MIG
Solid Wire Electrode BA-MIG 307Si for MIG/MAG Welding
Classification:
EN ISO 14343-A: G 18 8 Mn
SFA 5.9 / AWS A5.9: ER(307)
Main Application
BA-MIG 307Si is a solid wire electrode for GMAW, intended for welding work-hardenable steels, armor steel and austenitic stainless manganese steels. Also suitable for joining stainless chromium steels with chromium content up to 18% and overlay welding of mild steels and low-alloy steels. BA-MIG 307Si is similar to ER 307 type with increased manganese content (≈ 7.0%), reducing the risk for hot cracking.
