Classification
| AWS class | E 111 T1 - GC |
|---|---|
| EN ISO class | T 69 4 Mn2.5Ni P C 1 |
Purpose
- Top-step rutile flux-cored wire in the range, for low-alloy, high-strength naval/structural steel (AWS E 111 T1-GC, EN ISO T 69 4 Mn2.5Ni P C 1).
Why it works
The highest mechanical-strength and alloy step in the entire FERVEO HTS FCW range, with an especially smooth and stable low-spatter arc — built for single- and multi-pass welding of high-responsibility naval steel.
Fields of application
- Low-alloy, high-strength naval and structural steel (HY-80, HY-100 and equivalents), single- and multi-pass welding.

Advantages
- The highest mechanical-strength step in the entire FERVEO HTS FCW range.
- Especially smooth and stable arc, with low spatter, in single- and multi-pass welding.
Limitations
- For lower-strength duty, the FCW range offers intermediate steps (FERVEO HTS 460/550/620 FCW) at a lower alloy cost.
