Duplex 2205 duplex stainless steel alloy is 22% chromium, 2.5% molybdenum, and 4.5% of nickel, nitrogen alloyed stainless steel. 2205 is characterised by:
1.high mechanical strength �C roughly twice the proof strength of austenitic stainless steels.
2.physical properties that offer design advantages.
3.good weldability.
4.high resistance to stress corrosion cracking in chloride-bearing environments and in environments containing hydrogen sulphide.
5.high resistance to general corrosion, pitting and crevice corrosion.
6.high resistance to erosion corrosion and corrosion fatigue.
