S481944-032 - Hobart Sterling AP E308/308L-16 Stainless Stick Electrode - 1/8 in

Technical Overview: Hobart Sterling AP 308/308L

The Hobart Sterling AP 308/308L is a premium quality Shielded Metal Arc Welding (SMAW) electrode designed for the joining of austenitic stainless steels. Formulated with a rutile-based coating, this electrode meets AWS E308-16 and E308L-16 classifications, offering the dual benefit of high strength and corrosion resistance. The 'L' designation indicates a low carbon content (maximum 0.04%), which is critical for minimizing carbide precipitation during the welding process and in service temperatures, thereby reducing the risk of intergranular corrosion in the heat-affected zone (HAZ).

Engineered for versatility, the Sterling AP (All Position) provides exceptional arc stability and puddle control in flat, horizontal, vertical, and overhead positions. It is specifically optimized for welding 18% Chromium / 8% Nickel steels, including Types 301, 302, 304, 305, and 308. The electrode operates effectively on both Alternating Current (AC) and Direct Current Electrode Positive (DCEP), providing a smooth spray-type transfer with minimal spatter. The resulting weld bead is uniform, flat to slightly convex, and features finely rippled aesthetics with excellent tie-in.

Metallurgically, the deposited weld metal exhibits high ductility and toughness. The slag system is designed for easy removal, often self-peeling, which reduces post-weld cleanup time. This electrode is an ideal choice for applications requiring radiographic quality welds and consistent mechanical properties in diverse industrial environments.
