SFA 5.9 / AWS A5.9: ER(307)

Characteristics and Application

 AWS A5.9: ER(307) is a solid wire rod for GTAW, 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. AWS A5.9: ER(307)Si is similar to ER 307 type with increased manganese content (≈ 7.0%), reducing the risk for hot cracking.
