BÖHLER FOX FFB-A Stick electrode
Classifications high-alloyed
EN ISO 3581-A: AWS A5.4:
E 25 20 R 3 2 E310-16
Characteristics and field of use
Core wire alloyed, rutile coated stick electrode for same-type, heat-resistant rolled steels such as
in annealing shops, hardening shops, steam boiler construction, the petrochemical industry and
the ceramic industry. The final layer of joints that are exposed to reducing gases containing sulphur
must be welded with BÖHLER FOX FA. The BÖHLER FOX FFB basic stick electrode is preferable
for thick-walled welded constructions. Smooth seams and easy slag removal. Resistant to scaling
up to +1200°C. Due to the risk of embrittlement, the temperature range between +650-900°C
should be avoided.
