Teb:
Nickel alloys, suav nrog Hastelloy, Incolel, Incoloy, thiab Monel, nthuav qhia cov khoom tseem ceeb hauv qab no:
High-kub lub zog: Nickel alloys tswj kev ncaj ncees cov qauv thiab lub zog ntawm kev nce kub, feem ntau txog 1,000 qib (1,800℃f) lossis siab dua.
Corrosion Kuj: cov alloys tau ua tau zoo heev rau ntau qhov chaw ntawm kev xeb ib puag ncig, suav nrog oxidation, pitting, thiab kev nyuaj siab-corrosion cracking.
Lub zog tensile: lub zog loj tensile muaj zog, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv thov 718 thiab hastelloy c276, ua rau kom lawv haum rau cov khoom siv hnyav thiab thauj khoom-cov kabmob yog qhov tseem ceeb.
Qoob loo: Nickel alloys, tshwj xeeb tshaj yog inconel 625 thiab main, ua rau lawv zoo tshaj rau cyclic thauj khoom hauv cov kav dej thiab hlab.
Ductility: alloys zoo li Incoloy zoo li Incoloy 800 muab cov qauv ua kom zoo, ua kom lawv yooj yim dua rau fab muag thiab daim ntawv rau hauv cov yeeb nkab thiab cov raj duab.
4. Ua li cas Hastelloy, incolel, thiab incoloy alloys sib piv nyob rau hauv cov nqe lus uas them cov ntawv thov thiab tubing?
Teb:
Feem ntau, tus nqi ntawm cov alloys txawv nyob ntawm lawv cov muaj pes tsawg leeg thiab cov khoom ua tau zoo tshwj xeeb:
Hastelloy: Hastelloy alloys nyiam nyob rau qhov siab dua ntawm tus nqi lub zog vim lawv cov ntsiab lus npib npe loj thiab molybdenum cov ntsiab lus, nrog rau lawv cov corrosion tsis kam. Hastelloy C276 thiab C22 yog cov nqi kim tshaj plaws tab sis yog qhov tsim nyog rau ib puag ncig cua hlob heev.
Inconel: Inconel alloys nyiam 625 thiab 718 yog tus nqi, corrosion tsis kam, thiab kav ntev, ua rau lawv raug nqi ntau yam kev siv ua haujlwm siab.
Incoloy alloys, xws li Incoloy 800, feem ntau yog pheej yig dua li cov kev xaiv kom kub thiab tsis tseem ceeb, tab sis tus nqi-efficiency yog qhov tseem ceeb.
Monel: Monel feem ntau kim dua cov qauv stainless hlau tab sis tsis tshua kim tshaj hastelloy. Nws yog qhov kev xaiv zoo rau cov tubrog nkoj thiab acidic ib puag ncig tab sis feem ntau raug nqi piv rau ntau cov alloys tshwj xeeb zoo li cov hastelloy.
5. Hastelloy, inconel, thiab monel yeeb nkab thiab cov khoom siv raj ua ke thaum lub sijhawm finerrication?
Teb:
Tsim kom zoo thiab fabrication ntawm hastelloy, inconel, thiab cov ntawv monel yog qhov tseem ceeb los tswj lawv txoj kev ua tau zoo thiab kev ncaj ncees:
Pre--cua sov thiab annealing: ib co alloys, zoo li inconel, tej zaum yuav xav tau ua cua sov lossis analing ua ntej vuam ib qho kev tawg thiab kev ntxhov siab. Nws yog qhov tseem ceeb los ua raws cov kev kho cua sov kom zoo.
Vuam: thaum vuam cov alloys no, siv cov khoom siv muab rau tsim nyog uas phim cov khoom siv uas tsim nyog (piv txwv li, inconel 625 tub muab tub lim rau inconel 625 kav dej). Ua kom ntseeg tau tias cov ris tsho tiv thaiv kom zoo (xws li Argon) kom tsis txhob muaj paug thiab oxidation thaum lub sij hawm vuam.
Corrosion tiv thaiv: txawm hais tias cov alloys yog corrosion-resistant, lawv tseem yuav tsum tau daws nrog kev saib xyuas kom tiv thaiv kom tsis txhob muaj kev paug los ntawm cov tshuaj uas cuam tshuam los ntawm kev tsim khoom. Nco ntsoov ntxuav cov chaw ua ntej ua haujlwm ntxiv.
Txias ua haujlwm: Thaum ntau ntawm cov alloys tau txias-ua haujlwm, ntau dhau ua haujlwm txias yuav tsum zam tiv thaiv kom tsis txhob tawg lossis embrittlement. Cov txheej txheem tswj tau xws li khoov thiab sib sau yuav tsum ua kom tsis txhob ua kom nruj.
Cov lus nug no thiab cov lus teb muab cov ntsiab lus ntawm hastelloy, incoly, qhia txog cov khoom siv raj, siv cov raj, thiab tuav cov ntawv thov rau ntau yam kev siv.
