Cov phaj stainless hlau muaj lub ntsej muag du, siab yas, muaj lub zog tawv thiab cov tshuab muaj zog, thiab muaj kev tiv thaiv kom tsis txhob xeb los ntawm cov kua qaub, alkaline roj, kev daws teeb meem thiab lwm yam tshaj tawm. Nws yog cov hlau tsis muaj steel uas tsis yooj yim rau xeb, tab sis nws tsis yog kiag li xeb-dawb.
Kev tiv thaiv corrosion ntawm stainless hlau mas nyob ntawm nws cov khoom sib xyaw ua ke (chromium, npib tsib xee, titanium, silicon, txhuas, thiab lwm yam) thiab cov qauv sab hauv, thiab lub luag haujlwm tseem ceeb yog chromium. Chromium muaj cov tshuaj ua kom muaj lub zog ruaj khov thiab tuaj yeem tsim zaj duab xis passivation nyob rau saum npoo ntawm cov hlau kom cais cov hlau ntawm lub ntiaj teb sab nraud, tiv thaiv lub phaj steel los ntawm oxidation, thiab nce qhov corrosion kuj ntawm steel phaj. Tom qab zaj duab xis passivation tau rhuav tshem, kev txhim kho corrosion tsawg.
Nws yog qhov yuav tsum muaj peev xwm tiv taus qhov corrosion ntawm ntau cov acids xws li oxalic acid, sulfuric acid-iron sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-tooj liab sulfate, phosphoric acid, formic acid, acetic acid, etc. Nws yog dav siv hauv kev siv tshuaj, khoom noj, tshuaj, papermaking, roj av, atomic zog, thiab lwm yam Kev lag luam, nrog rau ntau qhov chaw thiab cov khoom siv ntawm kev tsim kho, chav ua noj, khoom siv tais diav, tsheb, thiab khoom siv hauv tsev. Txhawm rau kom ntseeg tau tias qhov tawm ntawm lub zog, tensile lub zog, elongation thiab hardness ntawm ntau yam steel hlau daim hlau ua tau raws li cov kev xav tau, cov hlau steel hlau yuav tsum yauv tsis pom zoo, kev kho tshuaj, kev laus thiab lwm yam kev kho cua sov ua ntej xa khoom
