Hastelloy C-276® i-alloy ye-nickel-molybdenum-chromium ene-corrosion resistant egqwesileyo kwiindawo ezinzima.Iziqulatho ze-nickel eziphezulu kunye ne-molybdenum zenza i-alloy yensimbi ye-nickel ixhathise ngokukodwa kwi-pitting kunye ne-crevice corrosion ekunciphiseni okusingqongileyo ngelixa i-chromium ihambisa ukuchasana ne-oxidizing media.Nangona kukho iinguqulelo ezininzi zeHastelloy nickel alloy, iHastelloy C-276 yeyona nto isetyenziswa kakhulu.
Isishwankathelo seempawu zeHastelloy C-276:
I-Hastelloy C-276 (N10276) inokumelana ne-corrosion egqwesileyo kwimithombo yeendaba ezininzi ezinobungozi phantsi kwe-oxidation kunye neemeko zokunciphisa.Ukuxhathisa okugqwesileyo kwi-corrosion, i-corrosion crevice kunye noxinzelelo lwe-corrosion cracking.I-alloy ifanelekile kumashishini ahlukeneyo enkqubo yeekhemikhali equkethe i-oxidizing kunye nokunciphisa imidiya.Umxholo ophezulu we-molybdenum kunye ne-chromium yenza i-alloy ixhathise ukubola yi-ion ye-chloride, kunye ne-element tungsten iphucula ngakumbi ukuxhathisa ukubola.
I-Hastelloy C-276 yenye yezinto kuphela ezinokuxhathisa ukubola kweklorini emanzi, i-hypochlorite kunye ne-chlorine dioxide isisombululo.I-alloy inokumelana ne-corrosion ebalulekileyo kwizisombululo zetyuwa ezixutywe ngeklorini (ezifana ne-Iron eklorini kunye nekloridi yobhedu).
