SAF 2205™ is a duplex (austenitic-ferritic) stainless steel characterized by:

  • High resistance to stress corrosion cracking (SCC) in chloride-bearing environments
  • High resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulfide
  • High resistance to general corrosion, pitting, and crevice corrosion
  • High resistance to erosion corrosion and corrosion fatigue
  • High mechanical strength - roughly twice the proof strength of austenitic stainless steel
  • Physical properties that offer design advantages
  • Good weldability
