Description
The ER316L 3.2mm Sub Arc Wire 25kg offers reliable performance in stainless steel welding where corrosion resistance is a top priority. This wire is specifically designed for submerged arc welding (SAW) of 316 and 316L stainless steel. It works especially well in environments exposed to chlorides, moisture, or aggressive chemicals.
Because it contains molybdenum, this wire provides enhanced resistance to pitting and crevice corrosion. Its low carbon content also helps prevent carbide precipitation during welding. That means your finished welds remain strong and corrosion-resistant—even under extreme service conditions.
Welders prefer the 3.2mm diameter for its smooth feeding and excellent arc stability. It produces clean, even weld beads with minimal spatter. As a result, post-weld cleanup is quicker, and overall job efficiency improves. The 25kg spool gives you more wire for longer weld runs, reducing the need to stop and change reels.
Industries such as marine fabrication, food processing, petrochemicals, and pharmaceuticals often rely on ER316L sub arc wire. That’s because it delivers durability in both high-moisture and chemically harsh environments. Whether you’re welding tanks, piping, or vessels, you can trust this wire to hold up.
You can use this wire with DC+ current and standard SAW systems. It performs well in both automatic and semi-automatic setups, giving you flexibility on any project.
