Purpose

  • Self-shielded, heavily alloyed wire (C-Cr-Mo-Nb-W-V) forming extremely hard carbides — for extreme abrasive mineral wear, heat-resistant to 800°C.

Why it works

The structure solidifies mainly as eutectic Cr carbides plus Nb-Mo-W-V carbides — the combination gives the highest wear resistance in the self-shielded HRF FCW family. Hot-hardness loss is minimal: ≈4% at 400°C and ≈10% at 700°C, holding resistance to 800°C.

Fields of application

  • Sintering plants, augers, blast-furnace bells.

Advantages

  • Very high hardness (63-65 HRC).
  • Minimal hot-hardness loss (≈4% at 400°C, ≈10% at 700°C, resists to 800°C).
  • No shielding gas needed.

Limitations

  • Current set by diameter: from 160-260 A (1.6 mm) up to 320-400 A (2.8 mm).
