Welding wire MIG 316LSi 1.2 mm / 12.5 kg D300 MIG/MAG

ER 316LSi solid wire for MAG welding of austenitic stainless steels.

This austenitic wire has a very low carbon content and is suitable for welding corrosion-resistant steels. Recommended for exposure to general and intergranular corrosion in acidic and chloride environments. The increased Si content improves welding properties. Used in structures in the chemical, food, and shipbuilding industries, as well as for architectural components.

The 316LSi designation indicates that this wire has a low carbon (L) content and additional silicon (Si), which facilitates smooth, strong welds. This makes 316LSi wire ideal for applications where aesthetics and weld durability are key.
