| High Light | High Strength Duplex Stainless Steel Tube ，Duplex Stainless Steel Tube Corrosion Resistance | ||
Duplex stainless steel sheet is a family of stainless steel grades with a mixed austenitic-ferritic microstructure (approximately 50% austenite / 50% ferrite). This unique structure delivers approximately twice the yield strength of standard austenitic grades like 304 or 316, combined with excellent resistance to chloride stress corrosion cracking (SCC), pitting, and crevice corrosion.
Duplex stainless steel sheets are the material of choice for demanding applications in offshore platforms, chemical processing, desalination plants, oil & gas exploration, and marine engineering, where both strength and corrosion resistance are critical.
| Feature | Description |
|---|---|
| Microstructure | Austenitic + Ferritic (≈50/50) |
| Yield Strength | ≥550 MPa for Super Duplex (~2× 316L) |
| Corrosion Resistance | Excellent against SCC, pitting, and crevice corrosion |
| Weldability | Good, with proper procedures |
| Temperature Range | Up to 280°C for continuous service |
| PREN (Super Duplex) | ≥40 – ≥42 |
| Grade | UNS | Type | Yield Strength (min) | PREN | Key Application |
|---|---|---|---|---|---|
| 2304 | S32304 | Lean Duplex | ≥400 MPa | ~25 | Cost-effective alternative to 304/316 |
| 2205 | S32205 | Standard Duplex | ≥450 MPa | ~35 | Most widely used: structural & pressure vessels |
| 2507 | S32750 | Super Duplex | ≥550 MPa | ≥42 | Extreme environments; subsea, high chloride |
| Parameter | Range |
|---|---|
| Thickness | 0.3 mm – 200 mm |
| Width | 100 mm – 3500 mm |
| Length | 2000 mm – 12000 mm (custom available) |
| Standard | ASTM A240 / A480, ASME SA240, EN 10088-2, JIS G4304/G4305 |
| Finish | Code | Characteristics | Application |
|---|---|---|---|
| No.1 | Hot rolled, annealed & pickled | Original surface, industrial use | Pressure vessels, industrial equipment |
| 2B | Cold rolled, bright finish | Smooth, reflective | General fabrication, kitchen equipment |
| BA | Bright annealed | Mirror-like reflectivity | Decorative, appliances, ornaments |
| No.4 | Brushed | Matte, fine satin finish | Architectural, food processing |
| HL | Hairline | Continuous linear streaks | Elevators, building facades |
| 8K | Mirror | Highly reflective | Decorative, luxury finishes |
| Industry | Specific Applications |
|---|---|
| Oil & Gas | Subsea pipelines, risers, downhole tubing, flowlines |
| Offshore Platforms | Seawater systems, firewater lines, structural components |
| Chemical Processing | Heat exchangers, pressure vessels, reactors, tanks |
| Desalination | High-pressure brine piping, evaporators, RO systems |
| Marine Engineering | Seawater cooling systems, propeller shafts, and shipbuilding |
| Pulp & Paper | Bleaching plants, digester vessels |
| Flue Gas Desulfurization | Absorber towers, ductwork, scrubbers |
| Construction | Bridges, storage tanks, architectural facades |
| Corrosion Type | Performance |
|---|---|
| Pitting / Crevice | PREN ≥35 (2205) / ≥42 (2507) → excellent in chloride-rich environments |
| Stress Corrosion Cracking (SCC) | Highly resistant vs. austenitic grades in chloride media |
| General Corrosion | Superior to 304/316 in acids (sulfuric, formic, acetic) |
| Intergranular Corrosion | Low carbon content prevents sensitization |
