S613729-084 - Hobart Tube-Alloy 810-S 3/32" Submerged Arc Hardfacing Wire, 600lb Drum

Technical Overview of Hobart Tube-Alloy 810-S

The Hobart Tube-Alloy 810-S is a premium metal-cored welding wire designed specifically for the submerged arc welding (SAW) process. Engineered for heavy industrial hardfacing applications, this wire deposits a modified 420 martensitic stainless steel alloy. It is formulated to provide exceptional resistance to metal-to-metal wear, corrosion, and thermal fatigue, making it the industry standard for surfacing continuous caster rolls and similar steel mill components.

With a diameter of 3/32 inch, this wire offers high deposition rates and deep penetration when paired with an appropriate neutral flux. The metal-cored construction ensures consistent chemistry and superior feedability, particularly in automated setups utilizing the 600 lb Auto-Pak bulk packaging. The deposited weld metal exhibits a microstructure that balances hardness with toughness, allowing it to withstand the rigorous thermal cycling found in steel production environments without premature cracking or failure.

Fabricators and maintenance engineers choose Tube-Alloy 810-S for its reliability in restoring critical dimensions to worn parts. The deposit is machinable with carbide tooling, allowing for precise finishing after welding. It is essential to use a neutral flux to maintain the intended alloy balance, as active fluxes may alter the chemical composition and degrade the mechanical properties of the overlay. This product is supplied in a substantial 600 lb drum, minimizing downtime for spool changes in high-volume operations.

Industrial Specifications

This wire is categorized under specialty hardfacing consumables. It is distinct from standard joining wires due to its high alloy content tailored for surface protection rather than structural integrity. The 810-S formulation is specifically optimized for the unique wear mechanisms present in steel casting and processing lines, offering a significant extension in service life for expensive capital equipment.
