ʻO Inconel 800 a me Incoloy 800H nā nickel-iron-chromium alloys, akā aia kekahi mau ʻokoʻa i ka haku mele a me nā waiwai.
ʻO Incoloy 800 kahi nickel-iron-chromium alloy i hoʻolālā ʻia no nā noi wela kiʻekiʻe. Aia ia i ka Incoloy series of superalloys a loaʻa iā ia ke kūpaʻa corrosion maikaʻi loa i nā wahi like ʻole.
Huina:
Nikela: 30-35%
Chromium: 19-23%
Hao: 39.5% ka liʻiliʻi
ʻO nā mea liʻiliʻi o ka aluminika, ka titanium, a me ke kalapona
Nā waiwai:
Kūleʻa wela kiʻekiʻe: Hiki i ka Incoloy 800 ke pale i nā mahana kiʻekiʻe a hiki i 1100 ° C (2000 ° F), kūpono ia no nā noi i nā ʻoihana hoʻomehana wela.
ʻO ke kūpaʻa ʻino: Hāʻawi ia i ke kūpaʻa maikaʻi loa i ka oxidation, carburization, a me ka nitridation i nā kaiapuni me ke kiʻekiʻe kiʻekiʻe a me nā lewa sulfur.
Ka ikaika a me ka ductility: Loaʻa iā ia nā waiwai mechanical maikaʻi, me ka ikaika tensile kiʻekiʻe a me ka paʻakikī.
Paʻa wela: Mālama ʻo Incoloy 800 i kāna mau waiwai ma lalo o ka hoʻomehana cyclic a me nā kūlana hoʻomaha.
Weldability: Hiki ke maʻalahi i ka welded me ka hoʻohana ʻana i nā ʻano kuʻi maʻamau.
Nā noi: Hoʻohana pinepine ʻia ʻo Incoloy 800 i nā ʻoihana like ʻole, me:
Hoʻohana kemika: Hoʻohana ʻia ia i ka hana ʻana i nā mea hana e like me nā mea hoʻololi wela, nā moku hopena, a me nā ʻōnaehana paipu e mālama i nā kemika corrosive.
Hoʻoulu mana: Hoʻohana ʻia ʻo Incoloy 800 i nā mea kanu mana no nā noi wela kiʻekiʻe, e like me nā ʻāpana boiler a me nā mea hana mahu hoʻōla wela.
ʻO ka hana Petrochemical: He kūpono ia no nā mea hana i hōʻike ʻia i nā wela kiʻekiʻe a me nā wahi corrosive i loko o nā refineries petrochemical.
ʻO nā kapuahi ʻenehana: Hoʻohana ʻia ʻo Incoloy 800 e like me nā mea hoʻomehana, nā paipu kukui, a me nā mea ʻē aʻe i loko o nā umu wela wela.
Aerospace a me nā ʻoihana automotive: Hoʻohana ʻia ia i nā noi e like me nā pahu puhi turbine gas a me nā ʻāpana afterburner.
Ma keʻano holoʻokoʻa, ʻo Incoloy 800 kahi mea hoʻohui like me ka maikaʻi kiʻekiʻe-kiʻekiʻe a me ka corrosion-kūpono waiwai, e kūpono ai no nā noi ʻoihana koi.
ʻO Incoloy 800H kahi mana i hoʻololi ʻia o Incoloy 800, i hoʻomohala kūikawā ʻia e hāʻawi i ke kūpaʻa ʻoi aku ka nui a me ka ikaika o ka wela kiʻekiʻe. ʻO ka "H" ma Incoloy 800H ke kū nei no ka "wela kiʻekiʻe."
Hoʻohui: ʻO ka hui ʻana o Incoloy 800H ua like ia me Incoloy 800, me kekahi mau hoʻololi e hoʻonui ai i kona hiki ke wela kiʻekiʻe. ʻO nā mea nui o ka alloying:
Nikela: 30-35%
Chromium: 19-23%
Hao: 39.5% ka liʻiliʻi
ʻO nā mea liʻiliʻi o ka aluminika, ka titanium, a me ke kalapona
Hoʻopaʻa ʻia nā mea alumini a me ka titanium ma Incoloy 800H e hāpai i ka hoʻokumu ʻana i kahi pae paʻa i kapa ʻia ʻo carbide i ka wā lōʻihi o ka hoʻolaha ʻana i nā mahana kiʻekiʻe. ʻO kēia māhele carbide e kōkua i ka hoʻomaikaʻi ʻana i ka pale ʻana i nā kolo.
Nā waiwai:
Hoʻonui i ka ikaika wela kiʻekiʻe: ʻO Incoloy 800H ka ikaika mechanical kiʻekiʻe ma mua o Incoloy 800 ma nā mahana kiʻekiʻe. Mālama ʻo ia i kona ikaika a me kona kūpaʻa ʻana ma hope o ka loaʻa ʻana o ka lōʻihi i nā wela kiʻekiʻe.
Hoʻomaikaʻi ʻia ke kū ʻana o nā kolo: ʻO ke kolo ka ʻano o kahi mea e hoʻoheheʻe mālie ma lalo o ke koʻikoʻi mau i nā wela kiʻekiʻe. Hōʻike ʻo Incoloy 800H i ka hoʻomaikaʻi ʻana i ke kūpaʻa ʻana i ke kolo ʻana ma mua o Incoloy 800, e kūpono ana i nā noi e koi ana i ka lōʻihi o ka ʻike ʻana i nā mahana kiʻekiʻe.
