Duplex 2205 / 2507 / S32550 / S32101 Stainless Steel Plate – Thickness 3.0–30.0 mm – Hot Rolled
Product Overview
We supply a comprehensive range of hot-rolled duplex stainless steel plates in four key grades:
- 2205 (UNS S32205 / S31803, EN 1.4462) – Standard Duplex
- 2507 (UNS S32750, EN 1.4410) – Super Duplex
- S32550 (UNS S32550, EN 1.4501) – Super Duplex (Ferralium® 255 equivalent)
- S32101 (UNS S32101, EN 1.4162) – Lean Duplex
Available in thicknesses from 3.0 mm to 30.0 mm, these plates are ideal for demanding applications in oil & gas, chemical processing, marine engineering, desalination, and infrastructure, where high strength, corrosion resistance, and cost efficiency are critical.
All plates are hot-rolled, solution-annealed, and rapidly quenched to ensure optimal dual-phase microstructure (ferrite + austenite), maximizing mechanical performance and resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC).
Grade Comparison at a Glance
| Property / Grade | 2205 (S32205) | 2507 (S32750) | S32550 | S32101 (Lean Duplex) |
|---|---|---|---|---|
| Type | Standard Duplex | Super Duplex | Super Duplex | Lean Duplex |
| PREN (Min.) | ≥35 | ≥40 | ≥38 | ≥25 |
| Yield Strength (MPa) | ≥450 | ≥550 | ≥550 | ≥450 |
| Tensile Strength (MPa) | 620–890 | 750–1000 | 750–950 | 650–850 |
| Chloride Resistance | Excellent | Exceptional | Exceptional | Good |
| Cost Level | Medium | High | High | Low |
| Typical Use | Offshore, chemical tanks | Subsea, aggressive acids | Marine pumps, valves | Bridges, transport, mild corrosive env. |
PREN = %Cr + 3.3×%Mo + 16×%N – Higher PREN = better pitting resistance.
Chemical Composition (Typical %)
| Element | 2205 | 2507 | S32550 | S32101 |
|---|---|---|---|---|
| Cr | 21.0–23.0 | 24.0–26.0 | 24.0–27.0 | 21.0–22.0 |
| Ni | 4.5–6.5 | 6.0–8.0 | 4.5–6.5 | 1.35–2.0 |
| Mo | 2.5–3.5 | 3.0–4.0 | 2.9–3.9 | 0.1–0.8 |
| N | 0.14–0.20 | 0.24–0.32 | 0.20–0.30 | 0.20–0.25 |
| C | ≤0.03 | ≤0.03 | ≤0.04 | ≤0.04 |
| Mn | ≤2.0 | ≤1.5 | ≤1.5 | ≤5.0 |
| Cu | – | – | 1.5–2.5 | – |
| W | – | 0.5–1.0 | – | – |
Note: S32101 replaces expensive nickel with manganese and nitrogen—ideal for cost-sensitive structural uses.
Mechanical Properties (As per ASTM A240 / EN 10088-2)
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HB max) |
|---|---|---|---|---|
| 2205 | 620–890 | ≥450 | ≥25 | ≤290 |
| 2507 | 750–1000 | ≥550 | ≥25 | ≤320 |
| S32550 | 750–950 | ≥550 | ≥25 | ≤310 |
| S32101 | 650–850 | ≥450 | ≥30 | ≤260 |
All grades exhibit excellent toughness down to -40°C (with controlled ferrite content).
