Application / Properties:
Electrode for producing
crack- free and tough
welding joints, Weld metal
recovery is approx. 115%
Smooth and clean welds
blending into base metal
without undercut. Good gap
bridging properties. Welds
are X-ray quality. Suitable
for depositing layers on
steels having a higher
carbon content (up to 0.4)
