### 1. Dab tsi yog qhov sib txawv ntawm cov kav hlau stainless hlau?
Cov kav hlau hlau stainless hlau tau categorized hauv ntau txoj kev:
* ** LOS NTAWM KEV UA HAUJ LWM
* ** Los ntawm cov duab: ** Cov yeeb nkab feem ntau yog ** cov yeeb nkab hloov tshiab ** (rau cov yeeb yaj kiab uas muag) thiab **
* ** Los ntawm kev ua tiav: ** Pipes tuaj nrog ntau qhov chaw ua tiav zoo li **
### 2. Vim li cas tsis muaj hlau siv rau kav dej?
Qhov no yog qhov tsis meej. Stainless hlau ** yog feem ntau siv rau cov kav dej ** Hauv ntau hom kev lag luam. Txawm li cas los xij, nws tsis yog siv rau txhua daim ntawv thov xwb vim tias:
* ** Tus nqi: ** Tus kav hlau tsis tshua kim dua carbon steel lossis pipes yas (zoo li luam tawm cov kab uas yog xeb tsis yog qhov teeb meem loj.
* ** Lub zog - - Qhov hnyav, qee cov pa roj carbon monoxide}} Cov pa roj carbon monoxide}} Cov pa roj carbon monoxide}} Cov pa roj carbon monoxide
* ** Lub thermal conductivity: ** Nws muaj qis dua thermal conductivity tshaj tooj liab, yog li nws tsis yog thawj qhov kev xaiv rau cov cua sov ua kom hloov cua sov ua ntej.
### 3. Peb lub ntsiab ntawm cov hlau tsis muaj dab tsi?
The three primary types of stainless steel, based on their crystalline microstructure, are:
* ** ASTUSTENITIC (piv txwv li, 304, 316): ** Feem ntau hom; Tsis -} sib nqus, zoo heev corrosion tsis kam, thiab muaj heev. Siv hauv chav ua noj, cov khoom siv tshuaj lom neeg, thiab cov khoom siv architectural.
* ** Ferritic (piv txwv li, 430): ** Sib nqus, nrog zoo corrosion tsis kam tab sis tsawg dua li Austenitic. Nws muaj cov chromium siab tab sis cov ntsiab lus muaj roj carbon tsawg. Feem ntau siv hauv kev txiav tsheb thiab cov ntawv thov kev lag luam.
* ** MARTENSITIC (piv txwv li, 410, 420): ** Sib nqus, tuaj yeem sib nqus los ntawm kev kho cua sov, thiab muab lub zog siab. Txawm li cas los xij, nws muaj qis dua corrosion tsis kam. Siv rau riam, turbine hniav, thiab cov tshuab kho tshuab.
### 4. Yuav ua li cas paub yog tias cov yeeb nkab yog hlau hlau?
Ntawm no yog ob peb txoj kev yooj yim los txheeb xyuas cov yeeb nkab steel hlau:
* ** Saib xyuas kev pom: ** Saib rau tus du, silvery - grey grey nto uas feem ntau ci me ntsis. Nws yuav tsum tsis muaj ib qho cim ntawm xim liab (nws tuaj yeem tau txais cov qij lossis "tshuaj yej -}}}, tab sis tsis flaky xeb).
* ** MOTERET TEST: ** Siv cov hlau nplaum muaj zog. Austenitic stainless hlau (zoo li 304) feem ntau tsis-} sib nqus lossis sib nqus me ntsis. Yog tias cov hlau nplaum tsis lo ua ke, nws yog feem ntau yog ib qho kev kawm nquag ntawm stainless. Yog tias nws tau ruaj khov, nws tuaj yeem yog qib sib txawv ntawm cov hlau uas tsis tu ncua lossis niaj zaus.
* ** Kev ntsuas txim (rau cov neeg siv kev paub): ** Sib tsoo cov hlau ua rau lub txim taws. Stainless hlau ua luv luv, straw -} xim ci ntsa iab. Pa roj carbon steel tsim ntev, dawb - sparks daj nrog ntau dua "tawg." Txoj kev no yuav tsum muaj kev xyaum.
* ** Txheeb xyuas rau cov cim / cov cim: ** Ntau cov kav dej muaj nyiaj muas, lossis cov cim xim, lossis cov cim kob uas qhia cov khoom qib (piv txwv li, "SS304," "" 316SS ").
### 5. Yuav ua li cas los txheeb xyuas steel vs stainless hlau?
Qhov yooj yim thiab tshaj plaws txhim khu kev qha rau qhov tsis - kws tshaj lij los qhia qhov sib txawv yog:
* ** Qhov kev xeem magnet: ** Qhov no yog tus paub tseem ceeb. ** Cov hlau tsis tu ncua (carbon hlau) ** yog ** sib nqus ** sib nqus **; Hlau nplaum yuav lo rau nws heev khov kho. ** Ntau hom stainless hlau (Austenitic) ** Yog ** tsis sib nqus ** lossis tsuas yog sib nqus me ntsis; Hlau nplaum yuav tsis lo zoo los yog txhua.
* ** Rust kuaj: ** Rub cov ntaub ntub dej ntawm cov hlau thiab tawm nws rau 24 teev. ** Cov hlau tsis tu ncua yuav tsim cov xeb liab tsw ntev ** sai sai. ** Stainless hlau yuav tsis xeb **; Nws tuaj yeem tsim cov me nyuam dej, tab sis lawv yuav so tseg yam tsis muaj pitting lossis xeb.
* ** Lub zog pom: ** Stainless hlau feem ntau muaj qhov ci ntsa iab, ntau dua li sib xws, thiab smoother "silvery" saib. Cov hlau tsis tu ncua feem ntau muaj tsaus nti, cov xim txho xim thiab tej zaum yuav muaj xim dub lossis txawm tias xeb.
