3. SEFUL INFO:
Duplex 2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. Often referred to as the work horse grade, 2205 is the most widely used grade in the duplex family of stainless steels.

2205 is a duplex (austenitic-ferritic) stainless steel characterized by:
High resistance to stress corrosion cracking (SCC) in chloride-bearing environments
High resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulphide
High resistance to general corrosion, pitting, and crevice corrosion
High resistance to erosion corrosion and corrosion fatigue
High mechanical strength - roughly twice the proof strength of austenitic stainless steel
Physical properties that offer design advantages
Good weldability
