S481931-036 - Hobart Sterling AP 308L-17 Stainless Stick Electrode 3/32" (5lb Can)

High-Performance Stainless Steel Fabrication

The Hobart Sterling AP 308/308L is a premium quality stick electrode designed for the welding of austenitic stainless steels. Engineered with a rutile-based coating (AWS E308L-17), this electrode provides exceptional arc stability and weld bead aesthetics. It is specifically formulated to join Type 304, 304L, 308, and 308L base metals, making it an essential consumable for industries requiring high corrosion resistance and structural integrity.

One of the critical technical advantages of the Sterling AP 308L is its controlled chemical composition. The "L" designation indicates a maximum carbon content of 0.04%, which is crucial for minimizing carbide precipitation during the thermal cycle of welding. This feature significantly reduces the risk of intergranular corrosion in service, ensuring the longevity of the weldment in harsh environments. The electrode deposits weld metal with a nominal composition of 19.5% Chromium and 10% Nickel, providing mechanical properties that meet or exceed AWS A5.4 standards.

The "AP" in Sterling AP stands for All Position, highlighting its versatility in complex fabrication scenarios. Whether welding in flat, horizontal, vertical, or overhead positions, the electrode maintains a smooth, soft arc with low spatter levels. The resulting weld bead is finely rippled, flat to slightly convex, and requires minimal post-weld grinding. This electrode operates effectively on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), offering flexibility for various power source configurations found in maintenance and production environments.

Technical Specifications

Designed for critical applications in petrochemical, food and beverage, and pulp and paper industries, the Hobart Sterling AP delivers consistent X-ray quality welds. The slag system is designed for easy detachment, often curling off the bead as it cools, which improves productivity by reducing inter-pass cleaning time. With a tensile strength typically ranging around 87,000 PSI and elongation of approximately 42%, it provides a robust and ductile joint suitable for pressure vessels and piping systems.
