Applications

Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.

  • Duplex stainless steels are typically used in:
  • Chemical processing, transport and storage
  • Oil and gas exploration and offshore rigs
  • Oil and gas refining
  • Marine environments
  • Pollution control equipment
  • Pulp & paper manufacturing
  • Chemical process plant
