INCOLOY 825 (UNS N08825 / NS142)
Daim Ntawv Thov
Cov hlau nplaum 825 yog ib qho austenitic nickel-iron-chromium alloy uas kuj txhais los ntawm kev ntxiv molybdenum, tooj liab thiab titanium. Nws tau tsim los muab kev tiv thaiv zoo rau ntau qhov chaw corrosive, ob qho tib si oxidizing thiab txo qis.
Alloy 825 tau tsim los muab kev tiv thaiv zoo rau ntau qhov chaw corrosive, ob qho tib si oxidizing thiab txo qis. Nrog rau cov ntsiab lus nickel ntau ntawm 38% -46%, qib no qhia tau tias muaj kev tiv thaiv zoo rau kev ntxhov siab corrosion cracking (SCC) los ntawm chlorides thiab alkalis. Cov ntsiab lus nickel txaus rau kev tiv thaiv rau chloride-ion kev ntxhov siab-corrosion cracking. Lub nickel, ua ke nrog molybdenum thiab tooj liab, kuj muab kev tiv thaiv zoo rau kev txo qis ib puag ncig xws li cov uas muaj sulfuric thiab phosphoric acids.
Cov chromium thiab molybdenum cov ntsiab lus kuj muab kev tiv thaiv pitting zoo hauv txhua qhov chaw tshwj tsis yog cov tshuaj chloride oxidizing muaj zog. Siv ua cov khoom siv zoo hauv ntau yam txheej txheem ib puag ncig, alloy 825 tswj cov khoom siv kho tshuab zoo los ntawm qhov kub cryogenic txog li 1,000 ° F.
Qhov ntxiv ntawm titanium ua rau Alloy 825 ruaj khov tiv thaiv kev ua kom tsis muaj zog hauv qhov xwm txheej uas tau vuam ua rau cov hlau tiv taus kev tawm tsam intergranular tom qab raug rau qhov kub thiab txias hauv qhov ntau uas yuav ua rau cov hlau tsis ruaj khov tsis muaj zog. Kev tsim cov Alloy 825 yog ib txwm muaj ntawm cov hlau nickel-base, nrog rau cov khoom siv tau yooj yim tsim thiab weldable los ntawm ntau yam txheej txheem.
Cov khoom no muaj peev xwm ua tau zoo heev, ib txwm muaj cov hlau nickel-based alloys, uas ua rau cov khoom no khoov tau me me heev. Feem ntau tsis tas yuav tsum tau ua kom sov tom qab khoov.
Nws zoo ib yam li alloy 800 tab sis nws tau txhim kho kev tiv thaiv rau cov dej xeb. Nws muaj kev tiv thaiv zoo heev rau ob qho tib si txo qis thiab oxidizing acids, rau kev ntxhov siab-xeb tawg, thiab rau kev tawm tsam hauv zos xws li pitting thiab crevice corrosion. Alloy 825 tshwj xeeb tshaj yog tiv taus sulfuric thiab phosphoric acids. Cov hlau nickel no yog siv rau kev ua tshuaj lom neeg, cov khoom siv tswj kev ua qias tuaj, cov kav dej roj thiab roj av, kev ua dua tshiab roj nuclear, kev tsim kua qaub, thiab cov khoom siv pickling.
