SW-309L Cored
FLUX CORED WIRE
AWS A5.22 / ASME SFA5.22 E309LT1-1/-4
JIS Z3323 YF309LC
l Applications
SW-309L Cored is designed for the welding of dissimilar metals such as stainless steel and carbon steel or stainless steel and low alloy steels.
l Characteristics on Usage
SW-309L Cored is a flux cored wire for all position welding to be used with CO2 or 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.
l Notes on Usage
a) Use with 100% CO2 or Ar + 20~25% CO2 gas.
b) Refer to page 168 for storage instructions and notes on usage.
