DETAILS
LINCOLN® ER2209 provides excellent resistance to stress corrosion, cracking and pitting. Welding of duplex stainless calls for controlled welding parameters to achieve specified mechanical and corrosion resistant properties.
Features
- The welds offer excellent resistance to stress corrosion, cracking and pitting
- The microstructure of the weld metal consists of austenite and ferrite
- The ferrite content of the weld metal will be lower than the ferrite content of type 2205 base metal
- Welding of duplex stainless steels calls for controlled welding parameters to achieve specified mechanical and corrosion resistant properties
- Ink jet printing identification on entire length of electrode
- Q2 Lot® - Certificate showing actual wire composition and calculated ferrite number (FN) available online
Typical Applications
- Offshore
- Oil and Gas
- Chemical
- Petrochemical
- Used to weld duplex stainless steels such as (Type 2205)
Welding Positions
- All
Shielding Gas
- 100% Argon
