MIG-2209																	Classifications: YB/T5092 H022Cr20Ni9Mo3N AWS A5.9 ER2209 AWS A5.9M ER2209 ENISO14343-A:G(22 9 N L) ENISO14343-B:SS2209
MIG Wire for Stainless Steel
(Austenitic-Ferritic Duplex Alloy)
Application:
MIG-2209 is designed to weld duplex stainless steels such as 2205 (UNS Number N31803). High tensile strength and improved resistance to stress corrosion cracking and pitting characterize the welds of this wire. This wire is lower in ferrite compared to that of base metal in order to obtain improved weldability.
Characteristics:
1. The welds offer excellent resistance to stress corrosion, cracking and pitting; 2.The microstructure of the weld metal consists of austenite and ferrite; 3.Welding of duplex stainless steels calls for controlled welding parameters to achieve specified mechanical and corrosion resistant properties; 4.Ink jet printing identification on entire length of electrode.
Polarity:
DC+

Notes on usage:
1. Shielding gas: 98% Ar + 2% O₂; 2.Shielding gas flow rate: 20-25 l/min; 3.Wire stick-out: 15-25 mm; 4. Interpass temperature: ≤150℃; 5. Prior to welding, base metal surfaces should be cleaned of grease, oil and corrosion contamination; 6. Take proper protection against wind to prevent blowholes when welding outdoors.
