Typical weld metal chemical composition (%), DC+
OK Flux 10.80 is an
agglomerated, neutral-basicity
flux for submerged arc welding.
It alloys a lot of Si and Mn to
the weld metal and thus is
suited for single and limited
pass butt welds and for
surfacing tasks.
It is welded with single and
multi-wire procedures, with
either DC or AC current. Due to
the high alloying the flux is
intended for plate thickness up
to approximately 20mm in
joining applications.
OK Flux 10.80 is used in
general construction, pressure
vessel industries and others. It
is appreciated for surface buildup
jobs such as the repair of
diesel engine pistons, because
hardness of the weld metal is
increased due to the high
alloying.
