Sandvik SAF 2304 is a lean duplex (austenitic-ferritic) stainless steel characterized by the following properties:

  • Very good resistance to stress corrosion cracking (SCC)
  • Good resistance to general corrosion and pitting
  • High strength - approximately twice the proof strength of austenitic stainless steels
  • Physical properties that offer design advantages
  • Ease of fabrication and good toughness
  • Good weldability
