Premium 2507 Super Duplex Stainless Steel Plate & Sheet – High Corrosion Resistance for Offshore & Chemical Applications
Product Overview
Engineered for the most aggressive environments, Premium UNS S32750 (Alloy 2507) Super Duplex Stainless Steel Plate and Sheet delivers unmatched corrosion resistance, exceptional mechanical strength, and long-term reliability in offshore oil & gas, chemical processing, desalination, and marine engineering applications.
With a precisely balanced dual-phase microstructure—approximately 50% ferrite and 50% austenite—Alloy 2507 outperforms standard austenitic grades (like 316L) and even conventional duplex steels (e.g., 2205) in chloride-rich, acidic, and high-pressure conditions. Our premium-grade plates and sheets are manufactured to stringent international standards including ASTM A240, EN 10088-2, NACE MR0175/ISO 15156, and ASME Section II, ensuring compliance with global industrial safety and performance requirements.
Available in thicknesses from 1.0 mm to 30.0 mm, our inventory supports custom cutting (laser, waterjet, plasma) to exact project specifications—reducing fabrication time and material waste while accelerating deployment.
Why Choose Premium-Grade Alloy 2507?
✅ Superior Corrosion Resistance: Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) even in seawater and sour (H₂S-containing) environments
✅ High Strength: Yield strength >550 MPa—nearly twice that of 316L—enabling lighter, thinner designs
✅ Excellent Performance at Elevated Temperatures: Stable up to 300°C (572°F) without embrittlement
✅ NACE MR0175 Certified: Approved for use in sour service oil & gas applications
✅ Full Traceability & Certification: Mill Test Reports (EN 10204 3.1/3.2), PMI, and UT testing available

Mechanical Properties (Solution Annealed, 1050°C + Quench)
| Property | Typical Value |
|---|---|
| Tensile Strength | 800–1000 MPa |
| Yield Strength (0.2% offset) | ≥550 MPa |
| Elongation | ≥25% |
| Hardness | ≤290 HB |
| Density (20°C) | 7.8 g/cm³ |
| PREN (Pitting Resistance Equivalent Number) | ≥40 |
PREN = %Cr + 3.3×(%Mo) + 16×(%N) — A value >40 classifies Alloy 2507 as a super duplex, offering elite-level resistance to localized corrosion.
Corrosion Performance Highlights
| Environment | Performance |
|---|---|
| Seawater (natural or synthetic) | Excellent resistance; widely used in offshore platforms and subsea systems |
| Chloride solutions (up to 6% NaCl) | No pitting or SCC below 70°C |
| Sour gas (H₂S + CO₂) | Compliant with NACE MR0175 for partial pressure H₂S up to 0.3 bar |
| Acidic media (sulfuric, hydrochloric) | Good resistance in moderate concentrations and temperatures |
| Bleach & pulp processing | Resists oxidation and chloride attack in bleach plants |
Critical Pitting Temperature (CPT) in 6% FeCl₃: ≥70°C

Target Industrial Applications
| Industry | Key Uses |
|---|---|
| Offshore Oil & Gas | Subsea manifolds, risers, Christmas trees, flowlines, separators |
| Chemical Processing | Reactors, heat exchangers, storage tanks, piping for acids and chlorides |
| Desalination Plants | RO membrane housings, high-pressure brine lines, evaporators |
| Marine Engineering | Seawater cooling systems, shipboard piping, ballast tanks |
| Power & Energy | Flue gas desulfurization (FGD) scrubbers, condenser tubes |
| Pulp & Paper | Bleach towers, washers, digesters exposed to chlorine dioxide |
Alloy 2507 is often specified where 316L fails prematurely due to pitting or SCC—delivering decades of service life with minimal maintenance.
Fabrication & Welding Guidelines
- Welding: Use consumables like ER2594 or 25.10.4L. Keep interpass temperature <100°C to avoid sigma phase formation. Shielding gas: Ar + 2–3% N₂.
- Machining: Requires rigid setups, sharp carbide tools, low cutting speeds, and high coolant flow.
- Forming: Cold bending radius ≥2× thickness. For severe forming, preheat to 200–300°C.
- Post-Fabrication: Pickling and passivation recommended after welding or grinding to restore passive layer.
Sustainability & Lifecycle Value
While Alloy 2507 has a higher upfront cost than standard stainless steels, its extended service life, reduced downtime, and lower replacement frequency deliver compelling total cost of ownership (TCO) advantages—especially in critical infrastructure.
Additionally, stainless steel is 100% recyclable, supporting ESG goals and circular economy initiatives.
Order & Support Information
- MOQ: As low as 1 piece for cut-to-size orders
