Hastelloy yog dab tsi?
Hastelloy yog dab tsi?
Hastelloy yog ib qho corrosion-resistant nickel hlau alloy nrog ntxiv molybdenum thiab chromium. Nws cov qib sib txawv yog tsim los rau cov khoom tshwj xeeb, muab kev tiv thaiv corrosion zoo, weldability zoo, thiab tsis kam mus rau oxidants thiab acids. Cov ntsiab lus siab molybdenum txhim kho kev ua haujlwm tau zoo, ua rau Hastelloy nyiam dua lwm cov hlau tshwj xeeb xws li Incoloy® nyob rau hauv ib puag ncig corrosive hnyav.
Hastelloy yog dab tsi?
Cov ntsiab lus tseem ceeb ntawm Hastelloy yog 13% molybdenum, 22% chromium, thiab 56% npib tsib xee. Nws kuj muaj qhov sib txawv ntawm cov hlau, nyob ntawm qhov sib txawv; thiab tej zaum kuj yuav muaj cov kab ntawm cobalt thiab tungsten. Hastelloy qhov zoo heev corrosion kuj tshwm sim los ntawm nws cov alloy muaj pes tsawg leeg (rau txhua qhov sib txawv).
Hastelloy ua li cas?
Kev tsim khoom ntawm Hastelloy suav nrog ntau cov txheej txheem. Nws pib nrog smelting, nrog nruj tswj cov tshuaj muaj pes tsawg leeg xws li npib tsib xee (kwv yees li 56%), molybdenum ({2}}%), chromium (14.5-16.5%) thiab hlau (4-7%). ), ua kom pom kev ua haujlwm zoo. Txhua qhov sib txawv ntawm alloy. Cov kev hloov pauv sib txawv tuaj yeem muaj feem ntau sib txawv kom tau raws li cov kev xav tau tshwj xeeb. Tom ntej no los casting, siv cov tsis meej kom ua tiav cov qauv, tsis muaj qhov tsis xws luag. Kev kho cua sov tuaj yeem kho cov microstructure thiab txhua yam khoom. Thaum kawg, kev ua haujlwm suav nrog kev ua haujlwm txias thiab kub, xaiv raws li kev thov tshwj xeeb, txhawm rau txhim kho Hastelloy cov khoom zoo dua.
Dab tsi yog qhov txawv ntawm Hastelloy?
Hastelloy yog hais txog ib tsev neeg ntawm nickel-raws li alloys uas yog corrosion-resistant thiab tsim rau kev siv tshwj xeeb. Molybdenum-nplua nuj Hastelloy B-3 tiv taus huab cua siab thiab acids. C-4 nthuav tawm kev tiv thaiv corrosion hauv cov tshuaj chloride, thaum Hastelloy C muaj hluav taws xob zoo heev. C-276 sawv tawm rau nws lub peev xwm los tiv thaiv ntau yam ntawm cov txheej txheem tshuaj, ua rau nws zoo tagnrho rau ib puag ncig hnyav. C-22 yog ib qho zoo tagnrho txhuas alloy nrog zoo corrosion kuj.
Qhov zoo ntawm Hastelloy yog dab tsi?
Qhov zoo ntawm Hastelloy muaj xws li:
Cov hlau yog yooj yim rau vuam, yooj yim rau kev tsim cov txheej txheem thiab tso cai rau cov khoom sib koom ua ke zoo yam tsis muaj kev cuam tshuam rau cov khoom siv corrosion-resistant.
Kev tiv thaiv zoo heev rau hauv cheeb tsam corrosion, tiv thaiv kev sib txuas tsis muaj zog hauv qee qhov chaw thiab ua kom muaj kev ntseeg siab ntawm cov khoom tseem ceeb cuam tshuam los ntawm cov khoom corrosive.
Hastelloy qhov muaj zog tiv thaiv tsis zoo rau kev tawm tsam muab kev ua haujlwm ntev hauv cov kab mob corrosive, tiv thaiv kev yaig ntawm qhov chaw thiab ua kom muaj kev ntseeg ruaj khov txawm tias raug tshuaj abrasive.
Hastelloy ua rau muaj kev sib tw ntau dua los ntawm kev ua tau raws li cov txheej txheem tsim khoom, ua rau kev tsim cov khoom siv thiab cov khoom siv ruaj khov. Nws lub peev xwm los hloov cov duab nce qhov tseeb thiab kev ua haujlwm ntawm cov txheej txheem ntau lawm.
Vim tias Hastelloy muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion tawg, nws tiv thaiv kev ncaj ncees ntawm cov khoom thiab tiv thaiv kev pib thiab kev nthuav tawm ntawm cov kab nrib pleb uas tuaj yeem rhuav tshem cov khoom hauv kev ntxhov siab thiab corrosive ib puag ncig.
Dab tsi yog qhov tsis zoo ntawm Hastelloy?
Disadvantages ntawm Hastelloy muaj xws li:
Kev cuam tshuam rau kev ntxhov siab xws li vuam lossis machining tuaj yeem ua rau muaj kev ntxhov siab tawg thiab muaj peev xwm tiv thaiv tsis ua haujlwm.
Vim yog tus nqi siab ntawm Hastelloy, nrhiav kev muab khoom ntawm Hastelloy tuaj yeem nyuaj, tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li kev lag luam tshuaj.
Tsis sib xws nrog cov hlau lead lossis zinc, txwv tsis pub nws siv hauv cov ntawv thov uas muaj cov ntaub ntawv no.
Vim tias Hastelloy yog qhov nyuaj rau qhov tawv thiab brittleness, cov ntawv thov uas yuav tsum tau siv ntau lub tshuab tsis haum rau Hastelloy.
Puas yog Hastelloy zoo dua Monel?
Yuav tsis. Thaum Hastelloy muaj kev tiv thaiv corrosion zoo heev, Monel kuj muaj nws qhov zoo, muab lub zog siab thiab tawv. Monel yog tsim rau ib puag ncig tshwj xeeb, xws li kev siv dej hiav txwv. Qhov kev xaiv ntawm Hastelloy thiab Monel nyob ntawm qhov kev xav tau tshwj xeeb ntawm qhov project, suav nrog cov yam ntxwv xws li lub zog, kev tiv thaiv corrosion thiab tus nqi.
