Avesta 309L-3D Electrodes for Stainless and Unalloyed Steels
AVESTA 309L-3D is an over-alloyed electrode intended for welding stainless steel to unalloyed or low-alloy steels.
It has a thin,rutile-acid type coating and is designed for welding with either AC or positive polarity DC.
It has a composition that, under normal welding conditions, ensures a crack resistant weld metal.
This electrode can also be used for welding some high temperature steels.
Superior to 308L when surfacing mild steel a corrosion resistance equivalent to that of ASTM 304 is obtained already in the first bead.
