Puas Yog Txhua Tus Hlau Stainless Hlau Sib Nqus?

Cov hlau tsis xebyog ib qho ntawm cov ntaub ntawv siv dav tshaj plaws hauv kev tsim kho niaj hnub, kev tsim khoom, thiab kev tsim vaj tsev. Nws paub txog nws qhov ruaj khov, tiv taus corrosion, thiab huv si zoo nkauj. Txawm li cas los xij, ib lo lus nug tseem ua rau muaj kev tsis meej pem ntawm cov neeg yuav khoom thiab cov engineers:Puas yog txhua cov hlau tsis xeb puas yog hlau nplaum?

Cov lus teb tsis yooj yim. Txawm hais tias qee cov hlau tsis xeb yog hlau nplaum, lwm cov tsis yog - thiab kev nkag siab txog vim li cas tuaj yeem ua qhov sib txawv loj thaum xaiv qib zoo rau koj qhov project. Hauv phau ntawv qhia ntxaws no,SAKYSTEELpiav qhia txog kev sib xyaw, cov qauv, thiab cov txheej txheem tsim khoom ntawm cov hlau tsis xeb txiav txim siab seb nws puas yog hlau nplaum lossis tsis yog.

1. Nkag Siab Txog Cov Hlau Stainless

Cov hlau tsis xeb yog ib qhohlau ua los ntawm hlauuas muaj tsawg kawg10.5% chromium, uas tsim ib daim zaj duab xis oxide nyias nyias, tsis pom ntawm qhov chaw. Cov txheej tiv thaiv no muab cov hlau tsis xeb nwszoo heev tsis kam rau xeb thiab corrosion.

Lwm cov ntsiab lus xws linickel, molybdenum, manganese, nitrogen, thiab carbonraug ntxiv los txhim kho cov yam ntxwv tshwj xeeb - xws li kev tawv, lub zog, thiab kev ua kom zoo nkauj.

Tab sis nws yog qhov sib xyaw ua ke ntawm cov ntsiab lus uas kuj cuam tshuamkev sib nqusNyob ntawm seb cov atoms tau teeb tsa li cas hauv cov hlau - qhovcov qauv siv lead ua— cov hlau tsis xeb tuaj yeem yog hlau nplaum lossis tsis yog hlau nplaum.

2. Kev Tshawb Fawb Tom Qab Magnetism hauv Stainless Steels

Lubcov khoom sib nqusntawm cov hlau tsis xeb feem ntau yog nyob ntawm nwscov qauv atomicKev sib nqus tshwm sim thaum lub zog sib nqus (kev tig ntawm cov electrons tsis muaj khub) hauv cov atoms sib dhos rau tib qho kev taw qhia.

Cov hlau tsis xeb muaj peev xwm muaj cov qauv siv lead ua sib txawv nyob ntawm lawv cov khoom sib xyaw thiab kev kho cua sov. Cov qauv no txhais lawv tus cwj pwm sib nqus.

Hom Hlau Stainless Cov Qauv Siv Crystal Sib nqus? Cov Qib Ib Txwm Muaj
Ferritic Lub cev-Centered Cubic (BCC) Muaj zog sib nqus 409, 430
Martensitic Lub cev-Centered Tetragonal (BCT) Muaj zog sib nqus 410, 420, 440C
Austenitic Lub ntsej muag-Centered Cubic (FCC) Tsis yog-Sib nqus 304, 316, 310, 321

3. Ferritic Stainless Steels: Muaj Magnetic Ntuj

Ferritic stainless hlaumuaj iblub cev-centered cubic (BCC)cov qauv zoo ib yam li hlau ntshiab, uas ua rau lawvmuaj zog sib nqus.

Lawv muaj chromium (10.5–18%) thiab me ntsis lossis tsis muaj nickel, yog li cov qauv tseem yog ferritic ntawm txhua qhov kub. Cov hlau no ua kezoo corrosion tsis kam nrog lub zog magnetic attraction.

Cov qib ferritic feem ntau muaj xws li:

  • AISI 409- Siv rau hauv cov tshuab pa tawm hauv tsheb thiab cov catalytic converters.

  • AISI 430- Pom muaj nyob rau hauv cov khoom siv hauv chav ua noj, cov khoom dai kom zoo nkauj, thiab cov khoom siv hauv tsev.

Cov hlau tsis xeb Ferritic yog hlau nplaum txhua lub sijhawm - ua ntej thiab tom qab tsim khoom - thiab siv dav thaum tsis muaj hlau nplaum.

4. Cov Hlau Stainless Martensitic: Sib Nqus thiab Nyuaj

Cov hlau tsis xeb Martensitickuj ua qauv qhiamuaj zog magneticLawv muaj ib tuglub cev tetragonal (BCT)cov qauv tsim los ntawmkev kho cua sov.

Cov hlau no muaj cov pa roj carbon ntau dua li cov qib ferritic, uas tso cai rau lawv kom ua tautawv los ntawm quenchingCov qauv tsim tawm yog ob qho tib si sib nqus thiab muaj zog heev.

Piv txwv li:

  • AISI 410- Cov hlau tsis xeb rau cov shafts thiab fasteners.

  • AISI 420- Feem ntau siv rau hauv cov cuab yeej phais thiab riam.

  • AISI 440C- Nyiam rau cov bearings thiab cov khoom siv high-precision.

Cov hlau Martensitic muab ib qhokev sib xyaw ua ke ntawm qhov nyuaj, lub zog, thiab magnetism, txawm hais tias lawv qhov kev tiv thaiv corrosion qis dua li cov hom austenitic.

