57548 - Avesta 309LT-1 Flux Core Stainless Wire .045 15kg

Industrial Grade Avesta 309LT-1 Flux Core Wire

The Avesta 309LT-1 is a premium flux-cored arc welding (FCAW) wire designed for high-performance industrial applications. Engineered with a nominal composition of 24% Chromium and 13% Nickel, this wire is the industry standard for joining stainless steels to carbon or low-alloy steels. It is also exceptionally effective for depositing buffer layers on carbon steel prior to overlaying with 308 or 316 grades. The .045-inch diameter ensures deep penetration and robust deposition rates suitable for heavy fabrication environments.

This wire is formulated for all-position welding, making it versatile for complex structural assemblies where out-of-position welding is required. The flux formulation supports a stable arc and produces a fast-freezing slag that supports the weld puddle in vertical and overhead positions. It operates effectively with both 100% CO2 and Argon/CO2 mixed shielding gases, providing flexibility based on shop availability and desired arc characteristics. The 15kg spool size is optimized for industrial wire feeders, reducing downtime associated with frequent spool changes.

Avesta's manufacturing process ensures consistent wire feeding and chemical composition, critical for meeting rigorous AWS E309LT1-1 and E309LT1-4 specifications. The low carbon content (indicated by the 'L') minimizes carbide precipitation, thereby reducing the risk of intergranular corrosion in the weld zone. This makes the Avesta 309LT-1 an essential consumable for maintenance, repair, and overhaul (MRO) operations involving diverse metal grades and structural transitions.
