S616529-084 - Hobart Tube-Alloy 861-S 3/32" Sub-Arc Hardfacing Wire Drum

Industrial Hardfacing with Hobart Tube-Alloy 861-S

The Hobart Tube-Alloy 861-S is a premium metal-cored welding wire engineered specifically for the submerged arc welding (SAW) process. Designed to meet the rigorous demands of heavy industry, this wire deposits a martensitic steel alloy that provides an exceptional balance of hardness and toughness. It is particularly effective in applications involving severe metal-to-metal wear combined with moderate impact and abrasion. The 3/32-inch diameter ensures deep penetration and substantial buildup capabilities, making it a staple for maintenance and repair operations in steel mills, mining facilities, and heavy manufacturing plants.

One of the defining characteristics of the Tube-Alloy 861-S is its ability to produce a deposit that maintains its integrity under high compressive loads. This makes it the ideal choice for resurfacing cylindrical components such as continuous caster rolls, table rolls, crane wheels, and idlers. The metal-cored construction enhances current density, resulting in higher deposition rates compared to solid wires, which translates to increased productivity during extensive buildup operations. When used with a neutral flux, the wire yields a consistent chemical composition, ensuring that the desired mechanical properties—typically in the range of 48-52 HRC—are achieved layer after layer.

This product is supplied in a 600lb Auto-Pak, a bulk packaging solution designed to support continuous, automated welding environments. The large volume reduces the frequency of spool changes, thereby minimizing arc-off time and maximizing throughput. The wire is precision-wound to ensure tangle-free feeding, which is critical for maintaining arc stability and bead uniformity in automated submerged arc setups. Whether restoring worn components to their original dimensions or applying a protective overlay to new parts, the Hobart Tube-Alloy 861-S offers a reliable, high-performance solution for extending equipment service life.
