Classification

| EN ISO class | T 46 2 Mo M M 3 |
Purpose
- Ar+CO₂-shielded rutile molybdenum flux-cored wire, low carbon (0.5% Mo, AWS E80T1-A1M, EN ISO T 46 2 Mo M M 3) — semi-automatic welding of low-alloy molybdenum steels, flat and horizontal-fillet position only.
Why it works
The same molybdenum base alloy as FERVEO CMO Mo R C FCW, with lower carbon and silicon, an Ar+CO₂ gas mix instead of pure CO₂, and a narrower position range (flat and horizontal fillet) — built for mechanized shop welding of plate and pipe, not for all-position work.
Fields of application
- Mechanized shop welding of low-alloy molybdenum steel plate and pipe, flat or horizontal-fillet position.

Advantages
- Certified cold toughness (tested at -20°C).
- Low carbon and silicon — a cleaner deposit for precision mechanized welding.
Limitations
- Flat and horizontal-fillet position only — unlike FERVEO CMO Mo R C FCW, which covers more positions.
- Needs shielding-gas (Ar+CO₂ mix) equipment — not self-shielded.
