He whānau koranu nikara a Hastelloy e mōhiotia ana mō tō rātou ātete pai ki te waikura me te kaha ki te pāmahana teitei. Ka rerekē pea te hanganga motuhake o ia koranu i roto i te whānau Hastelloy, engari he maha ngā wā kei roto ko te nikara, te chromium, te molybdenum, me ētahi atu huānga pērā i te rino, te cobalt, te tungsten, te parahi rānei. Ko ētahi o ngā koranu e whakamahia whānuitia ana i roto i te whānau Hastelloy ko te Hastelloy C-276, te Hastelloy C-22, me te Hastelloy X, he āhuatanga me ngā whakamahinga motuhake tō ia ko ia.
Ko te Hastelloy C276 he konukōre nui e tuku ana i te ātete tino pai ki te whānuitanga o ngā taiao waikura. He mea hanga motuhake kia tū atu ki ngā āhuatanga uaua pēnei i te waikawa waikura me te whakaiti, te wai moana, me ngā mea kei roto he chlorine. Ko te hanganga o te Hastelloy C276 he tata ki te 55% nikara, 16% chromium, 16% molybdenum, 4-7% rino, 3-5% tungsten, me ngā rahinga iti o ētahi atu huānga, pēnei i te cobalt, silicon, me te manganese. Mā tēnei huinga o ngā huānga ka hoatu ki te Hastelloy C276 tōna ātete tino pai ki te waikura, te poka, te pakaru o te waikura ahotea, me te waikura kapiti. Nā tōna ātete teitei ki ngā momo taiao matū kaha, he whānui te whakamahinga o te Hastelloy C276 i roto i ngā ahumahi pēnei i te tukatuka matū, te petrochemical, te hinu me te hau, te rongoā, me te whakahaere parahanga. Ka kitea te tono i roto i ngā taputapu pēnei i ngā tauhohenga, ngā whakawhiti wera, ngā takirere, ngā papu, me ngā paipa kei reira te ātete ki te waikura he mea nui.

Aroha mai mō te pōhēhētanga i roto i taku whakautu o mua. Ko te Hastelloy C22 tētahi atu konukōre nui e ahu mai ana i te nikara e whakamahia whānuitia ana i roto i ngā taiao waikura. E mōhiotia ana hoki ko te Konukōre C22, ko te UNS N06022 rānei. He ātete pai rawa atu te Hastelloy C22 ki ngā mea whakahāwea me ngā mea whakaiti, tae atu ki ngā kukū whānui o ngā katote konukōre. Kei roto tata ki te 56% te nikara, 22% te konukōre, 13% te moripirinemu, 3% te tungsten, me te iti o te rino, te konukōre, me ētahi atu huānga. He tino ātete tēnei konukōre ki te waikura, ā, he tino pai te ātete matū, he pai mō ngā tono maha i roto i ngā ahumahi pēnei i te tukatuka matū, te matū hinu, te rongoā, me te maimoatanga para. He maha ngā wā e whakamahia ana i roto i ngā taputapu pēnei i ngā tauhohenga, ngā whakawhiti wera, ngā oko pēhanga, me ngā pūnaha paipa e pā ana ki ngā matū kaha, ngā waikawa, me ngā konukōre. Ka taea e te Hastelloy C22 te tu atu ki ngā pāmahana teitei, ā, he pai te kaha ki te whakarewa, he mea whiriwhiri maha mō te whānuitanga o ngā taiao waikura. Ko tōna huinga ahurei o ngā koranu e whakarato ana i te ātete tino pai ki te waikura ōrite me te waikura ā-rohe, e waiho ana hei whiringa rongonui i roto i ngā tono ahumahi maha.

