Stainless hlau txiav kev faib tawm kev ua tau zoo

Kev faib tawm raws li microstructure thiab kev kho cua sov ntawm cov hlau tsis huv yog cov txheej txheem feem ntau rau kev faib tawm ntawm cov hlau txiav txiav kev ua tau zoo. Qhov kev faib tawm no faib tag nrho cov hlau tsis huv rau hauv peb pawg, uas yog cov hlau tsis muaj zog (martensitic stainless hlau) thiab cov hlau tsis tawv (Ferritic stainless hlau), austenitic stainless hlau. Txhua ntawm peb pawg no suav nrog qee qib txiav hlau dawb. Tam sim no peb pawg ntawm cov hlau tsis huv tau qhia luv luv raws li hauv qab no:

Thawj pawg: tawv stainless hlau (martensitic stainless hlau)

Hom hlau tsis huv no yog tsim los ntawm 400 kab ntawm cov hlau hlau uas tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov. Ntawm lawv, txiav dawb hom hlau tsis huv yog: 416, 420F, 440F; kev txiav dav dav yog 403, 410, 420, 431, 440A, 440B, 440C Etc; tag nrho cov saum toj no cov hlau yog martensitic stainless hlau, yog li lawv sib nqus hauv lub xeev annealed; lawv tuaj yeem raug tua thiab ua kom sov kom ua tiav ntau yam nyuaj. Hom hlau no yog qhov yooj yim tshaj plaws los txiav thiab txheej txheem yog 416 thiab 416F, qhov nyuaj tshaj plaws yog txiav 440C, vim tias cov ntsiab lus carbon siab ntawm 440C hlau yuav ua rau hnav hnyav ntawm cov cuab yeej txiav.

Pawg thib ob: cov hlau tsis xeb hlau (ferritic stainless hlau)

Hom hlau tsis huv no suav nrog cov hlau hauv 400 series uas tsis tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov. Cov qauv ntawm cov hlau no yog ferrite, yog li lawv kuj yog sib nqus hauv lub xeev annealed. Ntawm lawv, muaj 430F rau dawb txiav cov hlau tsis xeb; cov uas muaj kev txiav txiav dav dav yog: 405, 430, 446

Pawg thib peb: austenitic stainless hlau

Hom hlau tsis huv no yog hu ua nickel-chromium 300 series stainless hlau. Tsis ntev los no, lawv cov peev txheej tau nthuav dav kom suav nrog ntau Cr-Ni-Mn cov hlau hauv 200 series. Cov qauv txheej txheem ntawm cov hlau no yog austenite, yog li nws tsis yog hlau nplaum thiab tsis tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov. Txawm li cas los xij, feem ntau ntawm cov hlau tsis huv no muaj qhov ua haujlwm siab tawv, uas yog qhov ntau dua li cov hlau tsis muaj ferritic thiab martensitic.

Ntawm cov hlau no, 303 thiab 303Se tuaj yeem txiav tau yooj yim. Nws kuj suav nrog qee tus qauv austenitic stainless hlau, xws li 201, 202, 301, 302, 304, 305, 308, 309, 310, 316, 317, 321, 347, thiab lwm yam. suav nrog hauv cov qauv hauv tebchaws. Piv nrog rau feem ntau martensitic lossis ferritic stainless hlau, kev txiav ntawm austenitic stainless hlau tsis yooj yim dua. Qhov sib txawv tseem ceeb yog tias cov hlau austenitic stainless nyob hauv lub xeev me me uas tau muab txhuam tau yog nplaum heev thiab txiav. Kev ua haujlwm feem ntau tsim cov fibrous txiav tej daim, uas tsuas tuaj yeem zam tau los ntawm kev siv cov txheej txheem tshwj xeeb. Ib qho ntxiv, kev ua haujlwm siab tawv tawv thaum ua haujlwm tseem yuav ua rau txiav nyuaj.
