57544 - Böhler FOXcore 308L-T1 .045" Gas Shielded Flux Core Stainless Wire (33lb Spool)

Premium Stainless Steel Flux Core Wire for Demanding Applications

The Böhler FOXcore 308L-T1 is a high-performance rutile flux-cored wire engineered for the precision welding of 1.4307 / 304L type stainless steels. Designed with the professional welder in mind, this .045-inch diameter wire comes in a substantial 33 lb (15 kg) spool, ensuring long run times and reduced downtime for spool changes in industrial environments. It carries the AWS classification E308LT1-1-4, signifying its robust capability in gas-shielded flux core arc welding (FCAW-G) processes.

One of the standout features of the FOXcore 308L-T1 is its exceptional positional capability. Thanks to a fast-freezing rutile slag system, this wire excels in vertical-up and overhead positions, where controlling the weld pool can traditionally be challenging with stainless fillers. The slag detaches very easily, often peeling off by itself, revealing a bright, clean bead with minimal oxidation. This reduces post-weld cleaning time significantly, improving overall productivity in fabrication shops.

Metallurgically, this wire is formulated to resist corrosion under moderately severe conditions, such as exposure to oxidizing acids and cold or dilute reducing acids. It is also compatible with titanium or niobium-stabilized steels like 321 and 347, provided the service temperature does not exceed 750°F. For applications requiring extreme temperature resilience, the FOXcore 308L-T1 remains tough down to cryogenic temperatures of -320°F, making it a versatile choice for piping, tanks, and structural stainless projects.

The wire produces a wide, stable arc that ensures even penetration into the root and side walls, effectively preventing lack of fusion defects. Whether you are fabricating chemical vessels or performing maintenance on stainless infrastructure, the Böhler FOXcore 308L-T1 delivers consistent, high-quality results with the reliability expected from the Böhler Welding brand.