5. Cov Hlau Stainless Austenitic: Tsis Yog Hlau Sib Nqus Los Ntawm Xwm

Cov hlau tsis xeb uas siv ntau tshaj plaws -AISI 304thiabAISI 316— koom nrogtsev neeg austenitic, uas muaj ib qholub ntsej muag-centered cubic (FCC)cov qauv siv lead ua. Qhov kev npaj ntawm cov atoms no tiv thaiv kev sib dhos ntawm cov electron spins, ua rau cov hlau austenitictsis yog hlau nplaum nyob rau hauv lub xeev annealed.

Lub ntsiab lus tseem ceeb uas ua rau tus cwj pwm no yognpib tsib, uas ua kom lub theem austenitic ruaj khov. Thaum cov hlau tsis xeb muaj nickel txaus (feem ntau yog 8–12%), nws tseem yog austenitic thiab tsis muaj hlau nplaum txawm tias nyob rau qhov kub qis.

Cov qib tsis yog hlau nplaum feem ntau suav nrog:

  • 304 / 304L- Cov hlau tsis xeb uas siv dav tshaj plaws, tsim rau kev siv dav dav.

  • 316 / 316L- Tiv taus cov dej hiav txwv thiab cov tshuaj lom neeg vim yog molybdenum.

  • 310 / 321- Tsim los rau cov ntawv thov kub heev.

Txawm li cas los xij, cov hlau austenitic tuaj yeem ua rau muaj kev phom sij.ua me ntsis magnetictom qabua haujlwm txias— xws li khoov, dov, lossis tsim — vim tias qee qhov austenite hloov mus uamartensite, uas yog hlau nplaum.

6. Vim li cas qee cov hlau tsis xeb "Tsis yog hlau nplaum" thiaj li ua hlau nplaum

Muaj ntau tus engineers xav tsis thoob thaum lub hlau nplaum tsis lo rau cov khoom siv hlau stainless 304. Qhov no tshwm sim vim yogkev hloov pauv ntawm lub cevthaum lub sijhawm tsim khoom.

Thaum cov hlau austenitic stainless hlau yogua haujlwm txias, qhov kev ntxhov siab ntawm lub tshuab ua rau nws cov crystal lattice hloov pauv thiab hloov qee qhov austenite (FCC) mus rau hauv martensite (BCT), uas yog magnetic.

Piv txwv li:

  • A 304 stainless hlau ntawvfeem ntau tsis yog hlau nplaum tom qab annealing.

  • Tom qabdov, kos duab tob, lossis ua haujlwm, nws yuav qhia taume ntsis magnetismntawm ntug lossis khoov.

  • Yog tias annealed dua, nws rov qab mus rau nws lub xeev tsis yog hlau nplaum.

Yog li ntawd,Cov hlau tsis xeb austenitic tsis yog 100% tsis muaj hlau nplaum tiag tiag, tab sis nws lub zog magnetism tsis muaj zog heev thiab thim rov qab tau.

7. Kev Sib Piv ntawm Cov Qauv Sib Nqus ntawm Cov Qib Sib Txawv

Qib Hom Kev coj cwj pwm sib nqus Cov Ntawv Thov Feem Ntau
430 Ferritic Muaj zog sib nqus Cov khoom siv, cov tshuab tso pa tawm
410 Martensitic Muaj zog sib nqus Cov twj siv, cov cuab yeej
304 Austenitic Tsis yog-sib nqus (tsis muaj zog tom qab ua haujlwm txias) Kev ua zaub mov, kev tsim vaj tsev
316 Austenitic Tsis yog hlau nplaum Cov khoom siv hauv dej hiav txwv thiab tshuaj lom neeg
420 Martensitic Muaj zog sib nqus Cov riam, cov hniav phais

Raws li tau qhia saum toj no, qhovmuaj nickelthiab lubhom kev kho cua sovtxiav txim siab seb qib twg yog hlau nplaum lossis tsis yog.

8. Kev Ntsuas Magnetism Hauv Cov Hlau Stainless

Txoj kev yooj yim tshaj plaws los xyuas seb cov khoom siv hlau tsis xeb puas yog hlau nplaum yog siv lubhlau nplaum me me tas mus liYog tias nws lo rau ruaj khov, cov khoom siv no yuav yog ferritic lossis martensitic. Yog tias nws lo tsis muaj zog lossis tsis lo kiag li, tej zaum nws yog austenitic.

Txawm li cas los xij,kev kuaj xyuas kev lag luamrau cov ntawv thov meej siv cov cuab yeej tshwj xeeb xws li:

  • Gaussmeters or cov ntsuas permeability sib nqus

  • Cov cuab yeej ntsuas Hall effect

  • ASTM A342 kev ntsuam xyuas permeability magnetic

Cov txheej txheem no ntsuas seb cov khoom siv tau magnetized yooj yim npaum li cas, hu ua nwspermeability sib nqus (μr).
Rau cov ntawv thov uas tsis yog hlau nplaum, μr yuav tsum nyob ze rau1.0, txhais tau tias cov khoom siv yuav luag tsis muaj kev teb magnetic.

At SAKYSTEEL, peb lub chaw kuaj mob tuaj yeem ua haujlwmKev kuaj permeability thiab microstructure magnetickom ntseeg tau tias cov khoom ua tau raws li cov neeg siv khoom xav tau rau ob qho tib si khoom sib nqus thiab tsis sib nqus.

9. Cov Ntawv Thov Qhov Twg Magnetism Tseem Ceeb
