Sandvik SAF 2205 Seamless tube and pipe
Categories:	Metal; Ferrous Metal; Duplex; Stainless Steel
Material Notes:	Sandvik SAF 2205 is a duplex (austenitic-ferritic) stainless steel. It is characterized by: high resistance to stress corrosion cracking in chloride-bearing environments and 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 Information provided by Sandvik UNS S31803, S32205; EN 1.4462
