Weld Star Dual Core 309L-T1 Wire [15kg Spool]

The Weld Star Dual Core 309L-T1 is a premium rutile flux cored wire (FCAW) designed for the all positional welding of dissimilar metals. With its enriched 24% Chromium and 13% Nickel chemistry, it provides a safe, crack resistant solution for joining austenitic stainless steels (304L, 316L, 321) to non alloyed or low alloyed steels.

The "T1" designation indicates a fast freezing slag system that supports the molten pool, allowing for maximum productivity in vertical up (PF) and overhead (PE) positions. It offers a stable, soft arc with automatic slag release, resulting in a bright, clean bead appearance. Whether you are installing stainless handrails on carbon steel structures or applying a buffer layer before hard facing, the Dual Core 309L-T1 ensures X-ray quality results and superior penetration.

Key Features

All Position Professional: Optimised for out of position work, including vertical and overhead structural joints.

Dissimilar Metal Specialist: Specifically engineered to prevent cracking when joining stainless steel to carbon steel.

Low Carbon (L) Deposit: Minimises carbide precipitation to ensure the corrosion resistance of the transition zone.

Automatic Slag Release: Advanced rutile flux makes post weld cleaning fast and efficient.

High Purity Chemistry: Excellent mechanical properties with a typical elongation of 35% and impact strength down to -60°C.

Precision Feed: Layer wound on a 15kg BS300 basket spool to ensure consistent wire delivery during high duty cycles.
