Features and Applications
- ELIFLUX BFF 30 is a fluoride-basic neutral flux with high basicity and low impurity levels such as P and S.
- As a result of low oxygen levels in the weld deposits uniform mechanical properties with high toughness values at low temperature are achieved.
- Designed for multi wire application where high deposition rate as well as good slag removal is required this flux shows excellent weldability and weld bead appearance.
- ELIFLUX BFF 30 is suitable for welding on D.C. and A.C. using single, tandem and Multi-Wire processes.
- Process requirement of re-drying at 300°C - 350°C for 2 hours
