Specifications:
- AWS/ASME SFA A5.4 : E 309L-16
- EN ISO 3581-A-E 23 12 L R 12
Description and Application
- Rutile coated low carbon electrode for joining of dissimilar steels (austenitic steels to mild and low alloy steels).
- Suitable for welding similar metal joints (23% Cr- 12% Ni) and austenitic – martenistic steels of 13% Cr – 6% Ni type.
- Used for buffer layers in hard facing applications.
- Focused and stable arc. Easy slag release.
