57552 - Bohler E316LT1-1/4 Stainless Flux Core Wire .035 12.5kg

High-Deposition E316LT1 Flux Core Wire

Elevate your stainless steel welding operations with the Bohler Flux Core 316LT1 .035" 12.5kg Spool. This gas-shielded flux-cored arc welding (FCAW) wire is the professional's choice for joining molybdenum-bearing austenitic stainless steels like AISI 316 and 316L. Engineered to deliver superior mechanical properties and corrosion resistance, this wire meets AWS A5.22 E316LT1-1 and E316LT1-4 specifications, ensuring code-compliant welds for critical infrastructure and pressure vessel applications.

The 316LT1 formula features a fast-freezing rutile slag system that provides excellent weld puddle control. This makes it an outstanding choice for out-of-position welding, allowing operators to deposit high-quality welds in the vertical and overhead positions with ease. Unlike solid MIG wires that may require complex pulsed power sources for positional work, this flux-cored wire relies on its slag support to hold the molten pool, significantly increasing deposition rates and productivity. The resulting weld deposit exhibits high tensile strength and ductility, matching the base material's performance characteristics.

Operational efficiency is a core advantage of this Bohler product. The 0.035" (0.9mm) diameter is versatile enough for a wide range of material thicknesses, while the 12.5kg (27.5lb) spool size optimizes the balance between portability and run-time. The wire is designed to operate with DCEP polarity and performs exceptionally well under both 100% CO2 and 75% Argon / 25% CO2 shielding gases. Using mixed gas typically yields a smoother arc and less spatter, while CO2 offers deeper penetration and cost savings.

Industrial Applications and Performance

This wire is indispensable in sectors requiring high resistance to intergranular corrosion, such as the textile, paper, and pharmaceutical industries. The extra-low carbon content ensures the integrity of the weld zone against sensitization. Furthermore, the flux core protects the weld pool from atmospheric contamination more robustly than solid wire gas shielding alone, making it slightly more forgiving in drafty shop conditions. With easy slag removal and a bright bead finish, post-weld grinding and polishing times are drastically reduced, lowering overall project costs.
