flux-cored wire (FCW)Catalogue only
AWS class
E 70 T-5M
EN ISO class
T 42 A Z B M 3
Tensile strength (Rm)
500–640 MPa
Classification
| AWS class | E 70 T-5M |
|---|---|
| EN ISO class | T 42 A Z B M 3 |
Purpose
- Basic-type flux-cored wire specific to Armco iron and galvanized steel (AWS E 70 T-5M, EN ISO T 42 A Z B M 3).
Why it works
A very-low-carbon composition tuned specifically to Armco iron, suited to galvanized tanks where other general-purpose flux-cored wires aren't manufacturer-qualified.
Fields of application
- Welding of Armco iron and mild steel, including galvanized tanks made of Armco iron, suited to automation.

Advantages
- Specific application on Armco iron and galvanized tanks, a niche not covered by the rest of the FERVEO STL FCW range.
- Suited to automated welding.
Limitations
- Specifically intended for Armco iron — for general construction steel, see FERVEO STL 480 B M FCW.
