High Temperature Alloy
High Temperature Alloy
◆GH2132 (incoloyA-286/S66286) ili ndi ntchito yabwino yonse komanso malire okolola ambiri.Amagwiritsidwa ntchito popanga ma turbine discs, mabwalo a mphete, ma welds amabulaketi ndi zida zolipirira zida zosachepera 700 ° C.
◆ GH3030 alloy ali ndi dongosolo lokhazikika, kukalamba kochepa, komanso kukana bwino kwa okosijeni.Ndi yoyenera kuzipinda zoyaka ndi zoyatsira moto pansi pa 800 ° C.
◆GH3128 ili ndi ntchito yabwino yokwanira, yolimba kwambiri, kukana kwa okosijeni, kukhazikika kwadongosolo komanso ntchito yabwino yowotcherera, ndipo imagwiritsidwa ntchito makamaka pachipinda choyatsira moto ndi mbali zina za injini ya turbine yokhala ndi kutentha kwa 950 ° C.
◆GH4145 (inconelx-750/N07750) ili ndi mphamvu zokwanira, kukana kwa dzimbiri ndi kukana kwa okosijeni pansi pa 980 ° C.Ndizinthu zomwe zimakonda kwambiri akasupe amphamvu kwambiri ndipo ndizoyenera kupanga ma diaphragms zotanuka ndi mapepala osindikizira.
◆GH4169 (N07718/inconel718) ili ndi mawonekedwe austenite, ndipo gawo la "Y" lomwe limapangidwa pambuyo pa kuuma kwa mvula limapangitsa kuti likhale ndi makina abwino kwambiri.Amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana omwe ali ndi zofunika kukana kutentha kwambiri.
◆GH4080A (N07080/Nimonic80A)Z ili ndi kutentha kwakukulu kokwanira pa 700-750 ° C ndi kukana kwa mpweya wabwino pansi pa 900 ° C.Aloyi yapaderayi ndi yoyenera kuminda yomwe imafuna mphamvu zambiri komanso kukana dzimbiri.
◆GH3044 Chipinda chachikulu choyaka moto ndi zida zamoto, zishango zotentha, zowongolera, ndi zina.
◆GH4080A ili ndi kukana kwabwino kwa kukwawa komanso kukana kwa okosijeni mumitundu ya 650-850 ° C.
◆GH2136 ili ndi ntchito yabwino yonse, mawonekedwe okhazikika pambuyo pogwiritsidwa ntchito kwa nthawi yayitali, kukana kwa okosijeni kwabwino, kokwanira kakang'ono kakukulirakulira, komanso kuwotcherera kosavuta ndi kupanga.
◆ GH2036 Turbine discs, zishango za kutentha, mphete zosungira, mphete zonyamula, zomangira, ndi zina zomwe zimagwira ntchito pansi pa 650 ° C.
◆GH4738 ndiyoyenera kupanga ma turbine discs, masamba ogwirira ntchito, zomangira zotentha kwambiri, machubu amoto, ma shafts ndi ma turbines, ndi zina zambiri.
