Characteristics and typical fields of application
Avesta 309L is a high-alloy low carbon electrode designed for welding dissimilar joints between stainless and mild or low-alloy steels. The electrode is well suited as a buffer layer when overlay welding on mild steels, providing an 18 Cr 8 Ni deposit from the first layer. Avesta 309L can also be used for welding some high temperature steels, such as 1.4833/ASTM 309S. Corrosion resistance: Superior to 308L. When used for overlay welding on mild steel a corrosion resistance equivalent to that of 1.4301/ASTM 304 is obtained already in the first layer.
