ER 308LSi Welding wires

​ER 308LSi welding wire is a type of stainless steel welding wire designed for welding 18-8 austenitic stainless steels such as 304L and similar grades. The “L” in ER 308Lsi indicates a lower carbon content compared to standard ER308, promoting better weldability and minimizing the risk of carbide precipitation. The “si” signifies the addition of silicon to improve wetting and fluidity during welding.
