MIG
Solid Wire Electrode BA-MIG 309LSi for MIG/MAG Welding
Classification:
EN ISO 14343-A: G 23 12 LSi
SFA 5.9 / AWS A5.9: ER309LSi
Main Application
BA-MIG 309LSi is a solid wire electrode for GMAW with higher Si content than BA-MIG 309L, suitable for joining stainless Cr-Ni steels type 309, Cr-steels and dissimilar steels like austenitic stainless steels to mild or low-alloyed steels, buffer layers and overlays on C-Mn, mild steel or low alloy steels and for joining 304L/321. Also recommended for welding 12% Cr ferritic steels.
