Compare Duplex 2205 and Super Duplex 2507 for chloride, marine, desalination, offshore and chemical RFQs.
Duplex 2205 is often reviewed for strength and chloride resistance above standard austenitic stainless grades, while Super Duplex 2507 is reviewed for more demanding chloride, seawater, desalination and offshore conditions. Final selection should follow buyer drawings, standards, service conditions and project requirements.
| Option | Common buyer review context | RFQ note |
|---|---|---|
| Duplex 2205 | Process piping, tanks, heat exchangers and marine-adjacent equipment | Share chloride level and design standard. |
| Super Duplex 2507 | Seawater, desalination, offshore and highly corrosive service | Mention exact standard and inspection needs. |
| Zeron 100 | Project-specified super duplex enquiries | Do not assume equivalence; share exact designation and standard. |

No. Super Duplex 2507 is reviewed for more severe conditions, but Duplex 2205 may be appropriate when the project specification allows it.
It refers to resistance against chloride-driven pitting and crevice corrosion. Buyers should share service media, temperature and chloride level when known.
It may be reviewed for some desalination-related requirements, while Super Duplex or SMO 254 may be specified for severe seawater exposure.
Pipes, plates, flanges, fittings, bars, fasteners and cut-size material are common RFQ forms.
Mention grade, standard, product form, pressure class, size, quantity, documentation and any project inspection requirement.
Share grade, product form, size, quantity, standard, documentation requirements and delivery location for quotation review.
