High-Performance Duplex Stainless Steel, Cut to Your Exact Requirements

When your application demands exceptional strength, superior corrosion resistance, and precision fabrication, Duplex Stainless Steel Grades S32205 (2205), S31803, and S32750 (2507) deliver unmatched performance. We specialize in CNC laser cutting of hot-rolled duplex stainless steel plates in any size, shape, or thickness from 3.0 mm to 40.0 mm, ensuring rapid turnaround, tight tolerances, and material integrity for the most demanding industries—including oil & gas, marine, chemical processing, desalination, and offshore engineering.
Whether you need a single prototype or high-volume production parts, our advanced fiber and CO₂ laser systems provide clean, accurate cuts with minimal heat-affected zones—preserving the critical dual-phase microstructure that gives duplex steels their renowned durability.

Material Grades Overview

UNS NumberCommon NameTypeKey Characteristics
S32205Duplex 2205Standard DuplexBalanced strength & corrosion resistance; ideal for moderate chloride environments
S31803Duplex 2205 (older spec)Standard DuplexChemically similar to S32205; often used interchangeably (modern mills typically meet S32205 tighter limits)
S32750Super Duplex 2507Super DuplexUltra-high pitting resistance (PREN >40); suited for seawater, sour service, and aggressive chemicals
Note: While S31803 and S32205 are often grouped together, S32205 has stricter compositional controls (especially nitrogen content) and is preferred for critical applications. All three grades are fully compatible with our laser cutting process.

Why Laser Cut Duplex Stainless Steel?

Traditional cutting methods like plasma or oxy-fuel can compromise duplex steel’s corrosion resistance by altering its microstructure or leaving oxidized edges. Laser cutting eliminates these risks:
  • ✅ No thermal distortion in thin-to-medium thicknesses
  • ✅ Smooth, dross-free edges—often eliminating secondary finishing
  • ✅ Complex geometries cut directly from CAD (DXF, DWG, STEP)
  • ✅ Material savings through intelligent nesting software
  • ✅ Preserved mechanical & corrosion properties due to controlled, localized heat input
Our process uses high-purity nitrogen assist gas to prevent oxide scale formation, ensuring cut surfaces maintain the alloy’s inherent resistance to pitting and stress corrosion cracking.

Performance Comparison: S32205 vs. S32750

PropertyS32205 / S31803S32750 (2507)
Chromium (Cr)~22%~25%
Molybdenum (Mo)~3.0–3.5%~3.5–4.0%
Nickel (Ni)~4.5–6.5%~6.0–8.0%
Nitrogen (N)0.14–0.20%0.24–0.32%
PREN (Pitting Resistance Equivalent)34–3840–45
Yield Strength (min)450 MPa550 MPa
Max Chloride ExposureUp to ~1,000 ppmUp to ~5,000+ ppm
Typical Use CaseChemical tanks, pipelinesSubsea manifolds, seawater systems
PREN = %Cr + 3.3×%Mo + 16×%N — a higher value indicates greater resistance to localized corrosion.

Applications by Industry

  • Oil & Gas: Downhole equipment, flowlines, separators, pressure vessels
  • Marine & Offshore: Seawater cooling systems, risers, FPSO structural components
  • Chemical Processing: Reactors, heat exchangers, acid storage tanks
  • Desalination Plants: High-pressure membrane housings, brine heaters
  • Power Generation: Flue gas desulfurization (FGD) ducts, scrubber internals
  • Pulp & Paper: Bleach plant equipment, digester components
These alloys outperform 316L and even 904L in chloride-rich or acidic environments—reducing maintenance, extending service life, and lowering total lifecycle costs.

Custom Laser Cutting – No Size Too Big or Small

We accept any size requirement:
  • Small brackets (50×50 mm)
  • Large structural panels (up to 3000×12000 mm with plate joining)
  • Intricate perforated patterns, flanges, gaskets, or weld-ready profiles
Simply provide your CAD file, and we’ll deliver:
  • Nesting optimization for cost efficiency
  • Burr-free edges ready for assembly
  • Full documentation (MTRs, PMI reports, dimensional inspection)

Quality Assurance & Compliance

Every batch is traceable to the original melt. Optional services include:
  • Positive Material Identification (PMI) via XRF or OES
  • Ultrasonic Testing (UT) for plates >20 mm (per ASTM A435/A578)
  • Pickling & Passivation to restore optimal surface chromium oxide layer
  • Welding procedure support (we recommend qualified procedures to avoid sigma phase formation)

Sustainable, Cost-Effective Engineering

While duplex stainless steels carry a higher upfront cost than austenitic grades, their double the strength allows for thinner sections, reducing weight and material usage. Combined with decades-long service life in corrosive environments, they offer superior ROI—especially in hard-to-access or safety-critical installations.
