Qhov loj tau txais txiaj ntsig ntawm kev siv haastelloy c2000 yog nws txoj kev txhim kho kom haum rau lwm yam xws li C276 thiab C22, tshwj xeeb yog nyob rau hauv ib puag ncig uas yog ob qho kub thiab muaj kev sib zog. Qhov no ua rau nws zoo tagnrho rau kev thov siv rau kev ua tshuaj lom neeg uas muaj ib puag ncig kev ua haujlwm siab yog qhov tseem ceeb.
3. Dab tsi ua rau Hastelloy B2 thiab B3 zoo rau cov kua qaub heev?
Teb:
Hastelloy B2 thiab B3 yog ob qho tshwj xeeb alloys tsim los siv nyob rau hauv cov chaw muaj kev tiv thaiv uas tsis tshua muaj, tshwj xeeb tshaj yog muaj cov kua roj hydrochloric acid. Tus yuam sij sib txawv thiab cov txiaj ntsig zoo ntawm txhua tus:
Hastelloy B2: Cov alloy no ua rau hydrochloric acid thoob plaws ntau yam ntawm cov kev ua kom muaj zog thiab qhov zoo tshaj plaws rau kev siv cov kua qaub ruaj khov. Nws tiv taus pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking, uas yog cov teeb meem ntau hauv cov acidic ib puag ncig.
Hastelloy B3: Kev txhim kho B2, Hastelloy B3 tswj hwm tib yam kev ntxhov siab rau cov kev ntxhov siab ib puag ncig (ESC) thiab txhim kho weldability. B3 feem ntau siv hauv kev lag luam tshuaj, suav nrog rau kev tsim cov tshuaj tiv thaiv, kev sib pauv cua sov, thiab cov twj tso pa tawm hauv cov acidic ib puag ncig.
4. Vim li cas inconel thiab monel alloys feem ntau siv rau high- qhov kev siv kub?
Teb:
Ob leeg Inconel thiab Monel alloys muaj feem ntau siv nyob rau hauv high- lub zog thiab corrosion tsis kam rau qhov kub siab:
Inconel: inconel alsoys, xws li inconel 625 thiab inconel 718, ua rau lawv zoo tshaj plaws rau aerospace, thiab kev siv tshuaj lom neeg. Cov alloys tswj kom muaj lub zog kho tshuab muaj zog txawm nyob hauv cov cheeb tsam heev (txog li 2000℃F lossis 1093 degree).
Monel: Monel alloys, zoo li Monel 400, yog feem ntau - tooj liab alloys paub txog ob qho siab- kub thiab dej hiav txwv ib puag ncig. Thaum lawv tsis tiv thaiv kub siab li incine, lawv feem ntau siv hauv kev ua yeeb yam, thiab lub zog ntawm kev txhim kho thiab lub zog ntawm kev nce siab kub.
Ob alloys tau siv nyob rau hauv cov khoom sib xyaw ua ke, kev hloov pauv cua sov, thiab reactor cov hlab ntsha uas muaj zog rau kev cuam tshuam cua sov thiab ua rau thermal degradation yog qhov tseem ceeb heev.
5. Dab tsi yog cov txiaj ntsig ntawm kev siv seamless nickel - tooj liab allooy leeg thiab kav dej hauv kev lag luam?
Teb:
Seamless tsibckel - tooj liab allooy leeg thiab kav dej muab ob peb qhov zoo, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj kev lag luam:
Corrosion Kuj: Nickel - tooj liab alloys (zoo li meel thiab hastelloy) muab cov acidic, tshwj xeeb} Nplua. Qhov no ua rau lawv zoo tshaj plaws rau kev ua yeeb yam, cov ntawv thov marrine, thiab lwm yam kev lag luam uas qhov kev ua tsis tau zoo yog qhov tseem ceeb.
Siab zog thiab durability: cov alloys tswj lub zog siab, uas yog qhov tseem ceeb rau kev siv nyob rau hauv kev lag luam zoo li aerospace, thiab petrochemical refining.
Weldability thiab covricability: seamless hlab thiab kav dej yooj yim dua rau fab me me, uas txo qhov kev pheej hmoo ntawm qhov tsis xws luag los yog ua tsis tiav ntawm cov ntawv thov tseem ceeb.
Ntev -}} term kev ntseeg tau: lub durability thiab tsis kam rau kev ntxhov siab ntawm kev ua phem thiab kev ua haujlwm ntev thiab txo cov nqi kho ntev thiab txo tus nqi kho ntev thiab txo tus nqi kho ntev thiab txo tus nqi kho ntev thiab txo tus nqi kho ntev thiab txo tus nqi kho ntev thiab txo tus nqi kho ntev thiab txo tus nqi kho ntev thiab txo tus nqi kho ntev.
Cov alloys no, tshwj xeeb tshaj yog nyob rau hauv seamless tub thiab yeeb yaj kiab, muab cov txiaj ntsig tseem ceeb hauv cov ntawv thov kev lag luam siab. Qhia rau kuv paub yog tias koj xav tau cov ntsiab lus ntxiv!
