15kg – 1.2mm ER2209 Duplex Stainless Steel Flux cored wire

For welding wrought, forged or cast 22Cr duplex stainless steels for severe service in the as-welded condition.
Heterogeneous welding between 22Cr duplex stainless steels and other stainless and low alloyed steels.

Welding typically of materials EN 1.4462, S32205, SAF 2205 or Casting grade equivalents. 

Classifications

AWS A5.22 – ER2209T1-1

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.
