General description:

NST 309MoLT is a flux cored wire for flat position (PA) and fillet welding (PB and PC) of stainless steel materials such as AISI 316 and similar against carbon steel. The wire is also suitable for cladding of carbon steel where a Mo stainless cladding is needed. 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. NST 309MoLT has a slag freezing system which is slightly slower than wires designed for positional welding. This makes this wire suitable for flat position and fillet welds. It is also suitable for use with ceramic backing for single sided welding.
