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

Key Technical Specifications

Chemical Composition (Typical – wt%)

Meets ASTM A240 / EN 1.4410 (W.Nr 1.4410) requirements.

Mechanical Properties (Solution Annealed, 1050°C + Quench)

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

Critical Pitting Temperature (CPT) in 6% FeCl₃: ≥70°C
Critical Crevice Temperature (CCT): ≥50°C

Product Availability & Customization

All materials are batch-traceable and stored in climate-controlled warehouses to prevent surface contamination.

Target Industrial Applications

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.
