Sandvik SAF 2906™ is a high-alloy duplex (austenitic-ferritic) stainless steel with excellent corrosion resistance in caustic environments and environments with chlorides. Sandvik SAF 2906 characteristics:

  • Excellent resistance to caustic environments, also in the presence of contaminants such as chlorides
  • Excellent resistance to intergranular corrosion
  • Excellent resistance to pitting and crevice corrosion
  • High resistance to stress corrosion cracking (SCC)
  • Good weldability
  • Very high strength. The proof strength is about three times as high as for conventional austenitic stainless steels.