Ko te Hastelloy C276 me te koranu C-276 e pā ana ki te koranu kotahi e ahu mai ana i te nikara, e tohua ana ko UNS N10276. E mōhiotia ana tēnei koranu mō tōna ātete pai ki te waikura i roto i te whānuitanga o ngā taiao kino, tae atu ki ngā mea kei roto ngā waikawa whakahāwea me te whakaiti, ngā mea kei roto he kōhaita, me te wai moana. Ko ngā kupu "Hastelloy C276" me te "koranu C-276" e whakamahia ana hei tohu i tēnei koranu motuhake. Ko te waitohu "Hastelloy" he tohu hokohoko nā Haynes International, Inc., nāna i whakawhanake me te whakaputa i te koranu i te tuatahi. Ko te kupu whānui "koranu C-276" he huarahi noa ki te tohu i tēnei koranu i runga i tōna tohu UNS. Hei whakarāpopototanga, kāore he rerekētanga i waenga i te Hastelloy C276 me te koranu C-276; he koranu kotahi rāua, ā, e kiia ana mā te whakamahi i ngā tikanga whakaingoa rerekē.
He konukōrei nikara te Hastelloy C22 me te C-276, he rite tonu ngā hanganga.
Heoi anō, kei reira ētahi rerekētanga nui i waenganui i ngā mea e rua: Te Hanganga: Kei roto i te Hastelloy C22 te 56% o te nikara, te 22% o te konukōrema, te 13% o te moripātenema, te 3% o te tungsten, me te iti o te rino, te kopara, me ētahi atu huānga. I tētahi atu taha, kei roto i te Hastelloy C-276 te 57% o te nikara, te 16% o te moripātenema, te 16% o te konukōrema, te 3% o te tungsten, me te iti o te rino, te kopara, me ētahi atu huānga. Te Ātete ki te Waikura: E mōhiotia ana ngā koranu e rua mō tō rātou ātete ki te waikura.
Heoi, he pai ake te ātete whānui o te Hastelloy C-276 ki te waikura i te C22 i roto i ngā taiao tino kaha, inā koa ki ngā matū whakahāweawe pērā i te chlorine me ngā otinga hypochlorite. He pai ake te C-276 mō ngā tono kei reira te taiao he nui ake te waikura. Te Āhua Whakarewa: He ngāwari te whakarewa i te Hastelloy C22 me te C-276.
Heoi, he pai ake te kaha o te whakarewa o te C-276 nā te iti o te waro, e whakarato ana i te ātete pai ake ki te whakaaweawe me te maturuturunga o te carbide i te wā whakarewa. Te whānuitanga pāmahana: Ka taea e ngā koranu e rua te tu atu ki ngā pāmahana teitei, engari he whānui ake te whānuitanga pāmahana o te C-276. He pai te C22 mō ngā pāmahana whakahaere tae atu ki te 1250°C (2282°F), ko te C-276 ia ka taea te tu atu ki ngā pāmahana tae atu ki te 1040°C (1904°F). Ngā Whakamahinga: He mea whakamahi noa te Hastelloy C22 i roto i ngā ahumahi pēnei i te tukatuka matū, te rongoā, me te tukatuka para. He pai mō te whakahaere i ngā matū kaha, ngā waikawa, me ngā pūhaumāota. Ko te Hastelloy C-276, me tōna ātete waikura pai rawa atu, he maha ngā wā ka whiriwhiria mō ngā tono e hiahia ana ki te ātete pai ki ngā taiao waikura me te whakaiti, pēnei i te tukatuka matū, te whakahaere parahanga, me ngā ahumahi hinu me te hau.
Hei whakarāpopototanga, ahakoa he rauemi tino pai a Hastelloy C22 me C-276 mō ngā taiao waikura, he pai ake te ātete waikura a C-276 i ngā taiao tino pukuriri, ko C22 ia he pai ake mō ngā tono e nui ai te mahi whakarewa, te ātete rānei ki ētahi matū.Ko te kōwhiringa i waenga i ngā mea e rua ka whakawhirinaki ki ngā whakaritenga motuhake o te tono.
