What are Super Duplex Steel UNS S32760 Sheets & Plates?

Super Duplex Steel UNS S32760 sheets and plates are flat-rolled products made from super duplex stainless steel with a dual-phase microstructure of austenite and ferrite. This composition delivers superior strength and corrosion resistance compared to standard duplex and austenitic stainless steels.

UNS S32760 (also known as Zeron 100) is specifically designed for extreme environments where high resistance to corrosion, erosion, and stress is required.

Key Functions:

  • Provide exceptional strength and structural stability
  • Resist corrosion in aggressive and high-chloride environments
  • Ensure long-term durability and reliability
  • Perform efficiently under high pressure and temperature conditions

Chemical Composition of Super Duplex Steel UNS S32760

Typical Composition:

  • Chromium (Cr): 24% – 26%
  • Nickel (Ni): 6% – 8%
  • Molybdenum (Mo): 3% – 4%
  • Nitrogen (N): 0.20% – 0.30%
  • Copper (Cu): 0.5% – 1.0%
  • Tungsten (W): 0.5% – 1.0%
  • Iron (Fe): Balance
  • Manganese (Mn): ≤ 1%
  • Silicon (Si): ≤ 1%

The addition of copper and tungsten further enhances resistance to corrosion and improves mechanical performance.
