OK Flux 10.93 – ESAB’s number<br />
one for stainless steel and<br />
dissimilar joints<br />
OK Flux 10.93 is an<br />
agglomerated, fluoride basic flux<br />
for submerged arc welding of<br />
stainless steels. It is used for<br />
single run and multi-run welding<br />
of all plate thicknesses giving<br />
excellent welding characteristics.<br />
It can be combined with a wide<br />
range of stainless wires and is<br />
commonly used for butt and fillet<br />
welding of all standard austenitic<br />
and higher alloyed stainless<br />
steels.<br />
The flux works very well on DC<br />
current and has good weldability<br />
in the 2G/PB position. It provides<br />
a very good slag detachability, a<br />
smooth surface finish and a nice<br />
bead appearance. The low Si<br />
addition during welding provides<br />
good mechanical properties with<br />
particularly good impact<br />
toughness properties.<br />
OK Flux 10.93 is one<br />
of the most commonly used<br />
fluxes for welding stainless and<br />
corrosion resistant steels. It is<br />
well established in chemical<br />
and petrochemical plants,<br />
offshore construction, pressure<br />
vessels, storage tanks,<br />
chemical tankers, power<br />
generation, nuclear, pulp and<br />
paper, civil constructions and<br />
transport industries. This is a<br />
flux particularly well suited for<br />
the joining of duplex 2205<br />
stainless steels, for example in<br />
chemical tankers.<br />
