1. ** Koj puas tuaj yeem ua kev puas tsuaj stainless hlau? **
* ** Yog, Stainless hlau yuav raug puas ntsoog. ** Thaum nws muaj kev tiv thaiv kev xeb thiab staining, nws tuaj yeem raug khawb, txhuam, los yog khoov, lossis bouschically. Nws tseem tuaj yeem corrode raws cov mob tshwj xeeb zoo li raug rau cov chlorides muaj zog (piv txwv li, tshuaj muaj ntshav, acids, lossis kub heev. Ntev ntev li cas rau ib puag ncig kev npau taws no tuaj yeem ua rau pitting, crevice corrosion, lossis kev ntxhov siab corrosion tawg.
2. ** Koj puas tuaj yeem tawm ntawm cov hlau stainless hauv nag? **
* ** Yog, Stainless hlau feem ntau yuav tsum tau sab laug hauv cov nag. ** Lub passive chromium oxide txheej tiv thaiv cov hlau. Txawm li cas los xij, nyob rau hauv cov chaw muaj kuab paug ib puag ncig lossis cov ntug dej hiav txwv nrog cov dej qab zib, tuaj yeem ntxuav cov tsis huv mus rau qhov kev pheej hmoo ntawm corrosion dhau sijhawm.
3. ** Ntev npaum li cas yuav stainless hlau kawg nyob rau hauv dej? **
* ** Stainless hlau yuav kav ntev li kaum tawm hauv qab, nyob ntawm cov qib, thiab txhua yam. ** Siv dej hiav txwv uas muaj kev siv hauv dej hiav txwv thiab muaj kev vam meej. Hauv dej tshiab, cov qib kawm (zoo li 304) tuaj yeem ntev heev. Yam xws li dej kub, salinege, cov ntsiab lus pa, cov pa phem, thiab muaj qhov cuam tshuam ntau ntxiv rau kev siv sia. Tsim nyog xaiv cov qauv thiab tsim (zam kev nkhaus / stagnation) yog qhov tseem ceeb rau lub neej dej siab tshaj plaws. Cathodic kev tiv thaiv yog qee zaum siv rau hauv kev txhoj puab heev.
4. ** Muaj peev xwm tuaj yeem tso cov hlau sab nraud? **
* ** Yog, Stainless hlau yog zoo heev rau kev xaiv sab nraum zoov. ** Nws muaj kev xaiv sab nraum zoov ua rau corrosion ua rau nws cov kev sib tw, facades, sculptures, thiab rooj tog sculptures, thiab sab nraum zoov rooj tog. Cov qib nyiam li 304 (dav dav sab nraum zoov) thiab 316 (Nqis / Nqis Kev Lag Luam) feem ntau siv. Qhov tsim nyog xaiv rau ib puag ncig tshwj xeeb (tshwj xeeb yog qhov chaw tshwj xeeb rau dej ntsev) thiab qee zaus ntxuav (kom tshem tawm cov av qias neeg (kom tshem tawm cov kuab paug, los yog ua kom pom tseeb nws qhov tsos.
5. ** Dab tsi kub yuav puas steel hlau? **
* Stainless hlau puas puas los ntawm ** ntau heev kub heev **, feem ntau los ntawm ** oxidation (scaling (scaling) ** thiab poob ntawm lub zog. Qhov ntsuas kub thiab txias yog muaj ntau rau qib tshwj xeeb:
* ** COV KEV PAB CUAM: ** Feem ntau cov qib (304, 316) tuaj yeem siv nyob ib ncig ntawm ** 870℃(1600℃f) ** ua ntej ntsuas kev ntsuas loj. Cov qhab nia siab dua (zoo li 310) tiv thaiv txog ** 1150℃(2100℃f) **.
* ** Kev pabcuam sib txawv: ** Lawv tuaj yeem tiv taus ntau dua qhov ntsuas kub tshaj plaws.
* ** Tus qauv ua kom puas tsuaj: ** Qhov ** melting point ** yog ib ncig ** 1400-1450℃(2550-2640℃f) ** rau Austenic qib (304, 316).
* ** Lwm yam kev puas tsuaj: ** Kev hloov kub sai sai tuaj yeem ua rau thermal poob siab. Raug rau qhov kub thiab txias * ua ke * nrog cov ntsev lossis cov txiv neej ua kom nrawm dua (piv txwv li kub) tsawg dua (45000-950℃f). Tsis tshua muaj kub feem ntau tsis ua kev puas tsuaj rau kev puas tsuaj hlau, ua rau nws haum rau kev siv cryogenic siv.
