Hastelloy ndi banja la ma alloy okhala ndi nickel omwe amadziwika kuti ndi olimbana ndi dzimbiri komanso amphamvu kwambiri pa kutentha. Kapangidwe kake ka alloy iliyonse m'banja la Hastelloy kamasiyana, koma nthawi zambiri amakhala ndi kuphatikiza kwa nickel, chromium, molybdenum, ndipo nthawi zina zinthu zina monga chitsulo, cobalt, tungsten, kapena mkuwa. Ma alloy ena omwe amagwiritsidwa ntchito kwambiri m'banja la Hastelloy ndi Hastelloy C-276, Hastelloy C-22, ndi Hastelloy X, iliyonse ili ndi mawonekedwe ake apadera komanso ntchito zake.
Hastelloy C276 ndi nickel-molybdenum-chromium superalloy yomwe imapereka kukana bwino kwambiri kumadera osiyanasiyana owononga. Yapangidwa mwapadera kuti ipirire mikhalidwe yovuta monga okosijeni ndi kuchepetsa asidi, madzi a m'nyanja, ndi zinthu zokhala ndi chlorine. Kapangidwe ka Hastelloy C276 nthawi zambiri kamakhala ndi pafupifupi 55% nickel, 16% chromium, 16% molybdenum, 4-7% chitsulo, 3-5% tungsten, ndi zinthu zina zochepa, monga cobalt, silicon, ndi manganese. Kuphatikiza kwa zinthu kumeneku kumapatsa Hastelloy C276 kukana kwake kwapadera ku dzimbiri, maenje, kusweka kwa dzimbiri, ndi dzimbiri la m'ming'alu. Chifukwa cha kukana kwake kwakukulu kumadera osiyanasiyana owopsa a mankhwala, Hastelloy C276 imagwiritsidwa ntchito kwambiri m'mafakitale monga kukonza mankhwala, petrochemical, mafuta ndi gasi, mankhwala, ndi kulamulira kuipitsa. Imagwiritsidwa ntchito m'zida monga ma reactor, osinthira kutentha, ma valve, mapampu, ndi mapaipi komwe kukana dzimbiri ndikofunikira.

Pepani chifukwa cha chisokonezo chomwe ndapeza mu yankho langa lapitalo. Hastelloy C22 ndi superalloy ina yochokera ku nickel yomwe imagwiritsidwa ntchito kwambiri m'malo owononga. Imadziwikanso kuti Alloy C22 kapena UNS N06022. Hastelloy C22 imapereka kukana kwakukulu kwa okosijeni ndi kuchepetsa zinthu, kuphatikizapo kuchuluka kwa ma chloride ions osiyanasiyana. Ili ndi pafupifupi 56% nickel, 22% chromium, 13% molybdenum, 3% tungsten, ndi chitsulo chochepa, cobalt, ndi zinthu zina. Alloy iyi imalimbana kwambiri ndi dzimbiri ndipo imalimbana bwino ndi mankhwala, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana monga kukonza mankhwala, petrochemical, mankhwala, ndi zinyalala. Nthawi zambiri imagwiritsidwa ntchito muzipangizo monga ma reactor, heat exchangers, pressure vessels, ndi mapaipi omwe amakumana ndi mankhwala amphamvu, ma acid, ndi ma chloride. Hastelloy C22 imatha kupirira kutentha kwambiri ndipo imatha kusunthika bwino, zomwe zimapangitsa kuti ikhale chisankho chosiyanasiyana m'malo osiyanasiyana owononga. Kuphatikiza kwake kwapadera kwa alloys kumapereka kukana kwabwino kwambiri ku dzimbiri lofanana komanso lapafupi, zomwe zimapangitsa kuti ikhale chisankho chodziwika bwino m'mafakitale ambiri.

