Avesta S 309L S / Avesta C 807 is a wire-flux combination for submerged arc welding. The wire is a high-alloy 23 Cr 12 Ni primarily intended for dissimilar welding between stainless and mild steel and for surfacing low-alloy steels, offering a ductile and crack resistant weldment.

Avesta C 807 is an agglomerated basic welding flux for welding stainless high alloyed CrNi (Mo) steels. The weld seam are smooth and finely rippled without any slag residues. Besides the good slag detachability, the flux also provides good fillet weld properties. The weld metal show high degree of purity and good mechanical properties even at cryogenic temperaturess.
