1. Lus Txhais: Dab tsi yog Austenitic Stainless Hlau?

Austenitic stainless hlau yog ib qeb ntawm stainless hlau txhais los ntawm nwsntsej muag-centered cubic (FCC) siv lead ua qauv, lub npe hu uaaustenite theem. Cov qauv no ruaj khov ntawm txhua qhov kub thiab khaws cia txawm tias tom qab txias los ntawm qhov kub thiab txias.

Austenitic stainless hlau yognon-magnetic nyob rau hauv lub annealed mob, muajsiab chromium (16-26%)thiabnpib tsib xee (6-22%)cov ntsiab lus, thiab muabsuperior corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv kev sib piv rau lwm yam stainless hlau tsev neeg.

2. Tshuaj muaj pes tsawg leeg

Cov khoom tshwj xeeb ntawm austenitic stainless hlau los ntawm nws cov tshuaj pleev ib ce:

• Chromium: Muab kev tiv thaiv corrosion thiab tsim cov txheej txheem oxide tiv thaiv ntawm qhov chaw.

• Nickel: Stabilizes austenitic qauv thiab txhim kho ductility.

• Molybdenum (yeem): Txhim kho kev tiv thaiv pitting thiab crevice corrosion nyob rau hauv ib puag ncig chloride.

• Nitrogen: Txhim khu lub zog thiab corrosion kuj.

• Carbon (tsawg heev): Tswj kom tsis txhob carbide nag lossis daus thiab tswj kev tiv thaiv corrosion.

Cov qib zoo li 304 thiab 316 stainless hlau yog ib feem ntawm pawg no.

3. Cov yam ntxwv tseem ceeb ntawm Austenitic Stainless Steel

1. Zoo heev Corrosion Resistance

Austenitic stainless hlau yog cov resistant rau ntau yam corrosive ib puag ncig. Qhov no suav nrog atmospheric corrosion, zaub mov thiab dej haus raug, thiab tshuaj me me mus rau nruab nrab aggressive chemicals.

2. Tsis-Magnetic Properties

Nyob rau hauv cov xwm txheej annealed, austenitic stainless hlau feem ntau tsis yog hlau nplaum. Txawm li cas los xij, kev ua haujlwm txias tuaj yeem qhia me ntsis hlau nplaum vim qhov tsim ntawm martensite.

3. Weldability zoo

Cov hlau no tuaj yeem yooj yim welded siv feem ntau cov txheej txheem vuam. Tej zaum yuav xav tau kev saib xyuas tshwj xeeb kom tsis txhob muaj nag lossis daus ntawm carbide hauv qee qib.

4. High Ductility thiab Toughness

Austenitic qib tuaj yeem kos, khoov, thiab tsim ua ntau yam duab yam tsis muaj kev tawg. Lawv khaws cov tawv nqaij ntawm qhov kub thiab txias.

5. Tsis muaj cua sov Hardening

Tsis zoo li martensitic stainless hlau, qib austenitic tsis tuaj yeem hardened los ntawm kev kho cua sov. Lawv feem ntau hardened los ntawm kev ua haujlwm txias.

4. Common Qib ntawm Austenitic Stainless Steel

• 304 (UAS S30400)
  Feem ntau siv stainless hlau. Zoo heev corrosion kuj, zoo formability, haum rau ntau industries.

• 316 (UAS S31600)
  Muaj molybdenum rau txhim kho corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv chloride ib puag ncig zoo li marine los yog ntug hiav txwv daim ntaub ntawv.

• 310 (NWS S31000)
  Kev kub siab ua haujlwm, siv rau hauv qhov cub thiab cov khoom siv hluav taws xob.

• 321 (NWS S32100)
  Stabilized nrog titanium, zoo tagnrho rau high-kub daim ntaub ntawv uas carbide nag lossis daus yog ib qho kev txhawj xeeb.

Txhua qib no muaj nyob rau hauv ntau hom ntawv xws li nplooj ntawv, kav dej, tuav, thiab fittings, thiab tuaj yeem muab los ntawmsakysteel uarau koj qhov project xav tau.

5. Kev siv ntawm Austenitic Stainless Steel

Ua tsaug rau lawv cov khoom sib npaug, austenitic stainless hlau yog siv rau hauv ntau qhov chaw:

1. Kev lag luam zaub mov thiab dej haus

304 thiab 316 feem ntau yog siv rau cov khoom siv ua zaub mov, tso tsheb hlau luam, thiab cov tais diav vim lawv txoj kev nyiam huv thiab kev tiv thaiv corrosion.

2. Kev Lag Luam Tshuaj thiab Pharmaceutical

316L yog haum rau reactors, kav, thiab li qub raug tshuaj lom neeg vim nws superior tsis kam rau chlorides.

3. Cov cuab yeej kho mob thiab phais

Vim lawv qhov huv thiab biocompatibility, austenitic stainless hlau yog siv rau cov cuab yeej phais, implants, thiab cov khoom siv hauv tsev kho mob.

4. Architecture thiab kev tsim kho

Siv rau hauv cladding, handrails, facades, thiab txuas hniav vim kev zoo nkauj thiab tsis kam mus rau ib puag ncig corrosion.

5. Automotive thiab Tsheb thauj mus los

Exhaust systems, trim, thiab structural Cheebtsam tau txais txiaj ntsig los ntawm kev sib xyaw ntawm lub zog thiab kev tiv thaiv corrosion.

6. Kub Exchangers thiab Boilers

Cov qib siab dua li 310 yog siv nyob rau hauv qhov chaw kub kub vim lawv cov oxidation tsis kam.
