Classification
| AWS class | E 309LT0-1/-4 |
|---|---|
| EN ISO class | T 23 12 L R C/M 3 |
| Other standards | ISO 20172: Gruppe 8.1 |
Purpose
- Low-carbon Cr-Ni 23/13 metal-cored flux-cored wire, for joining highly alloyed materials — service to 300°C, scaling-resistant to 1000°C.
Why it works
Same 309L class as the rest of the family, in metal-cored form — the 1000°C scaling resistance matches the basic INX 309 electrode, useful for dissimilar-steel joints that will also run hot.
Fields of application
- Joining of highly alloyed materials: DIN 1.4301, 1.4713, 1.4724, 1.4828, 1.4878.
- Joining of dissimilar steel types.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.
Base metals
1.43011.47131.47241.48281.4878
Advantages
- Resistant to scaling up to 1000°C.
- Continuous service up to 300°C.
Limitations
- High ferrite content in the deposit: risk of sigma-phase embrittlement under sustained exposure at 600–900°C — not recommended for critical structures in that range.
