Classification

| DIN 8555 / EN 14700 | MF 3-50-CKTZW |
Purpose
- Gas-shielded flux-cored wire for hardfacing hot-work steels, alloyed with Cr-Co-Mo, holding hardness (48–50 HRC) up to 650 °C.
Why it works
The chromium-cobalt-molybdenum combination gives a deposit resistant to creep and to high-temperature oxidation, with good thermal-shock and crack resistance. It work-hardens somewhat in service (up to 53 HRC). Requires M13 (Ar+1%O2) shielding gas.
Fields of application
- Hardfacing of hot-work tool steels: forging dies, hot-shearing tools, punches, rollers.
- Continuous-casting driving rolls, dies, mandrels, forming tools, pumps subject to temperature.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.

Advantages
- Holds hardness up to 650 °C — hot work.
- High resistance to cracking and thermal shock.
- Oxidation- and creep-resistant behaviour.
Limitations
- Needs shielding gas (M13) — not self-shielded.
