High corrosion resistant Duplex Stainless Steel filler rod
Avesta 2205 is primarily designed for welding the duplex grade Outokumpu 2205 and similar but it can also be used for SAF 2304 type of steels. Avesta 2205 provides a ferritic-austenitic weldment that combines many of the good properties of both ferritic and austenitic stainless steels. Welding without filler metal (i.e. TIG-dressing) is not allowed since the ferrite content will increase drastically and both mechanical and corrosion properties will be negatively affected.
Structure: Austenite with 45 – 55 % ferrite.
Scaling temperature: Approx. 850 °C (air).
Corrosion resistance:Very good resistance to pitting and stress corrosion cracking in chloride containing environments.
- Spec: AWS A5.9 ER2209
- Wire Diameter: 1.6mm, 2.4mm
- Approvals: TÜV, DB, DNV, CE
