2. Monel 400 piv rau Incoloy 800 li cas ntawm kev tiv thaiv corrosion thiab kub ua haujlwm?
Teb:
Monel 400 (UNS N04400) yog npib tsib xee - tooj liab alloy uas ua tau zoo nyob rau hauv marine ib puag ncig vim nws zoo heev tiv thaiv dej hiav txwv corrosion, chlorides, thiab sulfuric acid. Nws kuj tiv thaiv kev ntxhov siab corrosion tawg nyob rau hauv ib puag ncig chloride thiab tswj lub zog ntawm qhov kub siab txog 1000℃F (537 degree).
Incoloy 800 (UNS N08800) yog npib tsib xee - hlau-chromium alloy tsim los rau siab - cov ntawv siv kub qhov twg oxidation kuj thiab creep zog yog qhov tseem ceeb. Nws yog feem ntau siv rau hauv qhov cub, cov khoom siv hluav taws xob, thiab cov tshuab hluav taws xob nuclear thiab tsim nyog rau txog li 1800℃F (982 degree).
Qhov txawv ntawm qhov tseem ceeb: Thaum Monel 400 yog qhov tsim nyog rau kev siv dej hiav txwv thiab tshuaj lom neeg, Incoloy 800 ua tau zoo dua nyob rau hauv siab - qhov kub thiab txias ntawm kev lag luam ib puag ncig xav tau oxidation tsis kam thiab thermal stability.
3. Dab tsi ua rau Incoloy 840 haum rau siab -kev siv kub, thiab nws siv li cas?
Teb:
Incoloy 840 yog npib tsib xee-chromium alloy tsim los siv nyob rau hauv qhov chaw siab - kub. Nws muaj qhov zoo oxidation tsis kam, creep kuj, thiab txhua yam muaj zog ntawm qhov kub thiab txias, ua rau nws zoo tagnrho rau kev lag luam xws li:
Thaum tshav kub kub exchangers, furnaces, thiab turbine hniav nyob rau hauv lub zog tsim kev lag luam.
Gas thiab chav turbines nyob rau hauv aerospace thiab lub zog tsim sectors, qhov twg cov Cheebtsam yog raug rau huab cua kub thiab kev nyuaj siab.
Incoloy 840 yog qhov tshwj xeeb tshaj yog rau cov ntawv thov uas yuav tsum tau muaj zog tuav ntawm qhov kub txog li 1000℃(1832℃F).
4. Dab tsi yog qhov zoo ntawm kev siv Inconel 600 hauv kev lag luam kev lag luam, thiab qhov twg nws feem ntau siv?
Teb:
Inconel 600 (UNS N06600) yog npib tsib xee -chromium alloy nrog oxidation zoo heev thiab corrosion kuj ntawm qhov kub thiab txias. Nws tuav nws lub zog thiab corrosion kuj txawm nyob rau hauv oxidizing ib puag ncig thiab siab - kub.
Cov ntawv thov suav nrog cov tshuab hluav taws xob, cov khoom siv hluav taws xob, thiab cov tshuaj reactors, nrog rau cov roj turbines thiab nuclear reactors.
Nws yog tshwj xeeb tshaj yog zoo nyob rau hauv siab -kub daim ntaub ntawv uas tsis kam mus oxidation thiab creep kuj yog ib qho tseem ceeb, ua rau nws haum rau cov khoom raug rau combustion gases thiab kub hnyav (txog 2000℃F / 1093℃).
5. Dab tsi ua rau Hastelloy C276 Coil thiab Monel 400 Coil zoo tagnrho rau cov ntawv thov uas yuav tsum muaj kev tiv thaiv corrosion siab hauv cov tshuaj lom neeg nruj heev?
Teb:
Hastelloy C276 yog ib qho ntawm feem ntau corrosion-cov alloys resistant muaj thiab yog dav siv nyob rau hauv cov ntaub ntawv uas muaj chlorides, sulfuric acid, thiab siab - kub tej yam kev mob. Nws ua tau zoo nyob rau hauv ib puag ncig nruj xws li kev ua tshuaj lom neeg, kev kho cov khib nyiab, thiab kev tsim tshuaj, qhov twg lwm cov ntaub ntawv yuav ua tsis tau vim pitting los yog kev nyuaj siab corrosion cracking.
Monel 400 muaj kev tiv thaiv zoo heev rau cov dej hiav txwv thiab cov tshuaj chlorides, ua rau nws yog qhov kev xaiv zoo tshaj plaws nyob rau hauv marine ib puag ncig, roj thiab roj, thiab tshuaj lom neeg kev lag luam uas yuav tsum tau muaj kev tiv thaiv corrosion rau ob qho tib si txo thiab oxidizing cov neeg ua haujlwm. Nws yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv cov ntawv thov uas muaj kev ntxhov siab corrosion tawg tuaj yeem ua rau muaj kev txhawj xeeb.
Ob lub alloys muab qhov ntev - kav ntev nyob rau hauv ib puag ncig uas muaj corrosive heev, ua kom ntseeg tau thiab txo qhov kev xav tau ntawm kev saib xyuas tsis tu ncua.
