Weld Star – ER 2209|Duplex TIG Wire (3.2mm) 5kg
Features and Applications
Austenitic-ferritic duplex stainless steel wire characterised by its high tensile strength.
The weld metal offers excellent resistance to stress corrosion, cracking and pitting.
Ideal for joining 22% Cr duplex stainless steel base materials, commonly called 2205.
The ferrite content of the weld metal will be lower than the ferrite content of 2205 base metals.
Recommended working temperature ranges from cryogenic to 300°C.
Typically used in the petrochemical and offshore industries, acid gas industry and on chemical transportation equipment etc.
