INCOLOY 825 (UNS N08825 / NS142)
Isicelo
I-alloy 825 yi-alloy ye-nickel-iron-chromium ye-austenitic ekwachazwa ngezongezo ze-molybdenum, ubhedu kunye ne-titanium. Yaphuhliswa ukunika ukuxhathisa okukhethekileyo kwiindawo ezininzi ezinobungozi, zombini i-oxidizing kunye nokunciphisa.
I-alloy 825 yaphuhliswa ukunika ukuxhathisa okukhethekileyo kwiindawo ezininzi ezinobungozi, zombini i-oxidizing kunye nokunciphisa. Ngoluhlu lomxholo we-nickel phakathi kwe-38% -46%, eli bakala libonisa ukuchasana okucacileyo kwi-stress corrosion cracking (SCC) eyenziwa yi-chlorides kunye ne-alkali. Umxholo we-nickel wanele ukuchasana ne-chloride-ion stress-corrosion cracking. I-nickel, ngokubambisana ne-molybdenum kunye nobhedu, ikwanika ukuchasana okubalaseleyo ekunciphiseni iimeko ezifana nezo ziqulethe i-sulfuric kunye ne-phosphoric acids.
Isiqulatho sechromium kunye nemolybdenum ikwabonelela ngokuchaneka kakuhle komngxuma kuzo zonke iindawo ngaphandle kwezisombululo zekloride ene-oxidizing. Isetyenziswa njengesixhobo esisebenzayo kwiindawo ezahlukeneyo zenkqubo, i-alloy 825 igcina iipropathi ezilungileyo zomatshini ukusuka kumaqondo obushushu e-cryogenic ukuya kuthi ga kwi-1,000 ° F.
Ukongezwa kwe-titanium kuzinzisa i-Alloy 825 ngokuchasene nokuqonda kwimeko ye-aswelded eyenza i-alloy imelane nohlaselo lwe-intergranular emva kokuvezwa kumaqondo obushushu kuluhlu oluya kuvuselela iintsimbi ezingenazinzingo ezingenazinza. Ukwenziwa kwe-Alloy 825 kufana ne-nickel-base alloys, kunye nezinto eziphathekayo ezinokubakho ngokukhawuleza kunye ne-weldable ngeendlela ezahlukeneyo.
Esi sixhobo sinokubunjwa okugqwesileyo, okuqhelekileyo kwe-nickel-base alloys, evumela izinto ukuba zigobe kwiradiyi encinci kakhulu. Ukuhlanjululwa emva kokugoba akuyomfuneko ngokuqhelekileyo.
Ifana ne-alloy 800 kodwa iphucule ukuxhathisa kwi-aqueous corrosion. Inokumelana okugqwesileyo kokubini ekunciphiseni kunye ne-oxidizing acids, kuxinzelelo lwe-corrosion cracking, kunye nohlaselo lwasekhaya olufana ne-pitting kunye ne-crevice corrosion. I-alloy 825 ixhathisa ngokukodwa kwi-sulfuric kunye ne-phosphoric acids. Le ngxubevange yensimbi yenickel isetyenziselwa ukusetyenzwa kweekhemikhali, izixhobo zokulawula ungcoliseko, imibhobho ye-oyile nerhasi, ukucutshungulwa kwamafutha enyukliya, ukuveliswa kweasidi, kunye nezixhobo zokuchola.
