StarBlaze MIG 308LSi
AWS A5.9: ER 308LSi | EN ISO 14343-A: G 19 9 L Si
StarBlaze MIG 308LSi is an extra-low carbon stainless steel MIG wire with enhanced silicon content, designed for welding austenitic stainless steels such as AISI 301, 302, 304, 304L, 308, and 308L. With a Cr/Ni composition of 20Cr/9Ni and silicon levels around 0.80%, it delivers excellent weldability, arc stability, and bead appearance. The wire is ideal for food processing, chemical equipment, piping, and boiler fabrication. Precision layer-wound and processed for smooth feeding and minimal spatter, it performs reliably across all welding positions.
