ZERON 100 Super Duplex

 

ZERON® 100 (F55 Duplex, 25cr Duplex) is a super duplex stainless steel that complies with UNS S32760, made for use in aggressive environments. Its properties include:

    • Resistant to pitting and crevice corrosion in warm seawater with a guaranteed corrosion performance (PREN > 40)
    • Lower more stable price compared to nickel based alloys
    • Excellent resistance to stress corrosion cracking in both chloride and sour environments
    • Superior resistance to sulfuric acid at most concentrations
    • Improved resistance over austenitic stainless to erosion corrosion and corrosion fatigue
 
  • High Strength (80,000 psi minimum Yield Strength) permitting designs to reduce weight versus other corrosion resistant alloys
  • Readily weldable using ZERON 100X filler metal

While ZERON 100 complies with UNS S32760, Rolled Alloys tightly controls the chemistry and production of ZERON 100 in strict accordance with the requirements of our in-house which are tighter than standard ASTM specifications. 

 

Performance Profile

ZERON 100 was developed as a seawater resistant material for pump applications in the North Sea as a cast material. Its excellent performance, led to demand for the alloy in a wider range of product forms and the development of wrought product forms. The corrosion resistance and strength properties of ZERON 100 have led to its widespread adoption in a range of industries. Oil and gas applications include process, seawater, firewater and subsea pipework systems, with associated risers, manifolds, pressure vessels, valves and heat exchangers. Applications of ZERON® 100 (UNS S32760) in other industries include pollution control equipment such as flue gas desulfurization equipment (FGD), pulp and paper, power generation, chemical, pharmaceutical, desalination, mining, metallurgical and marine industries.

Optimized versions of ZERON 100 are available for specific applications. These include:

  • ZERON 100 FG (fastener grade) which is a strain hardened bar product available up to 2-1/2 inch diameter for high strength fasteners. ZERON 100 FG is made to ASTM A276 condition S and also meets the tensile properties for ASTM A193 grade B7. It meets charpy impact toughness of 40 Joules (29.5 ft.lbf.) minimum at -50°C (-58°F).
  • ZERON 100X overalloyed weld filler for welding of ZERON 100 to itself and other stainless steels.
  • ZERON 100M matching weld filler for welding ZERON 100 components that will be post weld annealed.
  • ZERON 100HS (high strength) wire for slick line applications in oil and gas.

The copper addition in ZERON 100 is responsible for its enhanced resistance to sulfuric acid. ZERON 100 super duplex is superior to the more expensive grades such as alloy 20 or alloy 825 and is superior to duplex 2205 and 2507 super duplex at most concentrations. ZERON 100 super duplex also compares favorably to high silicon austenitic stainless steels, such as ZeCor®, SX, and Saramet in hot concentrated sulfuric acid. The iso-corrosion curves below show the 0.1 mm/year (0.004 ipy) corrosion lines for ZERON 100 super duplex and other alloys in dilute sulfuric and concentrated sulfuric acid
