61780805V - Bonarc ER316L Stainless Steel MIG Wire .030 5kg Spool

Premium Grade ER316L Stainless Steel MIG Wire

The Bonarc ER316L .030" (0.8mm) MIG Wire is a high-quality austenitic stainless steel consumable designed for critical fabrication tasks requiring superior corrosion resistance. Formulated with a nominal composition of 18% Chromium, 12% Nickel, and 2-3% Molybdenum, this wire meets AWS A5.9 specifications. The addition of Molybdenum significantly enhances the alloy's resistance to pitting and crevice corrosion, particularly in chloride-rich environments such as marine applications or chemical processing plants.

This "L" grade (Low Carbon) variant ensures a maximum carbon content of 0.03%, which is crucial for preventing carbide precipitation during the welding process. This feature minimizes the risk of intergranular corrosion in the heat-affected zone (HAZ), eliminating the need for post-weld annealing in many applications. The wire is precision-wound on a 5kg spool, ensuring consistent feedability and stable arc characteristics when used with standard MIG welding equipment.

Ideally suited for joining AISI 316 and 316L base metals, the Bonarc ER316L also performs exceptionally well on 304/304L grades where increased corrosion protection is desired. It is compatible with Argon/Oxygen or Argon/CO2 shielding gas mixtures, providing excellent wetting action and a clean, high-quality bead profile.
