AWS/ASME A 5.4 E 309L - 16
EN: E23 12 LR 32
ISO 3581: E23 12 LR 32
FEATURES & APPLICATIONS |
Wherever maximum ductility is required when joining dissimilar steels to themselves or to stainless steels.
- Extra strong and tough stainless steel electrode for joining steels to stainless steels.
- Highly recommended for joining hard to weld steels.
- Moisture resistant coating provides sound porosity free deposits.
- Slag is self removing.
