INCOLOY 825 (UNS N08825 / NS142)
Codsiga
Alloy 825 waa austenitic nikkel-iron-chromium alloy sidoo kale lagu qeexay ku darida molybdenum, copper iyo titanium. Waxaa loo sameeyay si ay u bixiso iska caabin aan caadi ahayn oo ku wajahan deegaanno badan oo daxalka ah, labadaba oksaydheynta iyo dhimista.
Alloy 825 waxaa loo sameeyay si ay u bixiso iska caabin gaar ah oo ku wajahan bey'ado badan oo daxalka, labadaba oxidizing iyo yaraynta. Iyada oo ay ku jirto maadada nikkel inta u dhaxaysa 38%-46%, fasalkani waxa uu soo bandhigayaa iska caabin cad oo loogu talagalay dildilaaca daxalka (SCC) ee ay sababaan chlorides iyo alkalis. Waxa ku jira nikkelku waa ku filan yahay iska caabinta chloride-ion stress-corrosion dildilaaca. Nikkel, oo ay weheliyaan molybdenum iyo naxaas, ayaa sidoo kale bixiya iska caabin heersare ah si loo yareeyo bay'ada sida kuwa ay ku jiraan asiidhyada sulfuric iyo phosphoric.
Waxa ku jira chromium iyo molybdenum sidoo kale waxay bixiyaan iska caabin wanaagsan oo deegaanka oo dhan ah marka laga reebo xalalka oksaydhka ee xooggan. Loo isticmaalo sidii walax wax ku ool ah oo noocyo badan oo geeddi-socod deegaaneed ah, Alloy 825 waxa ay haysaa sifooyin farsamo oo wanaagsan laga bilaabo heerkulka cryogenic ilaa 1,000 ° F.
Ku darida titanium-ka waxay xasilinaysaa Alloy 825 ka soo horjeeda dareenka xaaladaha is-welded taasoo ka dhigaysa daawaha u adkeysaneysa weerarka intergranular ka dib marka la soo bandhigo heerkul kala duwan taas oo dareensiin doonta birta aan xasiloonayn ee birta ah. Soo saarista Alloy 825 waa mid ka mid ah alloysyada nikkel-saldhigga, iyada oo alaabtu ay tahay mid diyaarsan oo la farsamayn karo oo lagu alxan karo farsamooyin kala duwan.
Qalabkani wuxuu leeyahay qaab-dhismeed heer sare ah, oo ka mid ah alwaaxyada nikkel-saldhigga, taas oo u oggolaanaysa maaddada in loo leexiyo radis aad u yar. Annealing ka dib foorarsiga caadi ahaan looma baahna.
Waxay la mid tahay daawaha 800 laakiin waxay hagaajisay iska caabinta daxalka aqueous. Waxay leedahay iska caabin heer sare ah oo ay u leedahay dhimista iyo oksaydhaynta aysiidhka labadaba, dillaaca stress-daxalka, iyo weerarka gudaha sida daxalka daloolka iyo dillaaca. Alloy 825 wuxuu si gaar ah u adkaystaa asiidhyada sulfuric iyo phosphoric. Daawaha birta nikkel waxa loo isticmaalaa habaynta kiimikaad, qalabka lagu xakameeyo wasakhowga, tuubooyinka saliidda iyo gaasta ceelka, dib u habaynta shidaalka nukliyeerka, wax soo saarka aashitada, iyo qalabka wax lagu qaado.
