MasterWeld 2209 is used to weld duplex stainless steels.
These are typically austenitic-ferritic stainless alloys of the 22% Cr, 5% Ni, 3% Mo types (Type 2205). 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.
Applications: Offshore, Oil and Gas, Chemical, Petrochemical
