Inco 825 Cov Khoom Siv Neeg Kho Tshuab
Lub zog: nws muaj lub zog tensile zoo, nrog cov nuj nqis uas raug rau ib ncig ntawm {{mpa mpa hauv anealed mob. Cov txiaj ntsig lub zog feem ntau yog nyob rau thaj tsam ntawm 290 - 352 mpa.
Ductility: Incoloy Alloy 825 Daim Phiaj Kev Pom Zoo ductility, nrog kev elongation ntawm ib ncig ntawm {1}}%. Qhov no tso cai rau kev tsim kho yooj yim thiab cov hlua khi ua ntau yam duab thiab cov qauv.
Tougness: Nws muaj cov khoom zoo zoo, ua kom nws withstand cuam tshuam thiab dynamic chaw thau khoom tsis muaj nkig tsis ua tiav.
Corrosion Kuj
General corrosion resistance: nws qhia tau zoo tshaj plaws rau ntau yam ntawm kev xeb ib puag ncig. Nws yog cov muaj zog heev rau cov kua qaub xws li sulfuric acid, hydrochloric acid, thiab phosphoric acid, txawm tias nyob rau siab kub thiab ntau dua. Nws tseem muaj qhov tsis zoo rau cov kev daws teeb meem alkaline.
Pitting thiab crevice corrosion resistance: lub alloy muaj qhov siab tiv taus pitting thiab crevice corrosion vim nws cov tshuaj lom neeg tshwj xeeb thiab microstructure. Qhov no ua rau nws haum rau cov ntawv thov uas cov khoom raug tawm tsam cov xov xwm ua kom nruj nrog cov chaw kaw lossis tsis muaj kev daws teeb meem.
Kev ntxhov siab corrosion tawg tsis kam: incoloy alloy 825 tau ua rau muaj kev ntxhov siab corrosion (SCC) hauv ntau qhov chaw, suav nrog cov uas muaj chlorides thiab sulfides. Cov cuab yeej no yog qhov tseem ceeb hauv kev tiv thaiv kev tiv thaiv tam sim ntawd thiab kev puas tsuaj hauv cov chaw ntxhov siab.
Cov Ntawv Thov
Kev Lag Luam Kev Lag Luam: Nws yog dav siv nyob rau hauv cov cuab yeej siv rau forrosive tshuaj, xws li reactors, kev tso tsheb hlau hluav taws xob, thiab kev tso tsheb hlau taws. Nws corrosion tsis kam thiab kub tiv taus ua rau nws zoo tagnrho rau cov txheej txheem uas muaj ntau hom acids thiab siab - kev kub siab.
Roj thiab roj kev lag luam: Incoloy alloy 825 daim hlau yog siv nyob rau hauv cov cuab yeej siv hauv downhole, tshwj xeeb tshaj yog nyob rau hauv cov kua uas muaj roj - teb brines thiab qaub roj av. Nws txoj kev tawm tsam rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking yog qhov tseem ceeb rau kev ntseeg tau thiab ntev ntawm cov feem no.
Kev kho dej: Nws yog haujlwm hauv cov nroj tsuag dej nyab thiab cov dej kho, tshwj xeeb hauv cov khoom siv uas muaj kev sib cuag dej hiav txwv lossis lwm yam dej. Nws corrosion resistance pab kom tiv thaiv thaum ntxov ua tsis tiav thiab ua kom muaj kev ncaj ncees ntawm cov cuab yeej.
Kev ua khoom noj: Vim tias nws tsis yog - tshuaj lom thiab xeb cov khoom siv ua kom huv si, nws yog siv rau kev ua zaub mov huv thiab tiv thaiv kom corrosion yog qhov tseem ceeb.
