ma luna o nā hale hoʻoheheʻe a me nā ʻoihana petrochemical, a me nā mea ʻē aʻe he nui.
