OK Flux 10.90 – Flux for 9% Ni<br />
and Ni-based alloys reducing<br />
the risk of hot cracking<br />
OK Flux 10.90 is an<br />
agglomerated, fluoride basic<br />
flux for submerged arc welding<br />
of 9% nickel steels, other high<br />
alloyed steels and nickel-based<br />
alloys, using nickel-based<br />
wires. It is primarily used for<br />
multi-run welding of thick<br />
section materials.<br />
It can be used for single layer<br />
and multi-layer welding of<br />
unlimited plate thickness for<br />
butt and fillet welds and works<br />
very well on DC current. The<br />
flux gives a good bead shape,<br />
and good slag detachability<br />
and also very good weldability<br />
in the 2G/PC position. The low<br />
Si addition during welding<br />
provides good mechanical<br />
properties, particularly good<br />
impact toughness. It is a<br />
chromium compensating flux,<br />
adding manganese and slightly<br />
adding nickel. This minimises<br />
the risk of hot cracking, when<br />
welding with Ni-based<br />
consumables.<br />
LNG storage tanks are welded<br />
with OK Flux 10.90 because of<br />
its good mechanical properties<br />
and, very importantly, the<br />
reduction of hot cracking risks.<br />
It is also used for welding of<br />
components of chemical and<br />
petrochemical plants, offshore<br />
constructions and pressure<br />
vessels.<br />
