Equivalent to: GB/T 17854 2209 AWS A5.9 ER2209 BS EN ISO 14343-A-G 22 9 3 N L
Characteristics and Applications
The weld metal is of 22Cr-9Ni-3Mo-N grade, which is suitable for welding 22Cr duplex stainless steels such as UNS31803 (namely Alloy 2205). It features high strength, excellent porosity resistance and superior stress corrosion resistance.
Precautions
1.The flux must be baked at 350℃ for 1 hour before use and kept dry to prevent the formation of porosity.
2.Welding with high heat input is allowable.
3.When reusing the flux, mix it with an appropriate amount of new flux to ensure desirable welding quality.
