Monel Alloy 400
ʻO ka wehewehe pōkole:
Monel 400he anickel-copper alloy(e pili ana i 67% Ni - 23% Cu) ka mea kū'ē i ka wai kai a me ka mahu ma nā wela kiʻekiʻe e like me ka paʻakai a me ka wai hoʻonā.Huina 400he mea hoʻoheheʻe paʻa paʻa i hiki ke hoʻopaʻakikī wale ʻia e ka hana anu. Hōʻike kēia nickel alloy i nā hiʻohiʻona e like me ke kūpaʻa corrosion maikaʻi, ka weldability maikaʻi a me ka ikaika kiʻekiʻe. ʻO ka haʻahaʻa haʻahaʻa i loko o ke kahe wikiwiki ʻana a i ʻole ka wai kai i hui pū ʻia me ke kūpaʻa maikaʻi loa i ka pohā ʻana i ke koʻikoʻi-corrosion i loko o ka hapa nui o nā wai maʻemaʻe, a ʻo kona kūpaʻa ʻana i nā ʻano ʻino like ʻole i alakaʻi ʻia i kona hoʻohana ākea i nā noi kai a me nā mea hoʻonā chloride non-oxidizing ʻē aʻe. ʻO kēia nickel alloy ka mea kūʻokoʻa i ka hydrochloric a me ka hydrofluoric acid i ka wā e de-aerated. E like me ka mea i manaʻo ʻia mai kona ʻike keleawe kiʻekiʻe, ua hoʻouka koke ʻia ka alloy 400 e ka nitric acid a me nā ʻōnaehana amonia.
ʻO Monel 400 ka waiwai mechanical nui ma nā mahana subzero, hiki ke hoʻohanaʻia i nā mahana a hiki i ka 1000 ° F, aʻo kona helu hoʻoheheʻe he 2370-2460 ° F. Eia naʻe, he haʻahaʻa ka ikaika o ka alloy 400 i loko o ke kūlana annealed no laila, nāʻano wela. hiki ke hoʻohana ʻia e hoʻonui i ka ikaika.

He aha nā hiʻohiʻona o Monel 400?
- Kūleʻa i ka wai kai a me ka mahu i nā wela kiʻekiʻe
- Kūleʻa maikaʻi loa i ka wai paʻakai a i ʻole ka wai kai
- Kūleʻa maikaʻi i ke koʻikoʻi i ka pohā ʻana i ka wai maʻemaʻe
- Kūʻē kūʻē i ka waika hydrochloric a me ka hydrofluoric ke hoʻopau ʻia lākou
- Hāʻawi i kahi kū'ē i ka waika hydrochloric a me ka sulfuric i nā mahana haʻahaʻa a me nā ʻike, akā kakaikahi ka mea i koho ʻia no kēia mau ʻakika.

Monel 400 kū'ē i ka ʻino
Huina 400ʻaneʻane pale ʻole i ka chloride ion stress corrosion ma nā kaiapuni maʻamau. ʻO ka maʻamau, ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion i ka hōʻemi ʻana i nā kaiapuni, akā ʻilihune i nā kūlana oxidizing. ʻAʻole pono ia i ka oxidizing acids, e like me ka nitric acid a me ka nitrous. Eia nō naʻe, kūpaʻa ia i ka hapa nui o nā alkalis, nā paʻakai, nā wai, nā huahana meaʻai, nā mea kūlohelohe a me nā kūlana o ka lewa i nā mahana maʻamau a kiʻekiʻe.
Hoʻouka ʻia kēia huila nickel i nā kinoea lawe sulfur ma luna o 700° F a hoʻouka ʻia ka sulfur hoʻoheheʻe ʻia i ka alloy ma nā mahana ma kahi o 500° F.
Hāʻawi ʻo Monel 400 e pili ana i ke kūpaʻa corrosion e like me ka nickel akā me ke kiʻekiʻe kiʻekiʻe o ka hana a me nā mahana a me ke kumu kūʻai haʻahaʻa ma muli o kona hiki ke hana ʻia.
Ma nā polokalamu hea i hoʻohana ʻia ai ʻo Monel 400?
