Laser Cutting Duplex 2205 & 2507 Stainless Steel Plate – Hot Rolled, Thickness 3.0–40.0mm
Overview
Duplex stainless steels have become indispensable in demanding industrial environments where high strength, excellent corrosion resistance, and cost-efficiency are critical. Among the most widely used grades are Duplex 2205 (UNS S32205/S31803) and Super Duplex 2507 (UNS S32750). These alloys combine the best attributes of austenitic and ferritic stainless steels—offering roughly twice the yield strength of standard austenitic grades like 304 or 316, along with superior resistance to stress corrosion cracking, pitting, and crevice corrosion—especially in chloride-rich environments.
Our laser-cut Duplex 2205 and 2507 hot-rolled stainless steel plates, available in thicknesses from 3.0 mm to 40.0 mm, are engineered for precision applications across oil & gas, chemical processing, marine engineering, desalination plants, and offshore platforms. With advanced CNC laser cutting capabilities, we deliver components with tight tolerances, smooth edges, and minimal heat-affected zones—ensuring structural integrity and performance in harsh service conditions.
Why Choose Laser-Cut Duplex Stainless Steel Plates?
Laser cutting offers unmatched precision, repeatability, and edge quality for duplex stainless steel. Unlike plasma or flame cutting, fiber laser technology minimizes thermal distortion and oxidation, preserving the material’s dual-phase microstructure (approximately 50% austenite + 50% ferrite)—which is essential for maintaining mechanical and corrosion-resistant properties.
Key advantages include:
- High dimensional accuracy (±0.1 mm tolerance achievable)
- Clean, burr-free edges requiring little to no post-processing
- Complex geometries without tooling costs
- Material efficiency through optimized nesting software
- Preservation of corrosion resistance due to controlled heat input
Material Comparison: Duplex 2205 vs. Super Duplex 2507
| Property | Duplex 2205 (S32205/S31803) | Super Duplex 2507 (S32750) |
|---|---|---|
| Composition (Typical wt%) | Cr: 22%, Ni: 5.5%, Mo: 3.2%, N: 0.17% | Cr: 25%, Ni: 7%, Mo: 4%, N: 0.28% |
| PREN (Pitting Resistance Equivalent Number)* | 34–38 | 40–45 |
| Yield Strength (Rp0.2) | ≥450 MPa | ≥550 MPa |
| Tensile Strength (Rm) | 620–750 MPa | 750–950 MPa |
| Elongation at Break | ≥25% | ≥25% |
| Max Service Temp (Continuous) | ~300°C | ~280°C |
| Chloride SCC Resistance | Excellent (2–3× better than 316L) | Exceptional (2× better than 2205) |
| Common Applications | Chemical tanks, heat exchangers, pipelines | Offshore risers, seawater systems, FGD scrubbers |
*PREN = %Cr + 3.3×%Mo + 16×%N — higher values indicate greater pitting resistance.

Performance Advantages in Critical Environments
1. Resistance to Chloride Stress Corrosion Cracking (SCC)
Both 2205 and 2507 excel where standard austenitic steels fail. In seawater, brine, or chemical processing plants with chlorides >1000 ppm, 2205 provides reliable service up to 60–80°C. For more aggressive conditions (e.g., >80°C or higher chloride concentrations), 2507 is preferred due to its higher chromium, molybdenum, and nitrogen content.
2. High Strength-to-Weight Ratio
With yield strengths nearly double that of 316L, duplex plates allow for thinner designs, reducing weight and material costs—especially valuable in offshore platforms and pressure vessels.
3. Thermal & Mechanical Stability
The balanced ferritic-austenitic structure ensures good toughness down to -50°C and stable performance under cyclic loading—ideal for dynamic marine or subsea applications.
Laser Cutting Process Considerations
Cutting duplex stainless steel requires optimized parameters to avoid:
- Excessive heat input, which can form harmful intermetallic phases (e.g., sigma phase) above 300°C during slow cooling.
- Nitrogen loss in the cut zone, potentially reducing local corrosion resistance.
Our process includes:
- High-pressure nitrogen assist gas to prevent oxide formation and maintain clean edges.
- Controlled cutting speeds to limit heat accumulation.
- Post-cut inspection via visual and dye-penetrant testing for critical applications.
For thicknesses >25 mm, we recommend stress-relief annealing at 1020–1100°C followed by rapid quenching if the part will be used in highly corrosive environments—though this is rarely needed for laser-cut components due to minimal HAZ.
Typical Applications
| Industry | Application Examples |
|---|---|
| Oil & Gas | Subsea manifolds, flowlines, Christmas trees, separators |
| Chemical Processing | Reactors, storage tanks, piping systems handling acids/chlorides |
| Marine & Offshore | Seawater piping, ballast systems, FPSO components |
| Desalination | High-pressure reverse osmosis membranes, brine heaters |
| Pulp & Paper | Digesters, bleach towers, recovery boilers |
| Power Generation | Flue gas desulfurization (FGD) ducts, heat exchangers |

Sustainability & Lifecycle Value
Duplex stainless steels offer long service life with minimal maintenance—reducing downtime and replacement costs. Their high recyclability (>90%) aligns with circular economy principles. While initial material cost is higher than 316L, the total cost of ownership is often lower due to extended lifespan and reduced wall thickness requirements.
