I-INCOLOY 825 (UNS N08825 / NS142)
Isicelo
I-Alloy 825 yi-alloy ye-nickel-iron-chromium e-austenitic ekwachazwa ngokongezwa kwe-molybdenum, i-copper kunye ne-titanium. Yenzelwe ukubonelela ngokumelana okugqwesileyo kwiindawo ezininzi ezirhabaxa, zombini ukuxovula kunye nokunciphisa.
I-Alloy 825 yaphuhliswa ukuze inike ukumelana okugqwesileyo kwiindawo ezininzi ezibolayo, zombini ukuxovula kunye nokunciphisa. Ngoluhlu lomxholo we-nickel oluphakathi kwe-38%–46%, olu didi lubonisa ukumelana okucacileyo kokuqhekeka koxinzelelo (SCC) okubangelwa zii-chloride kunye ne-alkalis. Umxholo we-nickel wanele ukumelana nokuqhekeka koxinzelelo-ukubola kwe-chloride-ion. I-nickel, kunye ne-molybdenum kunye ne-copper, ikwanika ukumelana okugqwesileyo kwiindawo ezinciphisayo ezifana nezo ziqulethe i-sulfuric kunye ne-phosphoric acids.
Umxholo we-chromium kunye ne-molybdenum ukwabonelela ngokumelana okuhle kwemingxuma kuzo zonke iindawo ngaphandle kwezisombululo ze-chloride ezixidayo kakhulu. Isetyenziswa njengesixhobo esisebenzayo kwiindawo ezahlukeneyo zenkqubo, i-alloy 825 igcina iipropati ezilungileyo zoomatshini ukusuka kumaqondo obushushu aqinileyo ukuya kuthi ga kwi-1,000° F.
Ukongezwa kwe-titanium kuzinzisa i-Alloy 825 ngokuchasene nokuziva xa ikwimeko edibeneyo, nto leyo eyenza ukuba i-alloy imelane nokuhlaselwa yi-intergranular emva kokuvezwa kumaqondo obushushu akwinqanaba eliya kwenza ukuba i-stainless steels ezingazinzanga zizive ziziva ziziva. Ukwenziwa kwe-Alloy 825 kuqhelekile kwii-alloys ze-nickel-base, apho izinto zilungele ukwakheka kwaye zithungelwa ngeendlela ezahlukeneyo.
Le nto inokwakheka okuhle kakhulu, okufana nee-alloys ze-nickel-base, okuvumela ukuba into igotywe ibe zii-radii ezincinci kakhulu. Ukuyibopha emva kokugoba akusoloko kuyimfuneko.
Ifana ne-alloy 800 kodwa iphucule ukumelana nokugqwala kwamanzi. Iyakwazi ukumelana kakuhle ne-asidi zokunciphisa kunye ne-oxidizing, ukuqhekeka koxinzelelo kunye nokugqwala, kunye nokuhlaselwa kwendawo efana nokugqwala kwemigodi kunye nokugqwala kwe-crevice. I-alloy 825 iyakwazi ukumelana ngakumbi ne-sulfuric kunye ne-phosphoric acids. Le alloy yentsimbi ye-nickel isetyenziselwa ukucubungula iikhemikhali, izixhobo zokulawula ungcoliseko, imibhobho yeoyile kunye negesi, ukuphinda kusetyenziswe amafutha enyukliya, ukuvelisa i-asidi, kunye nezixhobo zokucoca.
