KEY FEATURES • TIG/GTAW rod for weathering steels. • Weathering steels, with controlled additions of Cu, provide improved corrosion resistance compared to CMn steels. • The improved resistance to atmospheric corrosion means these steels find use for architectural applications and also for welding CMn steels to prevent preferential corrosion of the weld.
STANDARDS • EN ISO 636-A: W 42 4 Z • AWS A5.28: ER80S-G
