UNS S32750 Super Duplex

uns-s32750-super-duplex-product-image

UNS S32750 Super Duplex Stainless Steel (1.4410 material) is a premium super duplex alloy for ultra aggressive environments. This S32750 material offers very high strength along with outstanding resistance to pitting, crevice, and stress-corrosion cracking in chloride and sulphide rich conditions.

Key Features

Featuring elevated chromium, molybdenum, and nitrogen, this grade delivers exceptional corrosion resistance and mechanical performance. Its duplex microstructure provides high yield strength, excellent toughness, and reliability for critical applications in oil & gas, chemical, and marine industries.

Typical Applications
  • Offshore drilling platforms, risers, subsea manifolds and piping
  • Desalination plants, seawater systems and marine structural components
  • Chemical processing, pulp & paper, flue gas desulphurisation (FGD) equipment
  • Pressure vessels, heat exchangers and high load structural parts in hostile environments
  • High‑strength, corrosion resistant components in harsh offshore, chemical or marine settings
Forms of Supply

Supplied in square bars, round bars, hex bars, flat bars, blocks, sheets, and plates in solution annealed condition. Cut to size, machined, and finished options are available. Silver Metal Trading LLC is a trusted stainless steel supplier in UAE and also supplies UNS S32750 Super Duplex to Saudi Arabia and Oman, operating as a leading metal trading partner in the ferrous metal segment.

Technical Specifications

Specifications
  • Carbon (C): ≤ 0.030% – limits carbide precipitation and preserves corrosion resistance.
  • Silicon (Si): ≤ 0.80% – assists de‑oxidation and structural stability.
  • Manganese (Mn): ≤ 1.20% – improves toughness and strength.
  • Phosphorus (P): ≤ 0.035% – helps maintain cleanliness and ductility.
  • Sulfur (S): ≤ 0.020% – ensures weldability and high corrosion resistance.
  • Chromium (Cr): 24.0‑26.0% – provides superior corrosion resistance and strength.
  • Nickel (Ni): 6.0‑8.0% – enhances toughness and stabilises microstructure.
  • Molybdenum (Mo): 3.0‑5.0% – significantly boosts resistance to pitting and crevice corrosion.
  • Nitrogen (N): 0.24‑0.32% – improves both strength and corrosion resistance.
  • Iron (Fe): Balance – main matrix element.
Certifications
  • Standard Mill Test Certificate (MTC) supplied covering chemical and mechanical test data.
  • EN 10204 3.1 / 3.2 inspection certificates or equivalent third‑party verification available upon request.
  • Conforms with standards such as ASTM A182/A815, ASME, NORSOK for super‑duplex grades.
  • Project‑specific traceability, third‑party inspection, NDT or custom certification packages can be arranged — please contact our sales team for requirements.
