S611929-084 - Hobart Tube-Alloy 877-S Submerged Arc Hardfacing Wire 3/32 600lb Drum

Maximize Uptime with High-Performance Hardfacing

Welders and fabricators tasked with the critical job of rebuilding steel mill rolls know that material consistency is key. The Hobart Tube-Alloy 877-S 3/32" wire is built to deliver that consistency, layer after layer. This submerged arc wire is a go-to choice for surfacing continuous caster rolls, offering a smooth, stable arc and high deposition rates that help you get the job done efficiently. The metal-cored design ensures excellent current transfer and deep penetration, resulting in a strong bond with the base metal.

The deposit you get with Tube-Alloy 877-S is a tough, modified stainless steel that stands up to the punishment of the mill. It is specifically formulated to resist "fire cracking"—the thermal fatigue caused by rapid heating and cooling cycles. This means the rolls you rebuild will last longer in service, reducing the frequency of tear-downs and repairs. Whether you are applying a buffer layer or the final overlay, this wire handles well and produces a bead that is easy to machine back to tolerance.

Packaged in a 600lb Auto-Pak, this wire is designed for serious production. The large drum format means you spend less time swapping out spools and more time welding. The wire pays out smoothly from the drum, preventing feed issues that can cause defects in the overlay. This is especially important in automated submerged arc setups where interruptions can compromise the integrity of the roll surface.

If you are looking for a wire that balances toughness, wear resistance, and weldability, Hobart Tube-Alloy 877-S is the professional's choice. It takes the guesswork out of roll reclamation, giving you a high-quality deposit that extends the life of table rolls and idlers, keeping the mill running smoothly and efficiently.
