Corrosion Performance: Dab tsi 316L tiag tiag muab rau koj
Pitting Resistance (ASTM G48 Txoj Kev A)
ASTM G48 qhov tseem ceeb pitting kub (CPT) ntsuas yog qhov ua tau zoo los sib piv cov qib stainless hauv kev pabcuam chloride:
| Qib | PREN | CPT (degree) hauv 6% FeCl₃ | Seawater Pitting Index |
|---|---|---|---|
| 304 / 1.4301 | 18 | 15-20 | Txwv tsis pub |
| 316 / 1.4401 | 24 | 25-30 | Nruab nrab |
| 316L / 1.4404 | 24 | 25-30 | Nruab nrab |
| 904L / 1.4539 | 35 | 45-50 | Zoo |
| 254 SMO / 1.4547 PAB | 43 | 60-70 | Zoo heev |
| Duplex 2205 / 1.4462 | 35 | 45-55 | Zoo |
| Super duplex 2507 / 1.4410 | 42 | 70-80 | Zoo heev |
316L tau txais kev zoo li qub thiab qeeb - txav dej hiav txwv mus txog 25℃. Saum toj no 25 degree, nyob rau hauv chlorinated dej txias, los yog nyob rau hauv lub tshuab nrog biofouling, 316L pib mus rau hauv lub qhov thiab txoj kev upgrade yog duplex 2205 → super duplex 2507 → 254 SMO.
Crevice Corrosion
Cov dej hiav txwv thiab cov tshuaj chloride-cov txheej txheem cov kua dej ua rau muaj kev xeb ntawm lub ntsej muag flange, gasket grooves, thiab nyob rau hauv cov deposits ua ntej lawv ua rau pitting dav . 316L tuav crevice corrosion roughly 50% zoo dua li 304 tab sis tseem muaj kev pheej hmoo qis dua li 15℃hauv kev pabcuam tsis ruaj khov.
Sour Service (NACE MR0175 / ISO 15156 Part 3)
316L hauv cov tshuaj-annealed mob tau pom zoo rau kev pabcuam qaub raws li NACE MR0175 / ISO 15156 Ntu 3, nrog rau cov kev txwv no:
- Hardness Tsawg dua los yog sib npaug rau 22 HRC
- Ua haujlwm txias qis dua 5% (tsis muaj kev sib sau hnyav)
- Siv hauv chloride-dawb lossis qis-chloride H2S ib puag ncig ib tus qauv
Rau saum toj no -22-HRC lossis hnyav hnyav- cov ntawv thov ua haujlwm - suav nrog qee qhov txias- kos cov raj xa dej nrawm - cov khoom ntog sab nraum NACE MR0175 hauv nws cov khoom tsim thiab tej zaum yuav xav tau kev ntxhov siab lossis lwm yam kev tsim nyog.
- Rau siab dua -siab / siab dua-kub qaub kev pab cuam, nce mus rau:
- Duplex 2205 los yog super duplex 2507 rau chloride + H2S ua ke
- Inconel 625, Inconel 825 rau siab dua H2S ib nrab siab thiab kub
- Hastelloy C276 rau hnyav qaub + chloride kev pabcuam
