Purpose
- Flux-cored wire (FCW) counterpart to FERVEO HTS 690 MIG, for the same high-elastic-limit steel (AWS E110T15-M21A8-K4-H4, EN ISO T69 6 Mn2NiCrMo MM 1H5).
Why it works
Same base-metal coverage as FERVEO HTS 690 MIG (Weldox 700, BSC RQT 701 and N-A-XTRA equivalents), in flux-cored wire form instead of solid wire — weldable in all positions.
Fields of application
- High-elastic-limit Cr-Ni-Mo steel at the same strength level as FERVEO HTS 690 MIG, welded by semi-automatic or automatic process with gas shielding.

Advantages
- Weldable in all positions, unlike many solid wires of equivalent strength that are restricted to favorable positions.
- Same base-metal coverage as FERVEO HTS 690 MIG, in flux-cored form.
Limitations
- For the same grade in solid-wire form, see FERVEO HTS 690 MIG.
