I-Hastelloy B Nickel Alloy
I-Hastelloy B(UNS N10001) iyingxubevange ye-nickel-molybdenum (Ni-Mo) eklanyelwe ngokukhethekile ukwehlisa kakhulu izindawo ezibolayo (njenge-hydrochloric acid ne-sulfuric acid). Ibonisa ukumelana okuhle kakhulu{4}kumazinga okushisa aphezulu, i-hydrochloric acid, ne-sulfuric acid corrosion, kodwa ayimelani nemidiya ye-oxidizing (njenge-nitric acid). Ilungele ukusetshenziswa kumishini yamakhemikhali, izinhlelo zokuhlanza i-asidi, nezinye izinhlelo zokusebenza.

Isici
I-Hastelloy B yakhelwe ukuphromotha ukwakheka -kwesigaba se-Ni₄Mo ngokunciphisa okuqukethwe kwe-iron ne-chromium, ngaleyo ndlela kuthuthukiswe ukwakheka kwayo okuncane. Ibonisa ukumelana nokugqwala okuvelele ezindaweni ezinciphisayo, ikakhulukazi ngokumelene ne-sulfuric acid egxilile eningi kanye nohlu olubanzi lwama-asidi{2}}angewona oxidizing. Ukwengeza, ingxubevange inikeza ukumelana okuhle kakhulu ne-stress corrosion cracking (SCC) edalwe ama-ion e-chloride, kanye nokumelana okuphakeme nama-asidi aphilayo ahlukahlukene, okuyenza ibe into eguquguqukayo futhi ekwazi ukumelana nokugqwala{4}}.
Izinhlelo zokusebenza
I-Hastelloy B iyingxubevange yamahhala ye-chromium{0}eklanyelwe ukusetshenziswa kusevisi ye-hydrochloric acid. Ifanele{{2}ifanele{3}}izinhlelo zokusebenza zengcindezi ephezulu kuma-turbines, ukumelana namazinga okushisa afika ku-760℃ezindaweni ezixutshwa ne-oxidizing futhi ephakeme nakakhulu ezimweni zokunciphisa. Izicelo ezijwayelekile zihlanganisa amabhawodi namashafu kumaturbine egesi asebenza ngaphansi kwezimo ezibolayo noma{6}}eziphezulu.
