Lincoln MIG 316LSi Stainless Steel Welding Wire – 0.9mm x 15kg Spool
Product Overview
The Lincoln MIG 316LSi 0.9mm x 15kg is a premium low-carbon, silicon-alloyed stainless steel MIG welding wire engineered for high-performance GMAW (Gas Metal Arc Welding) applications on molybdenum-bearing austenitic stainless steels. Classified under AWS A5.9 ER316LSi / EN ISO 14343-A G 19 12 3 L Si, this wire delivers superior corrosion resistance, smooth arc characteristics, and excellent weld bead wetting — making it the go-to choice for fabricators working in demanding, corrosive environments.
Supplied on a convenient 15kg spool in a precise 0.9mm diameter, this wire is ideal for semi-automatic and robotic MIG welding of medium-to-heavy gauge stainless steel components, offering extended run times and fewer spool changes for improved productivity on the shop floor.
Key Features & Benefits
- Low Carbon (L) Content – Minimizes carbide precipitation and sensitization at the weld zone, reducing the risk of intergranular corrosion, especially important when welding thicker sections or performing multi-pass welds.
- Silicon (Si) Enhanced Formulation – Improves puddle fluidity and bead wetting action, resulting in a smoother, flatter weld bead with reduced spatter and easier slag/oxide removal.
- Molybdenum Alloying – Provides enhanced resistance to pitting and crevice corrosion, particularly in chloride-rich and acidic environments.
- Consistent Wire Feeding – Precision-layer wound on a 15kg spool for smooth, uninterrupted feeding, minimizing birdnesting and arc interruptions.
- Stable Arc Performance – Enables higher travel speeds, excellent tie-in at bead edges, and consistent penetration across a wide range of welding parameters.
- Bright, Uniform Wire Surface Finish – Reduces contact tip wear and ensures reliable conductivity for consistent arc starts.
