Purpose
- Molybdenum-alloyed metal-cored wire, for elevated-temperature service (AWS E80C-GMH4, EN ISO 17632-A T46 2 Mo MM 1 H5) — the only Mo-alloyed reference in the FERVEO STL ladder's general FCW range.
Why it works
Mo alloying, unusual in a general-purpose flux-cored wire, extends service into moderately elevated temperatures — the same alloying principle as the FERVEO CMO/SAW family, but in metal-cored form for carbon steel that isn't properly heat-resisting.
Fields of application
- Carbon-steel fabrication with elevated-temperature service, up to around 550°C, in all positions.

Advantages
- Elevated-temperature service (up to around 550°C), a niche not covered by the rest of the FERVEO STL ladder's general FCW range.
- High yield, good operating behavior, no slag or spatter.
Limitations
- For more demanding heat-resisting service (Cr-Mo grade P11/P22/P5/P91), see the FERVEO CMO ladder.
