MIG-347L/ER347L

MIG-347L													Classifications: YB/T5092 H022Cr20Ni10Nb AWS A5.9 ER347L AWS A5.9M ER347L ENISO14343-A:G(19 9 Nb) ENISO14343-B:SS347L
MIG Wire for Stainless Steel
(Low Carbon Stabilized Austenitic Alloy)
Application:
For joining stabilized 19Cr-11Ni-Nb (SUS347)or 18Cr-9Ni-Ti(SUS321)grade stainless austenitic steels commonly used in petrochemical facilities, pressure vessels, food and medicalequipment,etc.
Characteristics:
1. Increased content of niobium decreases the likelihood of intergranular chromium carbide precipitation and therefore vulnerability to intergranular corrosion; 2.Excellent wire feedability, stable arc, less spattering, good bead appearance.
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.
