Stainless hlau tsis yooj yim rau xeb, tab sis kuj tuaj yeem xeb. Qhov laj thawj yog vim li cas stainless hlau tsis yooj yim rau xeb muaj ntau yam ua rau cov hlau tsis muaj hlau. Ntxiv nrog rau cov hlau, stainless hlau kuj muaj chromium, npib tsib xee, txhuas, silicon, thiab lwm yam. Cov ntsiab lus chromium ntawm cov hlau stainless feem ntau tsis tsawg dua 12%, thiab qhov siab tshaj plaws yog 18%. Tom qab ntxiv chromium thiab lwm yam khoom rau hlau, cov khoom ntawm cov hlau tuaj yeem hloov tau. Piv txwv li, cov qauv molecular ntawm cov hlau yog ntau yam sib xws, thiab nws yooj yim dua los tsim cov oxide tiv thaiv zaj duab xis rau saum npoo ntawm cov hlau, yog li txhim kho corrosion kuj ntawm stainless hlau. Yog li ntawd, stainless hlau tuaj yeem tiv taus corrosion ntawm hluav taws, dej, kua qaub, alkali thiab ntau yam kev daws teeb meem, thiab yuav tsis xeb. Cov kws tshawb fawb tau pom tias qhov sib txawv ntawm cov qauv hlau sab hauv, qhov sib ze ntawm ntau yam khoom sib txuas, thiab qhov nyuaj dua nws yog rau cov khoom corrosive invade. Tsis tas li ntawd, ib txheej ntawm oxide tiv thaiv zaj duab xis yog txuas rau saum npoo, ib yam li muab cov cuab yeej rau ntawm cov hlau, yog li nws tsis yooj yim rau xeb.
Vim li cas stainless hlau kuj xeb? Thaum cov xim xim av xeb (dots) tshwm rau saum npoo ntawm cov kav hlau stainless, tib neeg xav tsis thoob: lawv xav tias "stainless hlau tsis xeb, thiab yog tias nws xeb, nws tsis yog stainless hlau, thiab tej zaum yuav muaj qee yam tsis zoo ntawm cov hlau. " Qhov tseeb, qhov no yog ib qho kev pom thiab tsis ncaj ncees ntawm stainless hlau uas tsis muaj kev nkag siab. Stainless hlau kuj yuav xeb nyob rau hauv tej yam kev mob. Stainless hlau muaj peev xwm tiv taus atmospheric oxidation, uas yog, stainlessness, thiab kuj muaj peev xwm tiv thaiv corrosion hauv xov xwm uas muaj acids, alkalis, thiab ntsev, uas yog, corrosion kuj. Txawm li cas los xij, qhov loj ntawm nws cov corrosion kuj txawv nrog cov tshuaj muaj pes tsawg leeg ntawm cov hlau nws tus kheej, lub xeev ntawm kev ntxiv, cov kev siv, thiab hom kev tshaj tawm ib puag ncig. Piv txwv li, 304 steel kav muaj qhov zoo heev corrosion kuj nyob rau hauv qhuav thiab huv si huab cua, tab sis yog hais tias lawv tsiv mus nyob rau hauv ntug hiav txwv dej, lawv yuav sai sai xeb nyob rau hauv hiav txwv pos huab uas muaj ntsev ntau; thaum 316 steel kav ua tau zoo. Yog li ntawd, tsis yog txhua yam ntawm stainless hlau tuaj yeem tiv taus corrosion thiab tsis xeb hauv ib puag ncig.
