AWS A5.22 E309LT1-1, ISO 17633-A-T 23 12 L P C1 1

Diameter: 1.2, 1.4, 1.6mm.

AWS A5.9 ER309LT1-1 is a CO2 gas shielded stainless steel flux-cored welding wire. it has excellent welding performance with soft and smooth arc, low spatter level, effortless slag removal ability and optimal bead apperance. It is permitted for all position welding. The deposit metal has good crack resistance.

The product is applicable for welding 06Cr23Ni13(S30908), stainless steel and carbon steel base metal, such as 309 stainless steel, and can be used for the same type of stainless steel structure, composite steel, dissimilar steel and other components manufactured by synthetic fiber and petrochemical equipment. It is mainly used in the fields such as etrochemical industry, food and medical treatment, ships, muclear power and so on.
