6mm / 8mm / 10mm / 12mm Stainless Steel Plate – Grade 2205 (1.4462 / S31803 / S32205) – Standard Size 1500×6000 mm
Product Overview
We offer hot-rolled duplex stainless steel plates in Grade 2205, conforming to international designations UNS S32205 / S31803, EN 1.4462, and ASTM A240/A240M. Available in popular thicknesses of 6 mm, 8 mm, 10 mm, and 12 mm, each plate is manufactured to the standard dimension of 1500 mm (width) × 6000 mm (length)—ideal for structural, marine, chemical, and oil & gas applications requiring high strength and superior corrosion resistance.
These plates combine the benefits of austenitic and ferritic microstructures, delivering approximately twice the yield strength of 304/316 stainless steels while offering excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC)—especially in chloride-rich environments like seawater or chemical processing plants.
Key Specifications at a Glance
| Parameter | Value |
| Grade | 2205 (Duplex) |
| UNS Numbers | S32205 (modern), S31803 (legacy) |
| EN Number | 1.4462 |
| Thickness Options | 6 mm, 8 mm, 10 mm, 12 mm |
| Standard Size | 1500 mm × 6000 mm |
| Surface Finish | No.1 (Hot Rolled & Pickled) – optional 2B or brushed finish available |
| Manufacturing Process | Hot Rolled + Solution Annealed + Quenched |
| Tolerance (Thickness) | ±0.40 mm (per ASTM A480 for 6–12 mm range) |
| Flatness | ≤3.0 mm per meter |
Chemical Composition (Typical % – EN 1.4462)
| Element | Content (%) |
| Chromium (Cr) | 21.0 – 23.0 |
| Nickel (Ni) | 4.5 – 6.5 |
| Molybdenum (Mo) | 2.5 – 3.5 |
| Nitrogen (N) | 0.14 – 0.20 |
| Carbon (C) | ≤0.03 |
| Manganese (Mn) | ≤2.0 |
| Iron (Fe) | Balance |
Note: The balanced Cr-Ni-Mo-N chemistry ensures a PREN (Pitting Resistance Equivalent Number) ≥ 35.
Mechanical Properties (As per ASTM A240)
| Property | Minimum Value |
| Tensile Strength | 620 MPa |
| Yield Strength (0.2% offset) | 450 MPa |
| Elongation | 25% |
| Hardness (HB) | ≤290 |
| PREN | ≥35 |
This high strength-to-weight ratio allows engineers to reduce material thickness without compromising performance—leading to cost savings in fabrication and transportation.
Common Applications
Thanks to its robust performance, 2205 stainless steel plates are widely used in:
- Oil & Gas: Pipelines, manifolds, pressure vessels, offshore platforms
- Chemical Processing: Reactors, heat exchangers, storage tanks
- Marine Engineering: Seawater piping, desalination units, ship components
- Water Treatment: Reverse osmosis systems, filtration housings
- Pulp & Paper Industry: Digesters and bleach towers
Avoid prolonged exposure below -50°C due to potential embrittlement of the ferritic phase.
Standards & Certifications
All plates comply with:
- ASTM A240 / ASME SA-240
- EN 10088-2 (1.4462)
- ISO 15510
- NORSOK M-650 (available upon request for offshore projects)
Each shipment includes:
- Mill Test Report (MTR) per EN 10204 3.1
- Full chemical and mechanical test data
- Heat number traceability on every plate
Optional ultrasonic testing (UT) for critical service conditions.
Packaging & Delivery
- Packaging: Waterproof paper + PVC film wrapping, steel-strapped bundles
- Edge Protection: Wooden battens on all sides
- Marking: Grade, thickness, heat number, dimensions, and standard clearly labeled
- Lead Time:
- In-stock sizes (6–12 mm): 3–7 working days
- Custom cutting or surface finish: 7–12 days
- Shipping: Global delivery via container (FCL/LCL); FOB, CIF, or DDP terms available
Laser Cutting & Fabrication Services (Optional)
Need parts cut to size? We provide precision laser cutting for 6–12 mm 2205 plates:
- Max Cutting Area: 1500 × 6000 mm (full plate)
- Tolerance: ±0.1 mm
- File Formats Accepted: DXF, DWG, STEP, PDF
- Edge Quality: Smooth, minimal dross, ready for welding or assembly
Ideal for fabricating flanges, brackets, support frames, covers, and custom components.
Why Choose These 2205 Plates?
✅ Ready Stock: 6/8/10/12 mm in 1500×6000 mm – immediate dispatch
✅ Consistent Quality: Sourced from certified mills (e.g., TISCO, Acerinox, Outokumpu partners)
✅ Full Traceability: Every plate linked to mill certificate
✅ One-Stop Solution: Supply + cutting + edge grinding + logistics
Technical Comparison: 2205 vs 316L
| Feature | 2205 Duplex | 316L Austenitic |
| Yield Strength | ~450 MPa | ~200 MPa |
| PREN | ≥35 | ~25 |
| SCC Resistance | Excellent | Moderate |
| Cost Efficiency | Higher upfront, lower lifecycle cost | Lower material cost, higher weight |
| Weldability | Good (with control) | Excellent |
2205 is preferred where strength, corrosion resistance, and weight matter more than extreme formability.
