Super Duplex Stainless Steel Plate – Alloys S32205, S32750, S32550 – Hot Rolled, 3.0–30.0 mm – Exceptional Corrosion Resistance
Product Overview
We offer premium super duplex stainless steel plates in three high-performance grades:
- UNS S32205 (2205) – Standard Duplex (often grouped with super duplex due to widespread use)
- UNS S32750 (2507) – True Super Duplex
- UNS S32550 (Ferralium® 255) – High-Strength Super Duplex with Copper
Available in thicknesses from 3.0 mm to 30.0 mm, these hot-rolled, solution-annealed plates deliver outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC)—especially in aggressive environments like seawater, chemical processing, offshore oil & gas, and desalination plants.
All plates are manufactured to international standards (ASTM A240, EN 10088-2) and supplied with full mill certification, ensuring reliability for critical applications.
Note: While S32205 is technically a standard duplex, it is frequently included in super duplex discussions due to its superior performance over 300-series austenitics. S32750 and S32550 are true super duplex alloys with PREN ≥ 40.
Key Features
✅ PREN (Pitting Resistance Equivalent Number) ≥ 35–45
✅ Yield Strength 2–3× Higher than 316L Stainless Steel
✅ Excellent Resistance to Chloride-Induced SCC
✅ Hot-Rolled + Solution Annealed for Optimal Microstructure
✅ Available with Laser/Plasma Cutting, Beveling & Testing
Grade Comparison: Chemical & Mechanical Properties
| Property / Alloy | S32205 (2205) | S32750 (2507) | S32550 (Ferralium 255) |
|---|---|---|---|
| Classification | Standard Duplex | Super Duplex | Super Duplex |
| EN Number | 1.4462 | 1.4410 | 1.4501 |
| PREN (Min.) | ≥35 | ≥40 | ≥38 |
| Chromium (Cr) | 21–23% | 24–26% | 24–27% |
| Nickel (Ni) | 4.5–6.5% | 6.0–8.0% | 4.5–6.5% |
| Molybdenum (Mo) | 2.5–3.5% | 3.0–4.0% | 2.9–3.9% |
| Nitrogen (N) | 0.14–0.20% | 0.24–0.32% | 0.20–0.30% |
| Copper (Cu) | – | – | 1.5–2.5% (enhances acid resistance) |
| Tensile Strength | 620–890 MPa | 750–1000 MPa | 750–950 MPa |
| Yield Strength (0.2%) | ≥450 MPa | ≥550 MPa | ≥550 MPa |
| Elongation | ≥25% | ≥25% | ≥25% |
| Max Hardness (HB) | ≤290 | ≤320 | ≤310 |
PREN Formula: %Cr + 3.3×%Mo + 16×%N
Higher PREN = better resistance to localized corrosion in chloride-rich media.
Typical Applications by Grade
| Alloy | Industry Applications |
|---|---|
| S32205 | Offshore platforms, chemical storage tanks, heat exchangers, pulp & paper digesters, seawater piping |
| S32750 | Subsea manifolds, deep-sea risers, flue gas desulfurization (FGD), seawater injection systems, aggressive acid handling |
| S32550 | Marine pump shafts, valve stems, propeller blades, sulfuric/phosphoric acid equipment, high-wear corrosive environments |
All three alloys are unsuitable for continuous service below -50°C due to potential ferrite embrittlement.
