Sanmac^® 2205 is a duplex (austenitic-ferritic) stainless steel with improved machinability. The grade is characterized by:

Excellent machinability
High resistance to stress corrosion cracking (SCC) in chloride-bearing environments
High resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulfide
High resistance to general corrosion, pitting and crevice corrosion
High mechanical strength – roughly twice the proof strength of austenitic stainless steels
Good hot-working properties
High resistance to erosion corrosion and corrosion fatigue
Physical properties that offer design advantages
Good weldability
