  • Excellent resistance to stress corrosion cracking in chloride-bearing environments
  • Excellent resistance to pitting and crevice corrosion
  • High resistance to general corrosion
  • Very high mechanical strength
  • Physical properties that offer design advantages
  • High resistance to erosion corrosion and corrosion fatigue good weldability
  • Excellent mechanical properties that allow for lighter constructions, more compact design and less welding
