The Central Wire ER316L is a premium quality solid MIG welding wire designed for joining austenitic stainless steels of the 316 and 316L types. This consumable is manufactured to meet rigorous AWS A5.9 specifications, ensuring consistent chemistry and mechanical properties. The alloy composition includes approximately 18.5% chromium, 12.5% nickel, and 2.5% molybdenum. The addition of molybdenum significantly enhances the weld metal's resistance to pitting and crevice corrosion, particularly in chloride-containing environments.
A key feature of this wire is its "Low Carbon" (L) designation, with a maximum carbon content of 0.03%. This controlled chemistry is critical for preventing sensitization—the formation of chromium carbides at grain boundaries—which can lead to intergranular corrosion in the heat-affected zone. Consequently, this wire is suitable for applications where the weldment will be used in as-welded conditions without post-weld heat treatment.
The 0.045-inch (1.2mm) diameter is optimized for medium-to-heavy gauge fabrication, allowing for higher deposition rates and deeper penetration compared to thinner wires. The wire is precision layer wound on a 10lb spool, ensuring tangle-free feeding and stable electrical contact at the contact tip. It is designed for use with Direct Current Electrode Positive (DCEP) polarity and performs best with shielding gas mixtures such as 98% Argon/2% Oxygen or Helium-rich Tri-mixes.