Hastelloy C276 ndi aloyi C-276 zimatchula aloyi yofanana ndi nickel, yomwe imatchedwa UNS N10276. Aloyi imadziwika chifukwa cha kukana kwake dzimbiri m'malo osiyanasiyana ovuta, kuphatikizapo omwe ali ndi ma acid owonjezera ndi kuchepetsa, zinthu zokhala ndi chloride, ndi madzi a m'nyanja. Mawu akuti "Hastelloy C276" ndi "alloy C-276" amagwiritsidwa ntchito mosiyanasiyana kutanthauza aloyi yeniyeniyi. Mtundu wa "Hastelloy" ndi chizindikiro cha Haynes International, Inc., chomwe poyamba chinapanga ndikupanga aloyi. Mawu wamba akuti "alloy C-276" ndi njira yodziwika bwino yotchulira aloyi iyi kutengera dzina lake la UNS. Mwachidule, palibe kusiyana pakati pa Hastelloy C276 ndi aloyi C-276; ndi aloyi omwewo ndipo amangotchulidwa pogwiritsa ntchito njira zosiyanasiyana zotchulira mayina.
Hastelloy C22 ndi C-276 zonse ndi ma superalloy okhala ndi nickel okhala ndi zinthu zofanana.
Komabe, pali kusiyana kodziwika pakati pa ziwirizi: Kapangidwe: Hastelloy C22 ili ndi pafupifupi 56% nickel, 22% chromium, 13% molybdenum, 3% tungsten, ndi chitsulo chochepa, cobalt, ndi zinthu zina. Kumbali inayi, Hastelloy C-276 ili ndi pafupifupi 57% nickel, 16% molybdenum, 16% chromium, 3% tungsten, ndi chitsulo chochepa, cobalt, ndi zinthu zina. Kukana dzimbiri: Ma alloy onsewa amadziwika chifukwa cha kukana dzimbiri kwapadera.
Komabe, Hastelloy C-276 imapereka kukana dzimbiri bwino pang'ono kuposa C22 m'malo amphamvu kwambiri, makamaka motsutsana ndi zinthu zowononga monga chlorine ndi hypochlorite. C-276 nthawi zambiri imakondedwa pogwiritsidwa ntchito komwe kuli kowononga kwambiri. Kutha kusungunula: Hastelloy C22 ndi C-276 zonse ndi zosavuta kusungunula.
Komabe, C-276 ili ndi kuthekera kowotcherera bwino chifukwa cha kuchepa kwa kaboni, komwe kumapereka kukana bwino kukhudzidwa ndi kukhudzidwa ndi mpweya komanso kaboni ikalowa panthawi yowotcherera. Kuchuluka kwa kutentha: Ma alloy onsewa amatha kuthana ndi kutentha kwakukulu, koma C-276 ili ndi kutentha kwakukulu pang'ono. C22 nthawi zambiri imakhala yoyenera kutentha kogwira ntchito mpaka pafupifupi 1250°C (2282°F), pomwe C-276 imatha kuthana ndi kutentha mpaka pafupifupi 1040°C (1904°F). Ntchito: Hastelloy C22 imagwiritsidwa ntchito kwambiri m'mafakitale monga kukonza mankhwala, mankhwala, ndi kuyeretsa zinyalala. Ndi yoyenera bwino kuthana ndi mankhwala osiyanasiyana amphamvu, ma acid, ndi ma chloride. Hastelloy C-276, yokhala ndi kukana dzimbiri kwapamwamba, nthawi zambiri imasankhidwa kuti igwiritsidwe ntchito pofunikira kukana bwino ku malo osungunuka ndi kuchepetsa okosijeni, monga kukonza mankhwala, kuwongolera kuipitsa, ndi mafakitale amafuta ndi gasi.
Mwachidule, ngakhale kuti Hastelloy C22 ndi C-276 zonse ndi zipangizo zabwino kwambiri zogwiritsira ntchito malo owononga, C-276 nthawi zambiri imapereka kukana bwino dzimbiri m'malo owopsa kwambiri, pomwe C22 ndi yoyenera kwambiri kugwiritsa ntchito komwe kuwotcherera kapena kukana mankhwala ena ndikofunikira.Kusankha pakati pa ziwirizi kumadalira zofunikira zenizeni za pulogalamuyo.
