I-INCOLOY 825 (UNS N08825 / NS142)
Isicelo
I-Alloy 825 iyi-alloy ye-nickel-iron-chromium e-austenitic futhi echazwa ngokwengezwa kwe-molybdenum, ithusi kanye ne-titanium. Yakhelwe ukuhlinzeka ngokumelana okungavamile ezindaweni eziningi ezigqwalisayo, kokubili ukuxilisa kanye nokunciphisa.
I-Alloy 825 yathuthukiswa ukuze inikeze ukumelana okungavamile ezindaweni eziningi ezigqwalisayo, kokubili ukuxova kanye nokunciphisa. Njengoba okuqukethwe yi-nickel kuphakathi kuka-38%–46%, leli banga libonisa ukumelana okukhulu kokuqhekeka kokugqwala kokucindezeleka (SCC) okubangelwa ama-chloride nama-alkali. Okuqukethwe yi-nickel kwanele ukumelana nokuqhekeka kokugqwala kokucindezeleka kwe-chloride-ion. I-nickel, ngokubambisana ne-molybdenum kanye nethusi, iphinde inikeze ukumelana okuvelele ezindaweni ezinciphisayo njengalezo eziqukethe ama-sulfuric kanye nama-phosphoric acid.
Okuqukethwe kwe-chromium kanye ne-molybdenum nakho kunikeza ukumelana okuhle kokufaka imigodi kuzo zonke izindawo ngaphandle kwezixazululo ze-chloride ezikhipha i-oxidation enamandla. Isetshenziswa njengento ephumelelayo ezindaweni eziningi zenqubo, i-alloy 825 igcina izakhiwo ezinhle zomshini kusukela emazingeni okushisa acwebezelayo afinyelela ku-1,000° F.
Ukwengezwa kwe-titanium kuzinzisa i-Alloy 825 ngokumelene nokuzwela esimweni esishisiwe okwenza i-alloy imelane nokuhlaselwa kwe-intergranular ngemva kokuchayeka emazingeni okushisa asezingeni elingase lizwele izinsimbi ezingagqwali ezingazinzile. Ukwenziwa kwe-Alloy 825 kujwayelekile kuma-alloy e-nickel-base, lapho izinto zikwazi ukwakheka kalula futhi zishiselwe ngamasu ahlukahlukene.
Le nto inokwakheka okuhle kakhulu, okufana nama-alloy e-nickel-base, okuvumela ukuthi into igobe ibe yi-radii encane kakhulu. Ukugoba ngemva kokugoba ngokuvamile akudingeki.
Ifana ne-alloy 800 kodwa ithuthukise ukumelana nokugqwala kwamanzi. Inamandla kakhulu okumelana nama-asidi okunciphisa kanye noku-oxidative, ukuqhekeka kokugqwala kokucindezeleka, kanye nokuhlaselwa kwendawo efana nokugqwala kwemigodi kanye nokugqwala kwemisele. I-alloy 825 imelana kakhulu nama-asidi e-sulfuric kanye ne-phosphoric. Le alloy yensimbi ye-nickel isetshenziselwa ukucubungula amakhemikhali, imishini yokulawula ukungcola, amapayipi kawoyela negesi, ukucubungula kabusha uphethiloli wenuzi, ukukhiqizwa kwe-asidi, kanye nemishini yokuqoqa.
