General description:

NST A-309L is a rutile flux cored wire for positional welding of corrosion resistant materials such as AISI 304 etc. against carbon steel. The flux cored wire uses an Argon/CO2 mixed shielding gas. This ensures a user friendly and stable welding arc, less spatter, good visual bead appearance and smooth transition to the parent materials. The newly developed slag system gives the welder better control of the weld pool and this wire can now be welded without weaving in all positions. It is also suitable for use with ceramic backing for single sided welding. NST A-309L’s chemical composition ensures a weld metal equivalent of AISI 304 in the first layer of a cladding process.
