SW-309L Cored is designed for the welding of dissimilar metals such as stainless steels and carbon steels or stainless steels and low alloy steels.
Characteristics on Usage
SW-309L Cored is a flux cored wire for all position welding to be used with CO₂or Argon + CO₂ mixed shielding gases. This wire contains a high ferrite level in its austenitic structure thus providing better weldability together superior heat and corrosion resistance. As larger amounts of alloying elements are added, it becomes suitable for the welding of dissimilar joints where dilution from ferrite steel takes place.
