Classification

|---|---|
| EN ISO class | T Fe 16 |
| DIN 8555 / EN 14700 | MF 10 GF 65 GT |
Purpose
- Self-shielded flux-cored wire with complex carbides (Cr-Nb-Mo-W-V), 63–65 HRC, for abrasion at high temperature up to 650 °C.
Why it works
High density of primary chromium carbides with multiple secondary Mo, Nb, W and V carbides: retains hardness at temperature and resists high-stress sliding abrasion. Designed for one or two passes. Stress-relief cracks are normal and do not reduce wear resistance. Self-shielded.
Fields of application
- Clad wear plate, slurry pipe, cement-furnace components.
- Sinter-plant parts, fan and mixer blades, screws.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.
Base metals
Clad wear plate, slurry pipe, cement furnace components, sinter plant parts, fan blades, mixer blades, screws
Advantages
- Holds hardness up to 650 °C.
- Complex Cr-Nb-Mo-W-V carbides — high-stress abrasion.
- No gas needed — self-shielded.
Limitations
- Designed for one or two passes.
- Stress-relief cracks are normal (do not reduce wear resistance).
- Machinable only by grinding.
