Super duplex stainless steels are mainly developed to be used in extreme stress environments. The properties of this alloy are very high which include, toughness, strength, corrosion resistance to a decent number of organic and inorganic acids. Super duplex steels are similar to the standard duplex types, but they contain a higher content of chromium which enhances the mechanical properties as well as its corrosion resistance. Normally a super duplex stainless steel contains 25% of chromium, 4% of molybdenum and 7% of nickel. It is particularly suited for warm-water chlorinated environments and acidic, chloric containing systems. Super duplex types always show good fatigue strength and that’s why they are always much preferred over standard duplex ones.

  • It has guaranteed resistance to all types of corrosion.
  • Supreme resistance to chloride corrosion stress cracking.
  • Beneficial combination of both ferrite and austenite properties.
  • Suggested for applications and experiments which need temperature up to 6000F.
  • The low rate of thermal expansion.
  • Excellent weldability and workability.
  • Excellent mechanical properties.
  • Good abrasion and erosion resistance.
  • Good resistance to fatigue and energy absorption.
  • High resistance to pitting and crevice erosion.
  • Mainly used in Oil and Gas Industries.
  • Pulp and paper industries.
  • Desalination equipment.
  • Mining and mineral industries.
  • Marine industries.
  • Power generation.
  • Flue-gas desulfurization.
  • Chemical and pharmaceutical industries.
  • Marine Industries and applications.
  • Chemical process pressure vessels.
  • Piping systems and Heat exchangers.
