### 1. Dab tsi yog cov teeb meem uas muaj 304 hlau?
304 Stainless hlau yog ib qho zoo tshaj plaws- hom phiaj qib, tab sis nws muaj ob peb qhov tsis tseem ceeb:
* ** Sensitivity rau Chlorides: ** Nws qhov tsis muaj zog yog qhov nws tau ntxim siab tshaj plaws rau pitting thiab crevice corrosion nyob rau hauv ib puag ncig muaj chlorides. Qhov no txhais tau tias nws muaj peev xwm xeb thaum raug rau Saltwater, De - iching salts, lossis txawm tias muaj kuab tshuaj ntxuav tshuaj, lossis txawm muaj zog tshuaj ntxuav tshuaj.
* ** Kev ntxhov siab corrosion cracking (SCC): ** Raws li cov tshuaj chlorides thiab nyob rau hauv muaj cov tshuaj chlorides thiab kub siab, uas yog qhov tsis muaj phom sij.
* ** TSIS yog rau kev siv marine: ** Nws yog feem ntau tsis pom zoo rau kev siv nyob rau hauv submerged lossis txaws zones hauv cov chaw ua haujlwm marine vim yog cov teeb meem chloride.
* ** QIB COL SOLIGHTANCE tsis kam 45: ** Thaum zoo heev rau cov qhab nia txhua hnub ntau dua 316, ua rau nws tsis zoo rau kev lag luam ntau lossis tshuaj lom neeg.

### 2. Tau 316 stainless hlau xeb?
Yog lawm, ** 316 stainless hlau tuaj yeem xeb nyob rau hauv tshwj xeeb **. Nws yog heev * corrosion - tiv taus *, tsis corrosion {}} * pov thawj *. Qhov feem ntau txoj kev uas nws xeb yog los ntawm:
* ** Kev kis tau rau Chlorides: ** Ntev los yog tas mus li ntawm Chocoride (piv txwv li lub marine kev txaws thaj chaw) tuaj yeem ua rau pitting corrosion.
* ** Yog tias cov khoom sib kis ntom ntom ntom nti Qhov no tsis yog cov hlau nws tus kheej xeb tab sis cov paug tsis huv uas tuaj yeem ntxuav tawm.
* ** Corrosion corrosion: ** Hauv kev nruj me ntsis, txuas cov roj av, lossis tso nyiaj rau cov pa, lossis tso nyiaj tawm tsam cov txheej txheem tiv thaiv, ua rau xeb.

### 3. Cov qib twg ntawm stainless hlau yuav tsis xeb?
** Tsis muaj qib ntawm stainless hlau yog tshem tawm tag nrho rau xeb ** hauv txhua yam xwm txheej. Lo lus "stainless" txhais tau tias nws * stains tsawg dua *, tsis yog tias nws tsis tuaj yeem stain lossis xeb. Txawm li cas los xij, qee qib kawm yog tus tsis kam tiv:
* Qhov feem ntau xeb - Cov qhab nia tsis txaus ntseeg yog cov uas muaj ob theem siab, thiab ib txwm alloy zoo li nitrogen lossis tooj liab.
* Cov qib nyiam xws li ** 316L ** (cov pa roj carbon) ntawm 316) muab cov kev tiv thaiv zoo tshaj plaws rau feem ntau cov kev cov nyom.
* Rau cov pej xeem ntau heev, ** "Super Austenic" ** Qib zoo li ** 904L ** lossis ** 254) ** yog siv. Cov no muaj ntau dua molybdenum thiab chromium cov ntsiab lus rau kev ua rau chlorides thiab cov acids.
* Rau kev ua yeeb yam siv tshuaj, ** "Chav" qib nyiam ** 2205 ** muab lub zog loj thiab ua rau muaj kev ntxhov siab corrosion.
Yog li, thaum tsis muaj qib kawm yog zoo meej, cov siab -}} Ente alloys yuav tsis muaj kob txhua hnub thiab feem ntau muaj kev lag luam ib puag ncig.

### 4. Dab tsi yog qhov tsis zoo ntawm 316 hlau?
Lub ntsiab tseem ceeb ntawm 316 stainless hlau muaj feem cuam tshuam nrog tus nqi thiab kev ua:
* ** Tus nqi them siab dua: ** Nws yog kim dua li 304 stainless hlau vim nws molybdenum thiab siab dua tsib xee cov ntsiab lus. Qhov no tuaj yeem cuam tshuam pob nyiaj ua haujlwm.
* ** Qhov nyuaj tshaj plaws rau lub tshuab: ** Ntxiv rau Molybdenum ua rau cov alloy sauv dua, uas tuaj yeem ua rau cov khoom siv nrawm dua thiab muaj kev nyuaj ntau dua thaum lub tshuab ua haujlwm thiab cov kev tsim hluav taws xob piv rau 304.
* ** TSIS TXHOB SIV: ** Rau ntau lub hauv paus lossis ib puag ncig me me (zoo li chav ua noj tog lossis khoom siv), 304 yog qhov zoo kawg nkaus. Siv 316 nyob rau hauv cov rooj plaub no yog kev siv nyiaj tsis tsim nyog.
* ** Koj tseem tuaj yeem corrode: ** Thaum zoo heev, nws tsis yog qhov ua tsis tau. Nws tseem tuaj yeem raug kev txom nyem los ntawm kev mob corrosion nyob rau hauv kev txhoj puab heev, lub ntsiab lus txawm muaj ntau dua (thiab kim) alloys yuav tsum muaj rau cov ntawv thov no.

### 5. Dab tsi yog lub neej cia siab ntawm 316 stainless hlau?
Tsis muaj ib tus lej rau lub neej kev cia siab ntawm 316 stainless hlau, vim nws nyob ntawm nws ib puag ncig. Txawm li cas los xij, nws tuaj yeem piav qhia raws li nram no:
* ** Hauv cov chaw me me: ** hauv sab hauv tsev, qhuav, lossis cov hlau tsis muaj zog nyob hauv tsev), 316 Stainless) Zoo kawg li **, nrog qhov tsawg kawg nkaus **, nrog tsawg kawg nkaus **, nrog tsawg kawg rau kev xeb.
* ** Nyob rau hauv ib puag ncig hnyav: ** Hauv cov chaw hnyav zoo li cov kab tsuag ntug dej hiav txwv lossis cov khoom siv tau ntev heev tab sis yuav ntsuas tau hauv 4 {{2} {xyoo). Kev tu xyuas kom zoo thiab kev tu kom tshem cov kev tso nyiaj corrosive yog qhov tseem ceeb rau maximizing lifespan ntawm no.
* ** Hauv cov chaw muaj kev lag luam loj lossis lub neej ua kom zoo yuav luv thiab yuav tsum tau ua tib zoo suav nrog cov tshuaj lom neeg tshwj xeeb, ntsuas kub thiab ntxhov siab. Nws tuaj yeem muaj los ntawm ** tsawg dua ib xyoos rau ntau xyoo ** hauv cov neeg mob hnyav.
