S482931-036 - Hobart Sterling AP 316/316L Stainless Stick Electrode, 3/32", 5lb Can

High-Performance Stainless Steel Electrode for Critical Applications

The Hobart Sterling AP 316/316L is a premium quality stick electrode designed for the Shielded Metal Arc Welding (SMAW) of austenitic stainless steels. Formulated with a rutile-based coating, this electrode is engineered to meet AWS E316L-16 classifications, providing exceptional mechanical properties and corrosion resistance. The "AP" designation signifies its "All Position" capability, ensuring consistent performance in flat, horizontal, vertical, and overhead positions, making it a versatile solution for complex fabrication and maintenance tasks.

Metallurgically, the electrode deposits weld metal with a chemical composition matching Type 316 stainless steel but with an extra-low carbon content (0.04% maximum). This reduction in carbon is critical for preventing sensitization—the precipitation of chromium carbides at grain boundaries—which can lead to intergranular corrosion in the heat-affected zone. Additionally, the inclusion of molybdenum enhances the weld's resistance to pitting and crevice corrosion, particularly in chloride-rich environments. This makes the Sterling AP 316/316L ideal for welding base metals of similar composition, such as AISI 316, 316L, and stabilized 318 grades.

The electrode operates with a smooth, soft arc that minimizes spatter and produces a flat to slightly convex bead profile with excellent wetting action. The slag system is designed for easy detachability, often lifting by itself upon cooling, which reduces post-weld cleaning labor. It is compatible with both Alternating Current (AC) and Direct Current Electrode Positive (DCEP), providing flexibility for various power source configurations. Packaged in a hermetically sealed 5lb can, the electrodes are protected from moisture absorption, ensuring fresh performance right out of the container.

Primary applications include the fabrication and repair of equipment in the food and beverage, pharmaceutical, textile, and chemical processing industries. It is also widely used in the pulp and paper sector and for architectural structures requiring high aesthetic standards and durability against environmental elements.
