Avesta 309L Stainless Steel Electrodes

Rutile coated electrode of E 23 12 L / E309L-17 type primarily intended for surfacing low-alloyed steels and for dissimilar welds between mild steel and stainless steels. Can also be used for welding some high temperature steels, such as 1.4833 / ASTM 309S. Results in an austenitic all-weld metal microstructure with ~15% ferrite. The corrosion resistance is superior to E 19 9 L / E308L fi llers. When used for overlay welding on mild steel a corrosion resistance equivalent to that of 1.4301 / 304 is obtained already in the fi rst layer. Suitable for service temperatures from –60ºC to 300ºC and for weld claddings up to 400ºC. The scaling temperature is approximately 1000ºC in air.
