Kev xaiv cov khoom siv flange stainless hlau yuav tsum yog raws li kev ntsuam xyuas tag nrho ntawm qhov xwm txheej ntawm daim ntawv thov, qhov chaw corrosive, kub, siab, thiab lwm yam mob. Hauv qab no yog cov ntaub ntawv siv thiab lawv cov xwm txheej siv tau:
304 Cov Hlau Tsis Xeb (06Cr19Ni10)
Nta: Muaj 18% chromium thiab 8% nickel, tsis muaj molybdenum, tiv taus kev xeb dav dav, tsim nyog tus nqi.
Cov xwm txheej siv tau: Ib puag ncig qhuav, kev ua zaub mov, kev kho kom zoo nkauj, cov khoom siv hauv tsev, thiab lwm yam.
Cov Kev Txwv: Yooj yim rau kev xeb hauv cov chaw uas muaj chloride ions (piv txwv li, dej hiav txwv, dej pas dej ua ke).
316 Cov Hlau Tsis Xeb (06Cr17Ni12Mo2)
Nta: Muaj 2.5% molybdenum, txhim kho kev tiv thaiv rau chloride ion corrosion, kub siab tiv taus (≤649 ℃).
Cov xwm txheej siv tau: Cov khoom siv hauv dej hiav txwv, cov kav dej tshuaj, cov cuab yeej kho mob, qhov kub thiab txias thiab qhov siab.
304L/316L (Cov Qauv Uas Muaj Carbon Tsawg)
Nta: Cov ntsiab lus carbon ≤0.03%, zoo dua tiv taus kev xeb intergranular piv rau tus qauv 304/316.
Cov xwm txheej siv tau: Cov khoom siv raug vuam kub siab lossis xav tau kev tiv thaiv xeb mus sij hawm ntev (piv txwv li, lub zog nuclear, tshuaj).
Lwm Cov Khoom Siv
347 Stainless Steel (CF8C): Muaj niobium, tsim nyog rau qhov kub thiab txias heev (≥540 ℃).
Duplex Stainless Steel: Ua ke cov khoom austenitic thiab ferritic, muaj zog dua, tsim nyog rau dej hiav txwv tob lossis cov xwm txheej siab.
Cov Lus Qhia Txog Kev Xaiv
Kev Siv Hauv Kev Lag Luam Dav Dav: Nyiam 304, pheej yig thiab ua tau raws li feem ntau cov kev xav tau.
Ib puag ncig xeb: Xaiv 316 lossis 316L, molybdenum zoo tiv taus chloride ion corrosion.
Cov Chaw Kub/Nyuaj Siab Tshwj Xeeb: Xaiv cov khoom siv uas muaj cov pa roj carbon tsawg lossis cov khoom siv duplex raws li qhov kub thiab txias uas tau teev tseg.
