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