Puas yog Stainless Hlau Sib Nqus?

Taw qhia

Stainless hlau yog dav paub rau nws corrosion kuj thiab sleek tsos, tab sis ib tug nquag nug cov lus nug yog:Puas yog stainless hlau magnetic?Cov lus teb tsis ncaj ncees - nws nyob ntawm qhovhomthiabsiv lead ua qauvntawm stainless hlau. Hauv phau ntawv qhia no, peb yuav tshawb xyuas cov khoom sib nqus ntawm cov qib stainless hlau sib txawv, qhia meej cov kev xav tsis zoo, thiab pab cov engineers, cov neeg yuav khoom, thiab DIYers paub txog kev xaiv.

Dab tsi ua cov khoom sib nqus?

Ua ntej dhia mus rau hauv cov hlau tsis muaj steel, cia saib seb qhov twg txiav txim siab seb cov khoom puas yog hlau nplaum. Ib qho khoom siv yogSib nqusyog tias nws tuaj yeem raug nyiam rau cov hlau nplaum lossis hlau nplaum. Qhov no tshwm sim thaum cov khoom muajunpaired electronsthiab acrystalline qauvuas tso cai rau magnetic domains mus dlhos.

Cov ntaub ntawv raug faib ua peb hom magnetic:

• Ferromagnetic(magnetic heev)

• Paramagnetic(tsis muaj zog magnetic)

• Diamagnetic(tsis magnetic)

Cov qauv ntawm Stainless hlau: Ferrite, Austenite, Martensite

Stainless hlau yog ibhlau alloymuaj chromium thiab qee zaum nickel, molybdenum, thiab lwm yam khoom. Nws cov khoom sib nqus nyob ntawm nwsmicrostructure, uas poob rau hauv cov pawg hauv qab no:

1. Austenitic Stainless Hlau (Non-Magnetic los yog Weakly Magnetic)

• Cov Qib304, 316, 310, 321

• QauvLub ntsej muag-Centered Cubic (FCC)

• Sib nqus?: Feem ntau tsis-magnetic, tab sis kev ua haujlwm txias (xws li, khoov, machining) tuaj yeem ua rau me ntsis hlau nplaum.

Austenitic stainless hlau yog cov khoom siv ntau tshaj plaws hauv cov khoom siv hauv chav ua noj, cov kav dej, thiab cov cuab yeej kho mob vim lawv cov corrosion kuj zoo heev thiab ductility.

2. Ferritic Stainless hlau (Magnetic)

• Cov Qib430, 409, ib.446 ib

• Qauv: Lub Cev-Centered Cubic (BCC)

• Sib nqus?: Yog lawm, ferritic hlau yog hlau nplaum.

Lawv feem ntau yog siv nyob rau hauv tsheb qhov chaw, cov khoom siv hauv tsev, thiab cov ntawv thov kev lag luam uas muaj kev tiv thaiv corrosion txaus txaus.

3. Martensitic Stainless hlau (Magnetic)

• Cov Qib: 410, 420, 440C

• QauvLub Cev-Centered Tetragonal (BCT)

• Sib nqus?: Yog lawm, cov no yog magnetic heev.

Martensitic steels paub txog lawv qhov hardness thiab feem ntau siv hauv riam, txiav cov cuab yeej, thiab cov khoom siv turbine.

Puas yog 304 lossis 316 Stainless Hlau Sib Nqus?

Nov yog ib qho ntawm cov lus nug uas tau tshawb nrhiav. Nov yog qhov sib piv ceev:

Yog li, yog tias koj tab tom nrhiavnon-magnetic stainless hlau, 304 thiab 316 yog koj thawj koom ruam zoo tshaj plaws-tshwj xeeb tshaj yog nyob rau hauv lawv cov mob annealed.

Vim li cas nws tseem ceeb yog tias Stainless hlau yog hlau nplaum?

Nkag siab seb qib stainless hlau puas yog hlau nplaum yog qhov tseem ceeb rau:

• Cov khoom siv ua zaub mov: qhov twg magnetism tuaj yeem cuam tshuam nrog cov tshuab.

• Cov cuab yeej kho mob: xws li MRI cov cav tov, qhov twg cov ntaub ntawv uas tsis yog hlau nplaum yuav tsum tau.

• Cov khoom siv: rau compatibility nrog magnetic attachments.

• Industrial fabrication: qhov twg weldability lossis machining tus cwj pwm hloov raws li tus qauv.

Yuav Ua Li Cas Ntsuas Stainless Hlau Magnetism

Txhawm rau xyuas seb cov hlau tsis muaj hlau tsis sib nqus:

1. Siv cov hlau nplaum- Muab nws rau saum npoo. Yog nws sticks nrees, nws yog magnetic.

2. Ntsuam xyuas thaj chaw sib txawv– Welded los yog txias-ua hauj lwm cheeb tsam yuav qhia ntau magnetism.

3. Txheeb xyuas qib- Qee zaum, cov nqi qis dua yog siv yam tsis muaj ntawv sau npe.

Tsis-magnetic stainless hlau xaim hlua Magnetic test

Peb tau soj ntsuam cov hlau tsis sib nqus ntawm cov hlau tsis muaj hlau hlua ntawm ntau txoj kab uas hla thiab cov ntaub ntawv kom ua tau raws li cov qauv sib nqus hlau tsis zoo uas yuav tsum tau ua hauv cov ntawv thov tseem ceeb xws li MRI chav, kev siv tub rog, thiab kev ntsuas qhov tseeb.

Qhov kev ua yeeb yaj kiab yeeb yaj kiab no nthuav tawm peb cov txheej txheem kev ntsuas sib nqus, paub tseeb tias peb cov hlua khi-ua los ntawm cov qib xws li 316L thiab 304 stainless hlau-tsim cov khoom tsis sib nqus txawm tias tom qab tsim thiab tsim khoom.

Stainless hlau puas tuaj yeem ua hlau nplaum dhau sijhawm?

Yog lawm.Ua haujlwm txias(bending, sib sau, machining) tuaj yeem hloov microstructure ntawm austenitic stainless hlau thiab qhiaferromagnetic zog. Qhov no tsis tau txhais hais tias cov khoom tau hloov qib - nws tsuas yog txhais tau tias qhov saum npoo tau dhau los ua hlau nplaum me ntsis.

Xaus

Yog li ntawd,yog stainless hlau magnetic?Cov lus teb yog:Qee tus yog, qee qhov tsis yog.Nws nyob ntawm qib thiab kev kho mob.

• Austenitic (304, 316) Cov.: Tsis-sib nqus hauv daim ntawv annealed, me ntsis sib nqus tom qab ua haujlwm txias.

• Ferritic (430)thiabMartensitic (410, 420): Sib nqus.

Thaum xaiv stainless hlau rau koj daim ntawv thov, xav txogob qho tib si nws corrosion kuj thiab magnetic zog. Yog tias tsis yog hlau nplaum tseem ceeb, lees paub nrog koj tus neeg xa khoom lossis kuaj cov khoom ncaj qha.
