EN 1.4462 & 1.4410 Duplex Stainless Steel Plate – Precision Laser Cutting, Thickness 2.0–80.0 mm, Smooth Edge Guaranteed
High-Performance Duplex Plates, Expertly Cut for Demanding Applications
We specialize in CNC laser cutting of EN 1.4462 (Duplex 2205) and EN 1.4410 (Super Duplex 2507) stainless steel plates in thicknesses ranging from 2.0 mm to 80.0 mm, delivering smooth, burr-free edges with tight dimensional tolerances. Whether you require simple blanks or complex components for oil & gas, marine, chemical processing, or desalination systems, our advanced cutting technology ensures your parts are fabrication-ready—often without secondary finishing.
Backed by full material traceability and compliance with EN 10088-2, ASTM A240, NORSOK M-650 (for 1.4410), and other global standards, our service combines metallurgical integrity with precision engineering.
Material Overview: EN 1.4462 vs. EN 1.4410
| Property | EN 1.4462 (Duplex 2205) | EN 1.4410 (Super Duplex 2507) |
|---|---|---|
| UNS Equivalent | S32205 / S31803 | S32750 |
| Type | Standard Duplex | Super Duplex |
| Microstructure | ~50% Austenite + 50% Ferrite | Balanced dual-phase (optimized for strength & corrosion) |
| PREN (Pitting Resistance)* | 34–38 | 40–45 |
| Yield Strength (Rp0.2) | ≥450 MPa | ≥550 MPa |
| Tensile Strength (Rm) | 620–750 MPa | 750–950 MPa |
| Max Service Temp | ~300°C | ~280°C |
| Key Alloying Elements | Cr 22%, Ni 5.5%, Mo 3.2%, N 0.17% | Cr 25%, Ni 7%, Mo 4%, N 0.28% |
| Typical Applications | Chemical tanks, heat exchangers, pipelines | Subsea manifolds, seawater systems, FGD scrubbers |
*PREN = %Cr + 3.3×%Mo + 16×%N — higher = better pitting resistance.
Laser Cutting Capabilities: 2.0–80.0 mm with Smooth Edges
Cutting thick duplex stainless steel requires specialized expertise to avoid microstructural degradation and edge defects. Our hybrid approach ensures quality across the full thickness range:
| Thickness Range | Cutting Technology | Edge Quality | Notes |
|---|---|---|---|
| 2.0 – 25.0 mm | High-power fiber laser | ISO 9013 Class 2 | Ultra-smooth, vertical kerf; minimal dross |
| 25.1 – 50.0 mm | High-precision CO₂ laser | ISO 9013 Class 2–3 | Clean cut with slight taper (<2°); nitrogen assist |
| 50.1 – 80.0 mm | Advanced oxygen-assisted CO₂ laser + post-processing | ISO 9013 Class 3 | Smooth finish achieved via optimized parameters and light grinding if required |
✅ All cuts use high-purity nitrogen or argon assist gas to prevent oxidation
✅ Heat input is tightly controlled to avoid sigma/chi phase formation in the HAZ
✅ Edges are smooth enough for direct welding or assembly in most cases

Why Smooth Edges Matter in Duplex Steels
Rough or oxidized cut edges can:
- Act as initiation sites for pitting or crevice corrosion
- Require time-consuming grinding before welding
- Compromise fatigue performance in dynamic loads
Our smooth-edge laser process eliminates these issues by:
- Preventing scale formation through inert gas shielding
- Minimizing recast layer and micro-cracks
- Maintaining the alloy’s natural passive layer integrity
This is especially critical for EN 1.4410, which is often used in seawater, sour gas, or high-chloride environments where surface quality directly impacts service life.
Applications by Industry
| Industry | Typical Components (Laser-Cut from 1.4462 / 1.4410) |
|---|---|
| Oil & Gas | Christmas trees, manifolds, choke valves, flowlines |
| Offshore & Marine | Riser clamps, seawater piping, ballast system parts |
| Chemical Processing | Reactor internals, distillation trays, acid storage vessels |
| Desalination | High-pressure RO housings, brine heater tubesheets |
| Power & Energy | Flue gas desulfurization (FGD) ducts, heat exchanger plates |
| Pulp & Paper | Bleach plant towers, digester components |
Quality Assurance Process
- Material Verification: All plates sourced from certified mills with full MTRs
- PMI Testing: Optional XRF/OES verification before and after cutting
- Process Control: Laser parameters logged per job (power, speed, gas pressure)
- Inspection: Visual + dimensional checks per ISO 9013; UT available for >40 mm
- Finishing: Optional pickling/passivation or light grinding for ultra-smooth edges
Ordering Information
- Minimum Order: 1 piece
- Lead Time: 5–15 working days (depending on thickness and complexity)
- Secondary Services: Beveling, marking (laser/engraving), protective film, export packaging
- Global Shipping: FOB, CIF, or DDP options available
