    Zeron 100 Overview

Zeron 100, super duplex stainless steel, is a highly alloyed stainless steel designed for use in aggressive environments. High strength, toughness, excellent corrosion resistance and its resistance to corrosion in a wide range of organic and inorganic acids are just a few characteristics that make this duplex stainless steel attractive to a variety of industries. Lastly, it is highly resistant to strong alkalis and resists corrosion in many non-oxidizing acids.

Usage of this super duplex stainless steel is not recommended when it involves extended exposure to temperatures greater than 572° F. This exposure causes a substantial reduction in toughness.

Notice the chemical composition of duplex 2507 and Zeron 100 are similar however; Zeron 100 contains slightly more copper and tungsten.  The copper content (min. 0.5, max 1.0) permits excellent resistance to corrosion in many non-oxidizing and mineral acids like hydrochloric and sulfuric acid.   

What are the characteristics of Zeron 100, super duplex stainless steel?

  • Guaranteed corrosion performance (PREn ≥ 40)
  • Excellent corrosion resistance in mineral acids such as hydrochloric and sulfuric
  • High resistance to pitting and crevice corrosion
  • Excellent resistance to stress corrosion cracking in both chloride and sour environments
  • High resistance to erosion corrosion and corrosion fatigue
  • Excellent mechanical properties
  • Possibility for weight reduction over austenitic, standard duplex and nickel base alloys
  • Good weldability


ZERON® 100 is a super duplex stainless steel 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

ZERON 100 complies with UNS S32760, however, Rolled Alloys tightly controls the chemistry and production of ZERON 100 in strict accordance with the requirements of our in-house 'MDS' specifications which are tighter than standard ASTM specifications. This ensures a consistent quality product is produced with optimal corrosion resistance and charpy impact toughness.

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 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.
