Yog sus321 stainless hlau sib nqus?

Sib nqus cov khoom ntawm sus321 stainless hlau (Austenitic Stainless hlau, sib npaug rau Astm 321)

Lub cev sib nqus ntawm sus321 stainless hlau yog ze rau nws cov qauv siv lead ua thiab ua kom muaj mob. Kev tsom xam yog raws li hauv qab no:

---

1. Sus321 Stainless Hlau Kev Siv-Annealed (Annealed) mob

Crystal Qauv: Tom qab daws teeb meem (feem ntau yog cov mob uas siv), sus321 muaj ib qho kev ntsuas microstructic. Austenite yog inherently tsis yog-sib nqus, nrog sib nqus permeability ze rau ntawm lub tshuab nqus tsev (μ ≈ 1).

Sib Nqus Cwj Pwm: Nws cov khoom pov thawj tsis pom zoo cov hlau nplaum, lossis tsuas yog tsis muaj zogua paramagnetism(Yuav tuaj yeem nyiam me ntsis nyob rau hauv ib qho chaw sib nqus muaj zog, tab sis loses Magnetism thaum thaj teb raug tshem tawm).

2.Sus321 Stainless Hlau Txias Ua Haujlwm

Cov nyhuv ntawm kev ua: Yog hais tias cov khoom siv undergoes txias deformation (piv txwv li cov kev kos txias, khoov, khoov), ib co ntawm Austenite yuav hloov mus rau martensite, uas yog ferromagnetic. Qhov kev hloov pauv no tuaj yeem qhia cov hlau nplaum me ntsis rau cov khoom siv.

Lub zog nqus zog: Lub txiaj ntsig zoo tshaj plaws yog feem ntau tsis muaj zog - cov ntaub ntawv tej zaum yuav faintly nyiam rau lub zog hlau nplaum muaj zog. Cov lus teb sib nqus nce nrog tus nqi ntawm kev ua haujlwm txias (piv txwv li, qhov ntau dua qhov deformation, lub zog ntawm cov hlauetism).

3. Sus321 Stainless Hlau Tswv yim txiav txim hauv kev siv

Tsis yog sib nqus ib puag ncig: Rau cov ntawv thov uas yuav tsum muaj kev sib nqus tsis muaj kev sib nqus, cov khoom siv kho mob), nws raug xa mus rau cov lus qhia txog kev sib nqus ntawm cov khoom siv.

Magnetism tom qab ua haujlwm txias: Me hlau me me tsis feem ntau cuam tshuam rau kev kub siab lossis corrosion-resistant yam ntxwv, tab sis yuav tsum tau ntsuas hauv cov ntawv thov sib cuam tshuam hauv hluav taws xob.

Kev thim rov qab ntawm Magnetism: Martensite tsim thaum lub sijhawm ua haujlwm txias tuaj yeem rov qab mus rau Austenite los ntawm kev siv kub siab (daws kev kho mob), ua kom muaj txiaj ntsig cov lus teb sib nqus.

Daws-annealed sus321: Tsis muaj ib qho tseem ceeb siv hlau nplaum (tuav los ntawm cov qauv Austenitic).

Khaub thuas-ua haujlwm sus321: Tej zaum yuav ua rau pom kev hloov pauv me me (vim yog martensitic kev hloov pauv), txawm tias ntau tsis muaj zog tshaj ferritic lossis martensitic stainless hlau.

Kawg cov khoom sib nqus: Ua raws li cov khoom siv tshwj xeeb (qib ntawm kev ua haujlwm txias) thiab yuav tsum tau lees paub los ntawm kev kuaj mob sib nqus (piv txwv li, μ tus nqi ntsuas).
