Cov qhab nia xaiv tau
- Rau cov dej txias ib puag ncig nrog cov ntsiab lus chloride tsawg, 316L stainless hlau yog qhov kev xaiv tsim nyog; nws yog tus nqi ntau dua - zoo thiab yooj yim rau fabricate dua duplex stainless hlau.
- Rau sulfuric acid ib puag ncig thiab cov khoom siv tshuaj, 904L stainless hlau yog ib qho kev xaiv; nws muaj kev tiv thaiv corrosion zoo heev, txawm tias nws muaj cov khoom siv ntau dua thiab qis zog dua li duplex stainless hlau.
- Rau ib puag ncig corrosive heev, Nickel Alloy 625 tuaj yeem xaiv tau; nws muaj superior corrosion kuj rau duplex stainless hlau tab sis ntawm tus nqi siab heev.

FAQ
Q: Qhov txawv ntawm S31803 thiab S32205 yog dab tsi, thiab vim li cas S32205 tam sim no nyiam?
A: S32205 nce qhov tsawg kawg nkaus nitrogen cov ntsiab lus mus rau 0.14%, ua kom muaj kev ruaj ntseg txaus austenite nyob rau hauv vuam kub- cuam tshuam cheeb tsam (HAZ) thiab tiv thaiv qhov poob ntawm corrosion kuj. Yog li ntawd, nws tau hloov tag nrho S31803 raws li tus qauv qib rau 2205 duplex stainless hlau.
Q: Duplex stainless hlau kav puas tuaj yeem siv ncaj qha rau dej hiav txwv txias?
A: Yog. S32205 yog haum rau qis- kub, ntws dej hiav txwv daim ntaub ntawv, whereas S32750 yog zoo dua haum rau sov, nyob twj ywm, los yog muaj kuab paug seawater ib puag ncig.
Q: Koj puas muab U- raj, thiab qhov tsawg kawg yog dabtsi yog khoov vojvoog?
A: Yog lawm, peb muab U- raj uas ua raws TEMA thiab HEI cov qauv. Qhov tsawg kawg nkaus dabtsi yog khoov vojvoog yog feem ntau txhais raws li ib tug centerline vojvoog ntawm yam tsawg kawg yog 1.5 npaug ntawm lub cheeb txoj kab uas hla; Txawm li cas los xij, qhov no tuaj yeem ua kom zoo raws li cov khoom siv thiab cov phab ntsa tuab kom tiv thaiv kev tawg thiab cov phab ntsa ntau dhau.
