Classification

| DIN 8555 / EN 14700 | MF 10-GF-55 G |
Purpose
- Self-shielded flux-cored wire (open arc) with chromium carbides, 58–62 HRC, for severe abrasive wear.
Why it works
Chromium carbides in a eutectic matrix give very high abrasion-oriented hardness. Transverse stress-relief cracks in the bead are normal and do not impair function. Open arc, no gas.
Fields of application
- Bucket teeth and excavator buckets, brick-press springs, fan blades, drills, mixers and blades, grinding/pulverising rolls and table segments, wear plates.
- Clad pipe, dredge-pump shells and related components, hammers.

Advantages
- 58–62 HRC — severe abrasion.
- No gas needed — open arc.
- Chromium carbides, high wear resistance.
Limitations
- Maximum two passes with this wire.
- Transverse cracks in the bead are normal (do not impair function).
- Machinable only by grinding.
