MIG Wire for Stainless Steel
(Austenitic-Ferritic Duplex Alloy)
Применение:
For joining 25Cr type austenitic-ferritic duplex stainless steel alloys, such as SUS2507 used in petrochemical industry, marine engineering, etc.
Характеристики:
1. Weld deposits have an austenitic-ferritic (duplex) matrix with ferrite content as high as 40%. With pitting resistance equivalent(PRE) ≥40, the weld deposits have excellent corrosion resistance especially to pitting, crevice and stress corrosion cracking; 2. Excellent wire feedability, stable arc, less spattering, good bead appearance.

Замечания по использованию:
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.
