Oerlikon Fluxinox 309L PF description: FLUXINOX 309L-PF is an alloyed rutile flux cored wire for joining high-alloyed Cr and Cr-Ni-(Mo) steels to unalloyed steels, as well as for depositing austenitic stainless cladding. The highest operating temperature for dissimilar joints is 300C. The weld metal is non-scaling up to 850C. Preheating and interpass temperatures should be calculated according to the base metal used. FLUXINOX 309L-PF exhibits outstanding, almost spatter-free, welding properties and produces finely rippled flat and smooth welds which are free of undercut. Very easy slag removal. Due to its fast-freezing slag, FLUXINOX 309L-PF is used for welding in the horizontal (PD), overhead (PE) and vertical-up (PF) positions.
