1. Cov ntawv thov tseem ceeb ntawm Incoloy 800/800HT hlau yog dab tsi?
Teb:
Incoloy 800/800HT hlau yog siv rau hauv daim ntawv thov uas yuav tsum tau muaj corrosion kuj, thermal stability, thiab mechanical zog. Cov kev siv ib txwm muaj xws li:
Cov khoom cua sov nyob rau hauv industrial furnaces thiab tshav kub exchangers
Gas turbine Cheebtsam thiab cov khoom siv fais fab nroj tsuag
Kev siv tshuaj thiab petrochemical
Nuclear thiab marine daim ntaub ntawv raug rau kub kub thiab corrosive xov xwm
Springs, fasteners, thiab hlau cov ntaub ntawv nyob rau hauv siab - ib puag ncig kev nyuaj siab
2. Dab tsi ua rau Incoloy 800/800HT hlau zoo tshaj rau tus qauv stainless hlau xaim?
Teb:
Kev tiv thaiv zoo heev rau oxidation thiab carburization ntawm qhov kub siab
Cov ntsiab lus nickel siab (30-35%) muab kev tiv thaiv zoo rau kev ntxhov siab corrosion tawg
Molybdenum thiab hlau tshuav nyiaj li cas txhim khu lub zog thiab corrosion kuj
Ua tau zoo nyob rau hauv ob qho tib si oxidizing thiab txo qis ib puag ncig, tsis zoo li cov qauv stainless hlau (304, 316) uas yuav ua tsis tau raws li qhov kub thiab txias lossis tshuaj lom neeg.
3. Dab tsi yog qhov tseem ceeb ntawm cov khoom siv ntawm annealed Incoloy 800/800HT hlau?
Teb:
Lub zog tensile siab, feem ntau 550-700 MPa nyob ntawm txoj kab uas hla thiab kev ua haujlwm
Tawm lub zog ntawm kwv yees li 200-350 MPa
Zoo heev ductility, cia khoov, coiling, thiab sib sau tsis muaj cracking
Ua kom muaj kev ncaj ncees ntawm kev ua haujlwm siab ntawm qhov kub siab txog 700℃rau 800HT
Kev qaug zog zoo rau cov xaim nyob rau hauv cyclic loading tej yam kev mob
4. Yuav ua li cas Incoloy 800/800HT hlau yuav tsum tau ua los yog fabricated?
Teb:
Annealing: Restores ductility tom qab txias ua hauj lwm; Feem ntau ua tiav ntawm 980-1140℃tom qab txias ceev.
Vuam: Siv cov nickel{0}}raws li cov hlau; preheating feem ntau tsis tas yuav tsum tau vim muaj cov ntsiab lus carbon tsawg.
Khoov / sib sau: Hlau tuaj yeem tsim rau hauv coils, springs, lossis cov duab nyuaj yam tsis tau poob lub zog tom qab annealing kom raug.
Kev kho deg: Ntxuav thiab passivation tuaj yeem txhim kho corrosion kuj nyob rau hauv ib puag ncig hnyav.
5. Dab tsi yuav tsum tau xav txog thaum xaiv Incoloy 800/800HT hlau rau ib qhov project?
Teb:
Kev khiav hauj lwm kub: 800HT variant yog qhov zoo dua rau kev ua haujlwm siab ntev - qhov kub thiab txias.
Corrosive ib puag ncig: Tsim nyog rau oxidizing thiab txo qis ib puag ncig; xaiv raws li kev raug tshuaj lom neeg.
Mechanical load: Tensile thiab yield zog yuav tsum tau raws li qhov yuav tsum tau ua, tshwj xeeb tshaj yog rau springs los yog fasteners.
Kev tsim thiab fabrication xav tau: Hlau yuav tsum tau annealed rau txoj kev, coiling, los yog dabtsi yog khoov yam tsis muaj cracking.
Tus nqi-kev ua tau zoo: Muab kev pabcuam ntev dua hauv qhov chaw hnyav, txo cov nqi kho thiab hloov pauv piv rau cov hlau tsis muaj steel hlau.
