OK Flux 10.16 - All purpose flux for
Ni-based wires and strips
OK Flux 10.16 is an
agglomerated, fluoride basic,
non-alloying flux for submerged
arc welding specially designed
for butt welding and overlay
welding with nickel-based
alloyed wire. Can also be used
for overlay welding with nickelbased
strips. It is primarily used
for multi-run welding of thick
section materials.

OK Flux 10.16 is suitable for
single layer and multi-layer
welding of unlimited plate
thickness and for strip cladding.
It can only be used on DC
current when butt welding with
nickel-based alloy wires. This
flux has good weldability in the
2G/PC position and the well
balanced flux composition
minimises silicon transfer from
the flux to the weld metal
providing good mechanical
properties, particularly good
impact toughness reducing the
risk of hot cracking. It is also
suitable for submerged arc strip
cladding with all grades of
nickel-based strips.
