Solid Wire Electrode BA-WIRE 307Mod for Submerged Arc Welding
Classification:
EN ISO 14343-A: S 18 8 Mn
SFA 5.9 / AWS A5.9: ER(307)
Main Application
Wire electrode for submerged arc welding intended for weldingwork-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-WIRE 307Mod is similar to ER 307 type with increased manganese content (≈ 7.0%), reducing the risk for hot cracking.

Base Materials
Dissimilar joints, buttering and intermediate layers before hard overlays.
Steels with manganese content up to 14%, steels with 13 - 17% chromium content.
Suitable fluxes: BF 38, WP 380
Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.
