Product Features & Technical Specifications
- Superior Corrosion Resistance – 2205 duplex stainless steel offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-containing environments.
- High Strength – Yield strength approximately twice that of conventional 304 or 316 stainless steel, allowing for thinner sections and weight reduction.
- Excellent Weldability – Suitable for standard welding processes; proper filler metal selection ensures optimal joint performance.
- Good Toughness – Maintains ductility and impact resistance even at low temperatures.
- Custom Cutting Service – We offer laser, plasma, and shearing cutting to your exact dimensions, with tolerances as tight as ±0.5mm.
- Wide Size Range – Standard widths from 1000mm to 2500mm, lengths from 2000mm to 6000mm, with custom sizes available upon request.
- Surface Finish Options – Choose from 2B (cold rolled, bright), No.1 (hot rolled, annealed), or BA (bright annealed) to suit your aesthetic and functional requirements.

Frequently Asked Questions
- What is the difference between 2205 and 316L stainless steel? 2205 duplex stainless steel has nearly double the yield strength of 316L and offers superior resistance to chloride stress corrosion cracking, making it more suitable for aggressive environments like offshore and chemical processing.
- Can you provide a material test certificate? Yes, we can supply a mill test certificate (MTC) per EN 10204 3.1 or 3.2 upon request, confirming chemical composition and mechanical properties.
- What cutting methods do you offer? We offer laser cutting (best for precise edges and tight tolerances), plasma cutting (for thicker plates), and shearing (for straight cuts). The choice depends on your thickness and finish requirements.
- Do you sell plates in thicknesses other than 3mm, 5mm, and 8mm? Yes, we can supply 2205 duplex plates in a range of thicknesses from 1mm to 50mm or more. Contact our sales team for availability.
- How do you ensure the quality of the plates? Our production follows ISO9001‑certified quality management. Each batch is inspected for dimensional accuracy, surface quality, and chemical analysis. We also arrange third‑party inspection if required.
- What is the typical lead time for custom-cut plates? For standard sizes (3mm, 5mm, 8mm), lead time is 5–10 working days. For custom dimensions or large quantities, it may extend to 15–20 working days, depending on your order volume.
- Can you paint or coat the plates? We do not offer painting or coating as standard, but we can arrange for additional surface treatments (e.g., pickling, passivation) through our partners. Please inquire for details.
- Do you provide samples before mass production? Yes, we can provide small samples (e.g., 200mm × 200mm) at a nominal cost, which will be deducted from your first bulk order. Shipping fees apply.
