Vim li cas cov hlau tsis xeb tsis yog hlau nplaum?

Cov hlau tsis xeb yog lub npe nrov rau nws txoj kev tiv taus xeb, ruaj khov, thiab zoo nkauj. Txawm li cas los xij, ib qho ntawm cov lus nug feem ntau nug yog:vim li cas cov hlau tsis muaj hlau nplaumCov lus teb nyob rau hauv cov qauv sab hauv thiab cov khoom sib xyaw ntawm cov hlau tsis xeb sib txawv. Tsis yog txhua cov hlau tsis xeb tsis yog hlau nplaum, tab sis qee qhov qib siv dav tshaj plaws, xws li 304 thiab 316, tsis nyiam cov hlau nplaum hauv qab cov xwm txheej ib txwm muaj.

Hauv tsab xov xwm no, peb yuav tshawb nrhiav seb vim li cas qee cov hlau tsis xeb tsis muaj hlau nplaum, cov qib twg yog hlau nplaum, thiab cov khoom no cuam tshuam li cas rau kev siv hauv ntiaj teb tiag. Ua tus kws tshaj lij muag khoom hlau tsis xeb,sakysteelpab cov neeg siv khoom nkag siab txog tus cwj pwm ntawm cov khoom siv kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws.

Nkag Siab Txog Magnetism Hauv Cov Hlau

Kev sib nqus hauv cov hlau nyob ntawm lawv cov qauv atomic. Cov ntaub ntawv uas muaj cov electrons tsis sib txuas, xws li hlau, cobalt, thiab nickel, suav tias yog ferromagnetic. Cov hlau no sib dhos lawv cov chaw sib nqus hauv qhov muaj lub teb sib nqus thiab tuaj yeem nyob twj ywm magnetized.

Cov hlau tsis xeb yog ib qho hlau sib xyaw ua los ntawm hlau, uas yog hlau nplaum. Txawm li cas los xij, lwm cov khoom sib xyaw xws li chromium thiab nickel hloov nws cov qauv sab hauv, uas tuaj yeem txhim kho lossis txo cov khoom sib nqus.

Lub Luag Haujlwm ntawm Cov Qauv Crystal

Tus yuam sij rau seb cov hlau tsis xeb puas yog hlau nplaum lossis tsis yog nyob rau hauv nwscov qauv siv lead uaCov hlau tsis xeb tau muab faib ua ntau tsev neeg sib txawv:

• Austenitic

• Ferritic

• Martensitic

• Ob chav

• Nag los khov kho (PH)

Austenitic Stainless Steel - Tsis Muaj Magnetic

Cov qib xws li304thiab316poob rau hauv qeb austenitic. Cov hlau no muaj cov theem siab ntawmnpib tsib, uas ua kom lub cev ruaj khovlub ntsej muag-centered cubic (FCC)qauv. Cov qauv no tsis txhawb nqa magnetism, ua rau cov qib notsis yog hlau nplaumnyob rau hauv lub annealed mob.

Piv txwv li:

• 304 Cov Hlau StainlessTsis yog hlau nplaum vim nws cov qauv austenitic.

• 316 Cov Hlau Stainless: Tsis tas li ntawd, tsis yog hlau nplaum thiab tiv taus xeb ntau dua vim yog ntxiv molybdenum.

Cov no yog cov hom hlau tsis xeb uas siv ntau tshaj plaws hauv cov khoom siv hauv chav ua noj, cov khoom siv vaj tse, thiab cov cuab yeej kho mob.

Puas Austenitic Stainless Steel Ua Tau Magnetic

Yog lawm, nyob rau hauv qee qhov xwm txheej, txawm tias cov hlau tsis xeb austenitic tuaj yeem ua rau pomlub zog magnetic tsis muaj zogQhov no tshwm sim thaum cov khoom siv dhau los ua haujlwm txias, xws li khoov, tsim, lossis ua haujlwm. Cov txheej txheem no tuaj yeem ua rau muaj kev hloov pauv theem los ntawm austenite mus raumartensite, uas yog hlau nplaum.

Txawm li cas los xij, qib ntawm magnetism tseem qis thiab feem ntau tsis cuam tshuam rau kev ua tau zoo. Kev kho cua sov lossis annealing tuaj yeem kho cov khoom tsis yog magnetic.

Ferritic thiab Martensitic Stainless Steels - Sib Nqus

Tsis zoo li cov qib austenitic,ferriticthiabmartensiticcov hlau tsis xeb yogsib nquslos ntawm xwm.

• Ferritic Stainless Hlau(piv txwv li, 430): Muaj chromium tab sis me ntsis lossis tsis muaj nickel, muaj iblub cev-centered cubic (BCC)qauv, thiab yog sib nqus.

• Martensitic Stainless Hlau(piv txwv li, 410, 420): Kuj tseem muaj hlau nplaum thiab tawv tau los ntawm kev kho cua sov.

Cov qib no yog siv rau qhov twg cov khoom sib nqus xav tau lossis lees txais, xws li hauv cov khoom siv thiab cov khoom siv tsheb.

Vim Li Cas Cov Hlau Stainless Uas Tsis Muaj Magnetic Tseem Ceeb

Qhov xwm txheej tsis muaj hlau nplaum ntawm austenitic stainless hlau muaj txiaj ntsig zoo rau ntau daim ntawv thov:

• Cov Khoom Siv Kho MobCov cuab yeej uas tsis yog hlau nplaum yog qhov tseem ceeb rau cov chav MRI.

• Khoom siv hluav taws xobTiv thaiv kev cuam tshuam nrog cov teb sib nqus hauv cov khoom siv rhiab heev.

• Kev tsav dav hlauSiv rau hauv cov khoom uas yuav tsum txo qis kev sib cuam tshuam ntawm cov hlau nplaum.

• Cov Kev Siv Nuclear: Txo qhov kev cuam tshuam los ntawm lub zog sib nqus.

At sakysteel, peb muab cov kev daws teeb meem stainless hlau uas tsim los rau cov lag luam uas xav tau kev ua haujlwm zoo, suav nrog cov qib tsis sib nqus rau cov ntawv thov tshwj xeeb.

Kev Ntsuas rau Magnetism

Ib txoj kev yooj yim los sim qhov magnetism yog siv lub hlau nplaum yooj yim. Yog tias nws lo rau ntawm cov hlau stainless hlau, qib ntawd yuav yog ferritic lossis martensitic. Yog tias tsis muaj qhov rub lossis tsis muaj zog heev, nws yuav yog qib austenitic zoo li 304 lossis 316.

Rau kev kuaj xyuas kom raug, tshwj xeeb tshaj yog tom qab tsim khoom, lub ntsuas gauss tuaj yeem siv los ntsuas qhov ceev ntawm cov khoom sib nqus.
