63181200 - Bonarc ER316L Stainless Steel TIG Welding Rod 0.045 Inch 5kg

Premium ER316L Stainless Steel TIG Filler Metal

The Bonarc ER316L TIG Rod (.045" diameter) is a high-performance austenitic stainless steel welding consumable packaged in a convenient 5kg tube. Engineered to meet AWS A5.9 specifications, this filler metal is specifically designed for joining Type 316 and 316L base metals. The primary distinction of the ER316L alloy is the addition of Molybdenum (Mo), which significantly enhances the weld deposit's resistance to pitting and crevice corrosion, particularly in chloride-containing environments.

This rod features an extra-low carbon content (denoted by the 'L'), limiting carbon to a maximum of 0.03%. This formulation is critical for preventing intergranular carbide precipitation during the welding process, thereby maintaining the corrosion resistance of the grain boundaries in the heat-affected zone without the need for post-weld heat treatment. It is also suitable for welding stainless steels stabilized with Titanium or Niobium, offering versatility in complex fabrication scenarios.

Industrial fabricators rely on Bonarc ER316L for its consistent chemical composition and excellent feedability. The rod produces a stable arc with minimal spatter, resulting in a clean, aesthetically pleasing weld bead that requires minimal post-weld cleaning. It is the preferred choice for MRO applications in chemical plants, paper mills, and pharmaceutical facilities where material integrity under corrosive stress is paramount.
