Product Overview

  • 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.
