AWS A5.23 F8A10-ENi2-Ni2 welding fulx xiang welding is a fluoride-basic flux with high basicity and low impurity levels such as P and S. It is suitable for welding on DC and AC using single and tandem wire process.
It also specially suited to narrow gap welding on AC. it provide excellent weld-ability and due to neutral behavior, high mechanical properties of weld metal can be controlled by using the appropriate wire grade.
- Fine grain structural steels for low temperature requirements.
Offshore applications. High tensile fine grain steels.

Notes on usage:
1. Flux exposed to atmosphere for an excess period must be re-baked at 300-350℃ for 2—4hr holding time. 2. Re-circulation of flux should be limited to three cycles. After this, the flux should be mixed with twice its volume of new flux prior to further use.
3. We recommend using heated hoppers for storage of flux in production.
