INTERNATIONAL SPECIFICATIONS

AWS/ASME A 5.4:E312-17 DIN 8556: E 29.9 R 23

NFA 81-343: EZ 29.9 R 23EN 1600: E 29.9 R 3 2 ISO 3581: E 29.9 R 23

Due to exceptional strength and crack resistance, it is ideal for repairing tools, dies, spring steel and any dissimilar metal combinations, except for aluminum and copper alloys. It is also recommended for repairing worn

parts and as an underlay for hardfacing.

RECOMMENDED FOR:

A duplex austenite/delta ferrite structure with a Shaeffler ferrite value below 35%.

The area in which the weld is to be made should be free of rust, grease & grit, paint and other materials

owhich cause weld contamination. A 90 vee joint

should be used when joining heavy sections. Maintain a short arc length and use stringer beads.
