Solid Wire Electrode BA-MIG 309LNb for MIG/MAG Welding

Classification:
EN ISO 14343-A: G 23 12 Nb
SFA 5.9 / AWS A5.9: ER(309LNb)

Main Application

BA-MIG 309LNb is a solid wire electrode for GMAW, niobium-stabilized similar to BA-MIG 309L with the addition of Nb. Suitable for overlay carbon and low-alloy steels, when a type 347 overlay is required.
