Sanmac® 2205 is a duplex (austenitic-ferritic) stainless steel with improved machinability. The grade is characterized by:

  • Excellent machinability
  • 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 mechanical strength – roughly twice the proof strength of austenitic stainless steels
  • Good hot-working properties
  • High resistance to erosion corrosion and corrosion fatigue
  • Physical properties that offer design advantages
  • Good weldability


  • : S31803, S32205
  • : 1.4462
  • : X2CrNiMoN22-5-3
