Classification
| AWS class | E308-26 |
|---|---|
| EN ISO class | E 19 9 R 53 |
Purpose
- High-output rutile electrode (~150% efficiency) for 18/8 Cr-Ni steel (~E308-26 / E 19 9 R 53), flat and horizontal-fillet only.
Why it works
Heavy high-output rutile coating — deposits roughly 150% of the core-wire weight, built for flat/horizontal-fillet production welding on 18/8 stainless and carbon steels, not for all-position work.
Fields of application
- Joint and surfacing welds on 18/8 Cr-Ni steel, high-strength tempered steels, stainless steels and carbon steels.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.
Advantages
- ~150% deposition efficiency.
- High-current capable.
- Weldable on DC+ or AC.
Limitations
- Flat and horizontal-fillet position only (PA/PB).