ʻO ke kūpaʻa ʻino maikaʻi loa: E like me Incoloy 800, hāʻawi ʻo Incoloy 800H i ke kūpaʻa maikaʻi loa i ka oxidation, carburization, a me ka nitridation i loko o nā wahi corrosive like ʻole.
ʻO ka weldability maikaʻi: Hiki ke hoʻopili maʻalahi ʻia ʻo Incoloy 800H me ka hoʻohana ʻana i nā ʻenehana kuʻi maʻamau.
Nā noi: Hoʻohana nui ʻia ʻo Incoloy 800H i nā noi kahi e pono ai ke kūʻē ʻana i nā wahi wela a me ka corrosion, e like me:
ʻO ka hana kemika a me ka petrochemical: He kūpono ia no ka hana ʻana i nā mea hana e lawelawe ana i nā kemika koʻikoʻi, nā ea i loko o ka sulfur, a me nā kaiapuni corrosive kiʻekiʻe.
Nā mea hoʻololi wela: Hoʻohana pinepine ʻia ʻo Incoloy 800H no nā paipu a me nā ʻāpana i nā mea hoʻololi wela ma muli o kona ikaika kiʻekiʻe a me ka pale ʻana i ka corrosion.
Ka hana mana: Loaʻa iā ia nā noi i nā mea kanu mana no nā ʻāpana i hui pū me nā kinoea wela, ka mahu, a me nā wahi wela wela.
Nā kapuahi ʻenehana: Hoʻohana ʻia ʻo Incoloy 800H i nā paipu kukui, muffles, a me nā ʻāpana umu ʻē aʻe i ʻike ʻia i nā wela kiʻekiʻe.
ʻO nā turbines kinoea: Ua hoʻohana ʻia ia i nā ʻāpana o nā turbines kinoea e pono ai ke kūpaʻa maikaʻi loa a me ka ikaika wela kiʻekiʻe.
Ma keʻano holoʻokoʻa, ʻo Incoloy 800H kahi alloy holomua e hāʻawi i ka ikaika kiʻekiʻe-kiʻekiʻe a hoʻomaikaʻi i ke kūpaʻa creep i hoʻohālikelike ʻia me Incoloy 800, e kūpono ana i ke koi ʻana i nā noi ʻoihana e hana ana i nā mahana kiʻekiʻe.
ʻO Incoloy 800 a me Incoloy 800H ʻelua mau ʻano like ʻole o ka nickel-iron-chromium alloy, me nā ʻokoʻa liʻiliʻi i kā lākou haku mele a me nā waiwai. Eia nā ʻokoʻa nui ma waena o Incoloy 800 a me Incoloy 800H:
Huina Kemika:
Incoloy 800: He 32% nickel kona, 20% chromium, 46% hao, me nā mea liʻiliʻi e like me ke keleawe, titanium, a me ka alumini.
Incoloy 800H: He mana hoʻololi ia o Incoloy 800, me kahi haku mele ʻokoʻa. Loaʻa iā ia ma kahi o 32% nickel, 21% chromium, 46% hao, me ka hoʻonui kalapona (0.05-0.10%) a me ka alumini (0.30-1.20%) mau mea.
Nā waiwai:
Ka ikaika kiʻekiʻe: ʻO Incoloy 800 a me Incoloy 800H ke hāʻawi aku i ka ikaika maikaʻi a me nā waiwai mechanical i nā mahana kiʻekiʻe. Eia naʻe,ʻo Incoloy 800H ka ikaika kiʻekiʻe kiʻekiʻe aʻoi aku ka maikaʻi o ke kū'ēʻana o ka creep ma mua o Incoloy 800. ʻO kēia ma muli o ka hoʻonuiʻia o ke kalapona a me ka alumini i loko o Incoloy 800H, e hoʻoikaika ana i ke kūkuluʻiaʻana o kahi carbide paʻa paʻa, e hoʻonui ana i kona kū'ēʻana i ka deformation creep.
Kū'ē Kū'ē:ʻO Incoloy 800 a me Incoloy 800H hōʻike i nā kūlana likeʻole o ke kū'ēʻana i ka corrosion, e hāʻawi ana i ke kū'ē maikaʻi loa i ka oxidation, carburization, a me ka nitridation i nā kaiapuni corrosive.
Weldability: Hiki ke wiliwili ʻia nā ʻāpana ʻelua me ka hoʻohana ʻana i nā ʻenehana wili maʻamau.
Nā noi: Loaʻa i ka Incoloy 800 a me Incoloy 800H kahi ākea o nā noi ʻoihana kahi e koi ʻia ai ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion. Aia kekahi mau noi maʻamau:
ʻO nā mea hoʻololi wela a me nā paipu kaʻina hana i nā ʻoihana kemika a me ka petrochemical.
ʻO nā ʻāpana kapuahi e like me nā paipu kukui, muffles, a me nā pā.
Nā mea kanu hana mana, me nā mea i loko o nā paila mahu a me nā turbines kinoea.
ʻO nā umu ahi a me nā mea puhi ahi.
Kākoʻo ʻo Catalyst i nā grids a me nā mea paʻa i ka hana ʻana i ka aila a me ke kinoea.
ʻOiai kūpono ʻo Incoloy 800 no nā noi wela kiʻekiʻe, ua hoʻolālā ʻia ʻo Incoloy 800H no nā kaiapuni e koi ana i ke kūpaʻa kiʻekiʻe a me ka ikaika wela kiʻekiʻe. ʻO ka koho ma waena o lākou e pili ana i ka noi kikoʻī a me nā waiwai i makemake ʻia.
