ED037119 - Lincoln UltraCore 308L P Flux-Cored Stainless Wire 1.6mm 33lb

Advanced Stainless Steel Joining Solution

The Lincoln Electric UltraCore® 308L P is a premier gas-shielded, flux-cored stainless steel wire designed for the rigorous demands of industrial fabrication. Engineered with a rutile slag system, this consumable (SKU: ED037119) meets AWS E308LT1-1 and E308LT1-4 classifications, ensuring compliance with critical code requirements for pressure vessels and structural components. The 1.6mm (1/16-inch) diameter allows for high-amperage operation and substantial deposition rates, making it an efficient choice for heavy-wall applications.

Metallurgically, the wire deposits an austenitic stainless steel weld metal with a nominal composition of 19% chromium and 9% nickel. The "L" designation indicates a low carbon content (maximum 0.04%), which is critical for preventing intergranular corrosion by minimizing carbide precipitation during the welding thermal cycle. This makes it specifically suitable for welding Type 304 and 304L stainless steels, as well as CF-8 and CF-3 castings. The flux formulation provides a fast-freezing slag, enabling operators to weld in all positions, including vertical-up and overhead, without compromising bead profile or integrity.

Operational efficiency is enhanced through the wire's compatibility with both 100% CO2 and 75% Argon / 25% CO2 shielding gas blends. While mixed gas offers a smoother arc and slightly higher tensile strength, the ability to use straight CO2 provides cost savings and deeper penetration. The vacuum-sealed packaging ensures low moisture levels upon opening, reducing the risk of hydrogen-induced cracking or porosity in the weld metal.
