I-INCOLOY 825 (UNS N08825 / NS142)
Isicelo
I-alloy 825 iyingxubevange ye-nickel-iron-chromium ye-austenitic futhi echazwe ngokwengezwa kwe-molybdenum, ithusi ne-titanium. Yakhelwe ukunikeza ukumelana okuyingqayizivele ezindaweni eziningi ezigqwalayo, kokubili i-oxidizing kanye nokunciphisa.
I-alloy 825 yathuthukiswa ukuze inikeze ukumelana okuyingqayizivele ezindaweni eziningi ezigqwalayo, kokubili i-oxidizing kanye nokunciphisa. Ngebanga lokuqukethwe kwe-nickel eliphakathi kuka-38%–46%, leli banga libonisa ukumelana nokuqhekeka kwe-stress corrosion cracking (SCC) okudalwe ama-chloride nama-alkali. Okuqukethwe kwe-nickel kwanele ukumelana nokuqhekeka kwe-chloride-ion stress-corrosion. I-nickel, ngokuhlanganyela ne-molybdenum nethusi, iphinde inikeze ukumelana okuvelele ekunciphiseni izindawo ezifana nalezo eziqukethe i-sulfuric ne-phosphoric acid.
Okuqukethwe kwe-chromium ne-molybdenum nakho kunikeza ukumelana okuhle kwe-pitting kuzo zonke izindawo ngaphandle kwezixazululo ze-chloride ezixube kakhulu. Isetshenziswa njengento ephumelelayo ezindaweni ezihlukahlukene zenqubo, ingxubevange engu-825 igcina izakhiwo ezinhle zemishini kusukela emazingeni okushisa e-cryogenic afika ku-1,000 ° F.
Ukwengezwa kwe-titanium kuzinzisa i-Alloy 825 ngokumelene nokuzwela esimweni esinamathelisi okwenza ingxubevange imelane nokuhlaselwa kwe-intergranular ngemva kokuchayeka emazingeni okushisa ebangeni obungathulisa izinsimbi ezingenasici ezingaqinile. Ukwenziwa kwe-Alloy 825 kufana nengxubevange ye-nickel-base, into ekwakheka kalula futhi ishiseleke ngamasu ahlukahlukene.
Le nto inokwakheka okuhle kakhulu, okujwayelekile kwama-alloys esisekelo se-nickel, okuvumela okokusebenza ukuthi kugotshwe kumarediya amancane kakhulu. Ukukhipha isisu ngemva kokugoba ngokuvamile akudingekile.
Ifana ne-alloy 800 kodwa ithuthukise ukumelana nokugqwala kwe-aqueous. Inokumelana okuhle kakhulu nakho kokubili ukunciphisa kanye ne-oxidizing acid, ukuqhekeka kwe-stress-corrosion, kanye nokuhlaselwa kwendawo okufana nokugqwala nokugqwala kwemifantu. Ingxubevange 825 imelana ikakhulukazi ne-sulfuric kanye ne-phosphoric acid. Le ngxubevange yensimbi ye-nickel isetshenziselwa ukucubungula amakhemikhali, izinto zokulawula ukungcoliswa komhlaba, amapayipi omthombo kawoyela negesi, ukucutshungulwa kabusha kukaphethiloli wenuzi, ukukhiqizwa kwe-asidi, kanye nemishini yokucosha.
