S614029-084 - Hobart Tube-Alloy 952-S 3/32" Submerged Arc Hardfacing Wire

Industrial Grade Submerged Arc Hardfacing Wire

The Hobart Tube-Alloy 952-S is a premium-grade, metal-cored welding wire designed specifically for the submerged arc welding (SAW) process. Engineered as a modified high-carbon martensitic stainless steel, this alloy delivers exceptional performance in heavy industrial environments, particularly within the steel production sector. The 952-S formulation offers a significant upgrade over standard 420 stainless steel deposits, providing higher hardness levels while maintaining the critical toughness required to withstand heavy impact loads.

This wire is formulated to combat the rigorous conditions found in steel mills, where components are subjected to extreme heat, high pressure, and continuous metal-to-metal friction. The deposit structure is designed to resist thermal fatigue (fire cracking), a common failure mode in caster and mill rolls. By utilizing a metal-cored construction, the Tube-Alloy 952-S ensures high deposition rates and excellent arc characteristics, making it a highly efficient choice for extensive overlay operations on large cylindrical parts.

The 600 lb Auto-Pak packaging is optimized for high-volume automation, reducing downtime associated with spool changes and ensuring continuous, uninterrupted welding for large-scale reclamation projects. It is suitable for both single and multiple-layer buildups, providing flexibility in restoring worn dimensions on critical machinery. When used with a neutral flux, the wire produces a smooth, consistent bead profile with slag that is easily removed, minimizing post-weld cleanup and preparation time.

Primary applications for the Hobart Tube-Alloy 952-S include the surfacing of steel mill plate leveler rolls, straightener rolls, edger rolls, and descale rolls. Its unique metallurgical properties make it the preferred choice for maintenance and repair operations seeking to extend the service life of back-up rolls and other high-wear components. By balancing abrasion resistance with impact toughness, this wire helps facilities maintain operational efficiency and reduce the frequency of costly part replacements.
