Disclaimer: Recommendations are for guidance only, and the suitability of a material for a specific application can be confirmed only when we know the actual service conditions. Continuous development may necessitate changes in technical data without notice. This datasheet is only valid for Sandvik materials.

Sandvik 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 sulphide
  • 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
