Ntau tus neeg tsis nkag siab tias vim li cas cov hlau tsis muaj steel cua sov raj xeb? Cov laj thawj tuaj yeem yog cov hauv qab no:
1. Thawj qhov ua tau yog tias cov chaw tsim khoom siv stainless hlau 201 los ua txuj ua stainless hlau 304 ua ib qho hluav taws xob cua sov raj; stainless hlau 201 yuav ua rau xeb vim nws cov ntsiab lus nickel sib txawv.
2. Yog hais tias nws yog tiag tiag ua los ntawm stainless hlau 304, nws yuav piav raws li nram no:
Stainless hlau yuav tsis xeb nyob rau hauv ib txwm muaj xwm txheej, tab sis thaum raug cov tshuaj chlorine los yog hnyav ib puag ncig, tshwj xeeb tshaj yog thaum cov passivation txheej ntawm nws nto yog mechanically los yog chemically puas, nws yuav xeb yooj yim dua li niaj zaus, yog li nyob rau hauv no ib puag ncig nws yog yooj yim rau xeb. Qhov saum npoo ntawm cov khoom siv stainless hlau peb feem ntau siv yog passivated, thiab lub thickness ntawm cov chromium oxide zaj duab xis ntawm qhov chaw yog ntau thicker thiab denser tshaj li lub ntuj oxide zaj duab xis tsim rau ntawm qhov chaw tshiab. Yog li ntawd, stainless hlau cua sov raj yuav kuj xeb.

Stainless hlau yeeb nkab yog cov yeeb nkab steel uas tsis tsim xeb hauv qhov chaw, dej tshiab thiab lwm qhov chaw tsis muaj zog corrosive, thiab cov ntsiab lus chromium hauv cov hlau yuav tsum yog ≥12%. Yog tias cov ntsiab lus chromium tsawg lossis tsis siv rau hauv qhov chaw tsis muaj zog corrosive xws li huab cua (xws li nyob rau hauv ib qho chaw tsis muaj zog corrosive xws li cua, tab sis nyob rau hauv cov xwm txheej ntawm lub zos enrichment thiab concentration ntawm Cl-), xeb yuav tshwm sim. Acid-resistant steel yeeb nkab yog cov yeeb nkab steel uas tiv taus corrosion nyob rau hauv acid, alkali, ntsev thiab lwm yam muaj zog corrosive media, tab sis nws kuj yog resistant rau corrosion nyob rau hauv tej yam kev mob, xws li nruab nrab hom, kub, concentration, impurity cov ntsiab lus, ntws. tus nqi, siab, thiab lwm yam rau qee lub sijhawm. Tsis muaj stainless hlau yeeb nkab nyob rau hauv lub ntiaj teb no uas tsis xeb thiab corrosion-resistant nyob rau hauv tej yam kev mob.
Yog li ntawd, txhawm rau xyuas kom meej tias cov hlau saum npoo yog qhov kaj mus tas li thiab tsis corroded, peb pom zoo:
1. Qhov saum npoo ntawm cov hniav stainless hlau yuav tsum tau muab ntxuav thiab txhuam tsis tu ncua kom tshem tawm cov ntawv txuas thiab tshem tawm cov khoom siv sab nraud uas ua rau muaj kev hloov kho.
2. 316 stainless hlau yuav tsum tau siv nyob rau hauv seaside cheeb tsam, 316 khoom yuav tiv taus seawater corrosion.
3. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm qee cov kav hlau stainless hauv kev ua lag luam tsis tuaj yeem ua tau raws li cov qauv sib xws thiab tsis tuaj yeem ua tau raws li cov khoom siv ntawm 304. Yog li ntawd, xeb kuj yuav tshwm sim, uas yuav tsum tau ua tib zoo xaiv cov khoom los ntawm cov tuam txhab muaj npe nrov.
