Ke kala aku nei au no ka huikau i kaʻu pane mua. ʻO Hastelloy C22 kekahi superalloy nickel-based i hoʻohana pinepine ʻia i nā wahi corrosive. Ua ʻike ʻia hoʻi ʻo ia ʻo Alloy C22 a i ʻole UNS N06022. Hāʻawi ʻo Hastelloy C22 i ke kū'ē maikaʻi loa i nā media oxidizing a me ka hōʻemi ʻana, me nā ʻano ākea o nā ion chloride. Loaʻa iā ia ma kahi o 56% nickel, 22% chromium, 13% molybdenum, 3% tungsten, a me nā liʻiliʻi o ka hao, cobalt, a me nā mea ʻē aʻe. He kūpaʻa loa kēia alloy i ka corrosion a he kūpaʻa kemika maikaʻi loa, e kūpono ai no nā noi like ʻole i nā ʻoihana e like me ka hana kemika, petrochemical, pharmaceutical, a me ka mālama ʻōpala. Hoʻohana pinepine ʻia ia i nā lako e like me nā reactors, nā mea hoʻololi wela, nā ipu kaomi, a me nā ʻōnaehana paiping e pili ana me nā kemika huhū, nā waikawa, a me nā chlorides. Hiki iā Hastelloy C22 ke kū i nā mahana kiʻekiʻe a he weldability maikaʻi, e lilo ia i koho versatile no nā ʻano wahi corrosive like ʻole. ʻO kona hui kūikawā o nā metala hoʻohuihui e hāʻawi i ke kūpaʻa maikaʻi loa i ka pala like a me ka pala kūloko, e lilo ia i koho kaulana i nā noi ʻoihana he nui.

ʻO Hastelloy C276 a me ke kinikini C-276 e pili ana i ka kinikini nickel like, i kapa ʻia ʻo UNS N10276. Ua ʻike ʻia kēia kinikini no kona kūpaʻa maikaʻi loa i ka palaho ma nā ʻano kaiapuni koʻikoʻi, me nā mea i loaʻa nā waikawa oxidizing a me ka hoʻemi ʻana, nā mea i loaʻa ka chloride, a me ka wai kai. Hoʻohana ʻia nā huaʻōlelo "Hastelloy C276" a me "konkini C-276" e hōʻike i kēia kinikini kikoʻī. ʻO ka hōʻailona "Hastelloy" he hōʻailona kālepa ia na Haynes International, Inc., nāna i hoʻomohala mua a hana i ka kinikini. ʻO ka huaʻōlelo maʻamau "konkini C-276" kahi ala maʻamau e kapa ai i kēia kinikini ma muli o kona hoʻolālā UNS. I ka hōʻuluʻulu manaʻo, ʻaʻohe ʻokoʻa ma waena o Hastelloy C276 a me ke kinikini C-276; he kinikini like lāua a ua kapa wale ʻia me ka hoʻohana ʻana i nā ʻano inoa like ʻole.
ʻO Hastelloy C22 lāua ʻo C-276 he mau superalloys i hoʻokumu ʻia i ka nickel me nā ʻano like.
Eia nō naʻe, aia kekahi mau ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua: Ka Hui ʻana: Loaʻa iā Hastelloy C22 ma kahi o 56% nickel, 22% chromium, 13% molybdenum, 3% tungsten, a me nā mea liʻiliʻi o ka hao, cobalt, a me nā mea ʻē aʻe. Ma ka ʻaoʻao ʻē aʻe, loaʻa iā Hastelloy C-276 ma kahi o 57% nickel, 16% molybdenum, 16% chromium, 3% tungsten, a me nā mea liʻiliʻi o ka hao, cobalt, a me nā mea ʻē aʻe. Ke kū'ē ʻana i ka pala: Ua ʻike ʻia nā mea hoʻohui ʻelua no ko lākou kūpaʻa ʻana i ka pala.
Eia nō naʻe, hāʻawi ʻo Hastelloy C-276 i ke kūpaʻa ʻana i ka pala ma mua o C22 i nā wahi hoʻonāukiuki loa, ʻoi aku hoʻi i nā mea hoʻomake oxidizing e like me ka chlorine a me nā hopena hypochlorite. Makemake pinepine ʻia ʻo C-276 no nā noi kahi i ʻoi aku ka pala o ke kaiapuni. Weldability: He maʻalahi ka weld ʻana iā Hastelloy C22 a me C-276.
Eia nō naʻe, ʻoi aku ka maikaʻi o ka weldability o C-276 ma muli o kona emi ʻana o ke kalapona, kahi e hāʻawi ai i ka pale ʻana i ka sensitization a me ka carbide precipitation i ka wā o ka welding. Pae mahana: Hiki i nā alloys ʻelua ke lawelawe i nā mahana kiʻekiʻe, akā ʻoi aku ka laulā o ka mahana o C-276. Kūpono ʻo C22 no nā mahana hana a hiki i kahi o 1250°C (2282°F), ʻoiai hiki iā C-276 ke lawelawe i nā mahana a hiki i kahi o 1040°C (1904°F). Nā noi: Hoʻohana pinepine ʻia ʻo Hastelloy C22 i nā ʻoihana e like me ka hana kemika, nā lāʻau lapaʻau, a me ka mālama ʻōpala. He kūpono ia no ka lawelawe ʻana i nā kemika huhū like ʻole, nā waikawa, a me nā chlorides. ʻO Hastelloy C-276, me kona kūpaʻa ʻana i ka corrosion kiʻekiʻe, ua koho pinepine ʻia no nā noi e pono ai ke kūpaʻa maikaʻi loa i nā wahi oxidizing a me ka hōʻemi ʻana, e like me ka hana kemika, ka kaohi haumia, a me nā ʻoihana aila a me ke kinoea.
I ka hōʻuluʻulu manaʻo, ʻoiai ʻo Hastelloy C22 lāua ʻo C-276 he mau mea maikaʻi loa no nā kaiapuni ʻino, hāʻawi pinepine ʻo C-276 i ke kūpaʻa ʻoi aku ka maikaʻi ma mua o ka pala ʻana i nā kaiapuni huhū loa, ʻoiai ʻoi aku ka maikaʻi o C22 no nā noi kahi e koʻikoʻi ai ka hoʻoheheʻe ʻana a i ʻole ke kūʻē ʻana i kekahi mau kemika.ʻO ke koho ma waena o nā mea ʻelua e pili ana i nā koi kikoʻī o ka noi.
