Oerlikon Fluxinox 307 PF description: FLUXINOX 307-PF is an alloyed rutile flux cored wire with a fast-freezing slag for crack-resistant joining and surfacing of heat treatable steels, armour plates, corrosion resisting steels and high manganese steels. It is also suitable for joining austenitic stainless steels to unalloyed steels. The weld metal is suitable for operating temperatures up to 300C, and is non-scaling up to 850C. It is highly rust and corrosion resistant, and will harden by cold working. Due to its fast-freezing slag, FLUXINOX 307 PF is well-suited for welding in the horizontal (PC), overhead (PE) and vertical-up (PF) positions.
