** 1. Dab tsi yog 403 steel? **
403 stainless hlau yog martensitic stainless hlau. Nws cov yam ntxwv tseem ceeb yog tias nws tuaj yeem ua tau nyuaj los ntawm kev kho cua sov. Nws yog kev hloov kho ntawm 510 qib, nrog ntxiv rau cov titanium los txo kev loj hlob carbide thaum vuam thiab kho cua sov. Qhov no ua rau nws haum ntau rau cov ntawv thov zoo li cov tshuab lim dej, thiab cov li qub uas yog qhov zoo tshaj plaws yog xav tau.
** 2. Dab tsi yog 3310 steel? **
3310 tsis yog tus qauv stainless hlau tsim zoo li cov neeg ntawm AISI (piv txwv li, 304, 316). Nws yog feem ntau yuav yog lub npe ntawm cov tswv lossis lub npe luam tawm rau hom hlau tshwj xeeb, tej zaum yog lub peev txheej siab lossis} lub zog alloyoy. Yog tsis muaj cov ntsiab lus ntxiv los ntawm cov khoom muag, nws muaj pes tsawg leeg thiab cov khoom yog qhov nyuaj los txhais. Nws tsis yog ib qho qib ib txwm nyiam lwm tus koj tau hais tseg.
** 3. Dab tsi yog 501 steel? **
Zoo ib yam li 3310, "501" tsis yog tus qauv AISI stainless hlau. Nws tuaj yeem siv tau cov pa roj carbon lossis ib co hlau los ntawm cov qauv sib txawv (zoo li cov qauv Askiv), tab sis nws tsis yog tus lej ntawm cov hlau tsis muaj tseeb. Nws yog ib qho tseem ceeb kom kuaj cov ntaub ntawv pov thawj lossis lub hauv paus ntawm lub npe no rau cov ntaub ntawv raug.
** 4. Puas yog A2 hlau tib yam li 304? **
Tsis yog, lawv sib txawv kiag li. Qhov no yog ib qho tshwm sim ntawm kev tsis meej pem.
* ** A2 hlau ** yog hais txog qib ntawm * Tuam Hlau Hlau * Paub Txog Qhov Zoo Zog Thiab Cov Quav Zoo Tshaj Kuj. Nws yog huab cua - tawv ("ib qho" sawv ntsug rau huab cua) thiab feem ntau yog siv rau kev ua cov cuab yeej, tuag, thiab gauges.
* ** 304 Hlau ** Hais txog cov qhab nia feem ntau ntawm * Austenitic Stainless Hlau *. Nws tsis yog qhov nyuaj los ntawm kev kho cua sov thiab muaj npe nrov rau nws cov zoo heev corrosion tsis kam thiab muaj peev xwm. Nws yog siv rau cov khoom vaj tse ua noj, cov khoom siv tshuaj lom neeg, vaj tse vaj tse, thiab ua khoom noj khoom haus khoom noj.
Hauv cov ntsiab lus: A2 yog ib qho nyuaj, tawv roj hlau; 304 yog qhov muag muag, corrosion - Tsis kam ua cov hlau tsis tshua muaj.
** 5. Kuv tuaj yeem qhia tau li cas yog tias kuv tus hlau stainless yog 304 lossis 202? **
Paub qhov txawv ntawm 304 thiab 202 visually yog qhov nyuaj heev vim tias lawv saib zoo li zoo tib yam. Koj yuav tsum tau ua qee qhov kev ntsuam xyuas yooj yim:
* ** Qhov ntsuas sib nqus: ** Qhov no yog qhov yooj yim tshaj plaws thawj kauj ruam. Lob lub zog loj hlau nplaum. Austenitic stainless hlau xws li 304 thiab 202 feem ntau tsis-} sib nqus lossis tsuas yog sib nqus me ntsis. Txawm li cas los xij, 202 muaj cov ntsiab lus manganese ntau dua, uas tuaj yeem ua rau nws muaj qhov tsis muaj zog ntawm cov lus teb, thaum 304 yog yuav luag txhua lub sijhawm tsis yog- sib nqus. Yog tias cov hlau nplaum uas muaj zog heev, nws yog tsis yog 304 lossis 202.
* ** Qhov kev sim tshuaj lom neeg (kev sim siab): ** Qhov no yuav tsum muaj kev paub thiab kev ceev faj kev nyab xeeb. Sib tsoo cov hlau yuav tsim cov txim taws. 304 (ntau dua "tawg tau ntau dua 304, tab sis qhov sib txawv me ntsis thiab nyuaj rau cov novice kom pom.
* ** Kev sim tshuaj (tee ntsuas): ** Feem ntau ntseeg tau txoj kev rau qhov tsis {{kws tshaj lij yog siv cov tshuaj sim. Koj tuaj yeem yuav cov khoom "tso tawm" cov khoom siv rau cov hlau stainless. Koj tso ib qho kev poob ntawm kev ntsuas ntsuas ntawm cov hlau huv. Cov xim hloov tom qab qee lub sijhawm yuav qhia txog cov ntsiab lus ntsig txog tsib xee,}}}- nas 304.
Rau cov lus teb meej, kev tsom xam cov ntaub ntawv (zoo li XRF spectrometry) yog tib txoj kev. Rau feem ntau cov hom phiaj ua tau, kev sib xyaw ntawm cov hlau nplaum xeem thiab kev ntsuas tshuaj lom neeg yuav ua rau koj pom zoo heev.
