MIG
Solid Wire Electrode BA-MIG 309L for MIG/MAG Welding
Classification:
EN ISO 14343-A: G 23 12 L
SFA 5.9 / AWS A5.9: ER309L
Main Application
BA-MIG 309L is a solid wire electrode for GMAW 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
