SAF 3207 HD™ is a hyper-duplex (austenitic-ferritic) stainless steel for service in highly corrosive conditions where also high mechanical strength is necessary. This makes the grade ideal for applications such as deepwater umbilicals. SAF 3207 HD™ is characterized by:

  • Excellent resistance to pitting and crevice corrosion
  • Excellent resistance to stress corrosion cracking (SCC) in hydrogen sulphide (H2S) and chloride containing environments
  • High resistance to general corrosion in acidic and caustic environments
  • Excellent resistance to erosion corrosion
  • Excellent corrosion fatigue properties
  • Exceptionally high mechanical strength
  • Exceptionally high fatigue strength
  • Physical properties that offer design advantages
  • Good weldability
