Bohler FOX FFB-A description: Rutile electrode, core wire alloyed for analogous, heat resisting rolled steels e.g. in annealing shops, hardening shops, steam boiler construction, the crude oil industry and the ceramics industry. In weld joints exposed to sulphurous gases the final layer has to be deposited by means of FOX FA. Smooth beads and easy slag removal. Scaling resistance up to +1200C. The temperature range between +650 and +900C should be avoided owing to the risk of embrittlement. Thick-walled weldments to be carried out by means of the basic electrode FOX FFB.
