Weld Star Dual Core 316L-T1 Wire [15kg Spool]

The Weld Star Dual Core 316L-T1 is a premium rutile flux cored wire (FCAW) designed for the all positional welding of Molybdenum-bearing austenitic stainless steels like 316 and 316L. With its 3% Molybdenum content, it provides the critical pitting resistance required for components exposed to chlorides, marine salt, and various industrial acids.

The "T1" designation indicates an advanced fast freezing slag system that supports the molten pool, allowing for maximum productivity in vertical-up (PF) and overhead (PE) positions. This wire combines the corrosion resistance of a specialty alloy with the high deposition rates of a cored wire, producing X-ray quality welds with an attractive bead appearance and automatic slag release. Precision layer wound on a 15kg BS300 basket spool, it is the professional choice for critical stainless steel infrastructure in the chemical, pharmaceutical, and offshore sectors.

Key Features

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

Marine & Acid Resistant: 2.9% Molybdenum alloy provides superior protection against pitting and crevice corrosion.

Low Carbon (L) Deposit: Safeguards against intergranular corrosion by minimising carbide precipitation at the grain boundaries.

Automatic Slag Release: Slag self detaches to reveal a clean, smooth finish, significantly reducing post weld cleaning time.

Excellent Penetration: Offers deep, consistent penetration with a stable, low spatter arc.

Cryogenic Reliability: Maintains high impact strength (50 J) at sub-zero temperatures down to -60°C.
