AVESTA 309L is a high-alloyed 23 Cr 13 Ni wire primarily intended for surfacing of low-alloyed steels and for dissimilar welding between mild steel and stainless steels. AVESTA 309L has a composition that, under normal welding conditions, ensures a crack resistant weld metal with a ferrite content of min. 3%. AVESTA 309L can also be used for welding some high temperature steels. Always consult expertise. AVESTA 309L can also be supplied with a higher Si-content (0.85 %), which provides a somewhat better fluidity and surface appearance.
