Product Description
UNS S32750 (2507) Super Duplex Stainless Steel Overview
UNS S32750 (2507) is a premium super duplex stainless steel that combines the superior corrosion resistance of austenitic steels with the mechanical strength of ferritic steels. With high chromium (25%), molybdenum (4%), and nitrogen (0.3%) content, it delivers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), making it ideal for offshore, chemical, and desalination industries.

Product Features
  • Extreme Corrosion Resistance: Superior resistance to chlorides, sulfuric acid, and seawater, outperforming 316L and 2205 duplex steel
  • High Mechanical Strength: Twice the yield strength of 316L, enabling thinner, lighter designs without compromising durability
  • Excellent Weldability & Fabricability: Compatible with TIG, MIG, and SAW welding (use 2594 filler metal)
  • Stress Corrosion Cracking (SCC) Resistance: Performs reliably in H2S-containing (sour gas) and high-stress environments
  • Cost Efficiency: Longer lifespan than standard duplex steels, reducing replacement and maintenance costs
Core Advantages
  • Unrivaled PREN Value: PREN ≥40 ensures top-tier pitting/crevice corrosion resistance
  • Global Certifications: Complies with ASTM A790, EN 10088, NORSOK M-630, and ASME SA-182
  • Custom Solutions: Available in plates, pipes, fittings, bars, and custom-machined components
  • Fast Delivery: Global logistics network supports urgent orders to Europe, Middle East, and Asia
  • Technical Support: Free guidance on welding, machining, and application design
Typical Applications
  • Oil & Gas: Subsea pipelines, Christmas trees, heat exchangers, pressure vessels
  • Desalination & Marine: Seawater reverse osmosis (SWRO) systems, pump shafts, ship propellers
  • Chemical Processing: Reactors, acid storage tanks, scrubbers, flue gas systems
  • Power Generation: FGD (flue gas desulfurization) systems, condenser tubes
  • Pulp & Paper: Bleaching equipment, digesters, chip chutes
  • Renewable Energy: Offshore wind turbine components, tidal energy systems
