Classifications

• AWS A5.9 - ER2209

Features: 

• Resistance to Pitting and Chloride induced stress corrosion cracking is maintained with Ferrite levels >30-50FN & PREN >35 typically. 
• The microstructure of the weld metal consists of austenite and ferrite 
• Welding of duplex stainless steels calls for controlled welding parameters to achieve specified mechanical and corrosion resistant properties 
• Care should be taken with welding heat input & Interpass temperature to ensure correct microstructure is achieved with approximately 50/50 austenite and Ferrite matrix. 
• Flux-cored 1.2mm Dual shield Wire. 
• Use with 100% Co2 or Argon Heavy mix 20% minimum Co2. 
• For welding 2205 Base material also. 
• High-Quality Cobra Brand Wire.
