Propriétés

Smooth drop transfer and more stable arc compare to solid wires. High productivity and weldabillity, better wetting properties compared to solid wires. Ductile weld metal quality and X-ray soundness and ferrite level between 30 and 50 (FN). Excellent for use in down hand welding. Excellent against pitting and stress corrosion. The PREN above 35 weldmetal offers outstanding resistance against pitting.
