Welding wire Lincoln LNM 309LSi - 1.2mm

The welding wire Lincoln LNM 309LSi contains approximately 12% delta ferrite, providing resistance to hot cracking.  The type is ER309LSi / G 23 12 L Si. With increased silicon content, the fluidity of the weld pool improves along with its wetting ability, resulting in a smooth weld bead surface with a regular shape. This wire can also be used for welding coated steels operating at temperatures up to 300°C. The main applications of this wire include general manufacturing, transportation, and processing industries. During welding with LNM 309LSi wire, it is recommended to use a shielding gas mixture containing argon ranging from 0.5% to 5% CO₂ or from 0.5% to 3% O₂ as the shielding gas.
