ASTM A815 UNS S31803 (2205 Duplex / F51) pipe fittings are wrought duplex stainless steel pipe connectors fully compliant with ASTM A815/A815M standard for forged seamless & welded pipe fittings.
UNS S31803 is a balanced ferritic-austenitic dual-phase alloy (50% ferrite + 50% austenite), also called 2205 duplex steel, widely used in chloride-rich harsh industrial piping systems.
Common types: 90°/45° elbow, tee, reducer, cap, stub end, flange, cross, concentric/eccentric reducer.
| Element | Content Limit |
|---|---|
| C | ≤0.030 |
| Mn | ≤2.00 |
| Si | ≤1.00 |
| P | ≤0.030 |
| S | ≤0.020 |
| Cr | 21.0–23.0 |
| Ni | 4.5–6.5 |
| Mo | 2.5–3.5 |
| N | 0.08–0.20 |
| Fe | Balance |
PREN value: 32–35, superior chloride corrosion resistance vs 316L
Raw duplex steel pipe/forging blank inspection → hot forming (press/forging/bending) → trimming & machining → solution annealing (1020–1100℃, rapid water quenching to avoid brittle phase) → pickling & passivation → dimensional tolerance inspection → NDT test (eddy current, hydrostatic, UT) → ferrite content metallurgy test → marking, MTC certification, export moisture-proof packaging
Custom OD, wall thickness, length; polished surface, customized special non-standard fittings per drawing
Supply EN10204 3.1 / 3.2 MTC test reports, PMI composition test, NDT certificates, NACE/NORSOK supporting documents
Full batch traceable by heat number; free replacement for unqualified dimension, metallurgy or corrosion performance within 7 days after receipt
15–25 days for customized forged duplex pipe fittings

S31803 is the original UNS grade, S32205 is upgraded 2205 duplex; most factory materials meet both standards for dual certification, with identical performance in engineering application.
316L fails quickly in high-chloride seawater/sour gas; S31803 has 2x yield strength and far better resistance to pitting & stress corrosion cracking.
Must conduct full solution annealing + rapid water cooling after forming; slow cooling will precipitate σ brittle phase and sharply reduce corrosion resistance & toughness.
Use matching duplex welding wire, full argon shielding for weld root; control interpass temperature below 150℃ to maintain balanced dual-phase microstructure.
