Description
The ER309L 3.2mm Sub Arc Wire 25kg is a reliable choice for submerged arc welding (SAW) where joining dissimilar metals is required. Welders across South Africa trust ER309L wire for stainless steel-to-carbon steel applications, thanks to its high resistance to cracking and intergranular corrosion. Its low carbon content (the “L”) ensures superior corrosion protection, even in high-temperature environments.
This 3.2mm stainless steel wire is well-suited for welding thick sections and heavy-duty structural components. It delivers a smooth and stable arc with minimal spatter, making post-weld clean-up fast and efficient. Whether you’re working on piping, chemical tanks, or power generation systems, this wire helps you achieve consistent weld integrity and high-quality results.
The 25kg spool offers extended welding time without interruptions, increasing productivity in fabrication shops and industrial settings. ER309L wire performs best on DC+ current and works exceptionally well with both automated and manual SAW equipment.
One of the key advantages of this wire is its high ferrite content. This improves hot cracking resistance and adds strength to welds under high stress. With the 3.2mm thickness, you also benefit from deeper weld penetration on thick materials. If you require precision, strength, and longevity, this wire delivers on all fronts.
