TOKO AWS A5.4 E309L-16 welding rods are helpful for use in positions that require welding of mild steels and low alloys, such as 304L and 347. They are also recommended for joining of dissimilar steels such as 301 and 304, for joining stainless steels to mild or carbon steels, for buildup and repair on surface flaws, and for overlays in mildly corrosive atmospheres..

You can weld the dissimilar metals for the stainless steel overlays or plain carbon or low alloy steel. The E309L-16 is preferred for the cladding over carbon or low alloy steel and this also provides a very good finish with the dissimilar joints which undergo heat treatment. The E309L-16 is used for the welding of the low carbon and the low alloy stainless steels.

The E309-16 is the alloy which is primarily intended for the welding heat-resistant austenitic chromium-nickel steels of the similar analysis. This is also good in case of the dissimilar welding of stainless steel to mild steel and also the welding surfaces of the steel. The maximum temperature for the welding process with this electrode cannot be greater than 700 degrees Fahrenheit or 370 degree Celsius. This is having a greater use in the industrial and general fabrication process.

Features of E309L-16

  • Designed with low carbon levels to help eliminate carbide precipitation in high temperature service
  • Designed for joining stainless steel to mild or low alloy steel
  • Flux coating provides smooth arc transfer and slag is self-peeling for easy removal

Typical Applications

  • Joining stainless steel to mild or low alloy steel
