Puas yog Stainless Hlau 304 Sib Nqus? Magnetism piav qhia

Lus Teb luv luv

Tsis yog, 304 stainless hlau feem ntau tsis yog- hlau nplaum vim nws yog austenitic alloy nrog lub ntsej muag -centered cubic crystal qauv. Txawm li cas los xij, nws tuaj yeem dhau los ua cov hlau nplaum me ntsis tom qab cov txheej txheem ua haujlwm txias xws li khoov, shaping, lossis kos duab, uas ua rau muaj kev hloov pauv ntawm microstructure.

Austenitic piv rau Lwm Cov Qauv

Cov qauv austenitic ntawm 304 tsis yog- sib nqus, tsis zoo li cov tsev neeg ferritic, martensitic, thiab duplex stainless hlau, uas yog sib nqus vim lawv lub cev -centered cubic los yog cov qauv sib xyaw. Qhov no yog vim li cas ib tug hlau nplaum lo rau ib tug 430 riam hniav los yog ib tug 410 ncej tab sis tsis mus rau annealed 304 daim ntawv.

Qhov cuam tshuam ntawm Kev Ua Haujlwm Txias

Cov txheej txheem uas deform cov hlau tuaj yeem ua rau muaj kev hloov pauv, tsim kom muaj me me ntawm cov hlau nplaum sib nqus -induced martensite. Qhov ntau cov hlau ua haujlwm, ntau cov ntaub ntawv martensite thiab qhov sib nqus ntau dua. Khoov, kos duab sib sib zog nqus, thiab kev sib sau hnyav yog qhov chaw ntawm cov nyhuv no.

Yuav Ua Li Cas Rov Qab Los

Cov hlau nplaum induced tuaj yeem thim rov qab los ntawm kev daws teeb meem annealing, uas ua rau cov hlau ua kom sov rau hauv qhov chaw austenitizing thiab tom qab ntawd txias sai, thim rov qab martensite rov qab mus rau qhov tsis yog -magnetic austenitic xeev. Qhov kev kho no tseem rov ua kom muaj kev tiv thaiv corrosion cuam tshuam los ntawm deformation.

Daim ntawv thov cuam tshuam

Rau cov ntawv thov uas muaj hlau nplaum tseem ceeb, xws li kev kho mob ib puag ncig lossis cov khoom siv ua zaub mov nrog cov khoom siv hlau nplaum, annealed 304 yog qhov kev xaiv tsim nyog. Qhov twg yuav tsum muaj cov lus teb muaj zog sib nqus, xws li cov hniav riam lossis cov khoom sib nqus, cov qib sib nqus zoo li 430 zoo dua.
