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

Industrial-Grade Roll Reclamation Alloy

The Hobart Tube-Alloy 877-S is a premium metal-cored welding wire engineered specifically for the rigorous demands of the steel industry. Designed for use with the submerged arc welding (SAW) process, this 3/32-inch diameter wire deposits a modified 400 series stainless steel alloy that excels in rebuilding and surfacing continuous caster rolls. The 877-S formulation is chemically balanced to produce a sound, tough deposit that withstands the extreme thermal cycling and mechanical stress inherent in steel production.

One of the primary challenges in maintaining steel mill rolls is combating thermal fatigue, often manifested as fire cracking. Tube-Alloy 877-S addresses this by providing a deposit with superior resistance to thermal shock. Additionally, the alloy offers excellent metal-to-metal wear resistance, maintaining the dimensional integrity of table rolls and caster rolls over extended campaigns. This wire is suitable for both single and multiple-layer build-up, allowing for substantial restoration of worn components.

Supplied in a substantial 600lb Auto-Pak, this product is tailored for high-volume, automated welding cells where downtime for spool changes must be minimized. The bulk packaging ensures a straight, tangle-free feed, which is critical for maintaining consistent arc stability and bead geometry during long overlay procedures. When paired with a suitable neutral flux, Tube-Alloy 877-S delivers a clean, slag-releasing bead profile that reduces post-weld cleaning time and machining allowances.

For maintenance, repair, and operations (MRO) professionals in the steel sector, the Hobart Tube-Alloy 877-S represents a reliable solution for extending the lifecycle of capital-intensive equipment. Its metallurgical properties are optimized to prevent premature failure of rolls caused by the harsh combination of heat, pressure, and friction found in continuous casting lines.
