Description
The ER2209 Sub Arc Wire 3.2mm 25kg spool is engineered for high-performance welding of duplex stainless steels, such as UNS S31803 and S32205. This wire offers excellent strength, superior corrosion resistance, and great weldability—making it a top choice in demanding industries.
Use ER2209 Sub Arc Wire when welding components exposed to chloride environments, chemical processing, seawater, and aggressive media. It’s commonly used in pressure vessels, tanks, heat exchangers, and pipelines, where stress corrosion cracking and pitting resistance are critical.
The 3.2mm diameter ensures high deposition rates, making it ideal for heavy fabrication and long weld seams. When used in submerged arc welding (SAW) processes, this wire delivers excellent arc stability, clean slag removal, and smooth bead appearance. Combine it with a suitable SAW flux to achieve top mechanical and corrosion-resistant results.
This duplex-grade filler wire creates welds that match the base metal’s mechanical strength and corrosion resistance. The balanced ferrite-austenite microstructure also improves resistance to cracking and high-temperature scaling.
