S613943-084 - Hobart Tube-Alloy 954-S 1/8" Hardfacing SAW Wire Drum

Technical Overview of Hobart Tube-Alloy 954-S

The Hobart Tube-Alloy 954-S is a premium-grade, metal-cored submerged arc welding (SAW) wire engineered specifically for hardfacing and build-up applications requiring high resistance to metal-to-metal wear. This 1/8-inch diameter wire is formulated to deposit a martensitic steel alloy that balances hardness with compressive strength, making it an ideal solution for restoring dimensions to worn industrial components. The wire is supplied in a substantial 600 lb Auto-Pak, designed to facilitate continuous, automated welding processes found in heavy fabrication and remanufacturing facilities, such as steel mills and heavy equipment repair shops.

Technically, the Tube-Alloy 954-S deposit exhibits a hardness range typically between 48 and 52 HRC, depending on the specific welding parameters, cooling rate, and the number of layers applied. The microstructure is predominantly martensitic, which provides the necessary toughness to withstand moderate impact while maintaining a hard surface that resists sliding abrasion and deformation under load. It is recommended for use with neutral fluxes to maintain the intended alloy chemistry and mechanical properties of the weld deposit. The wire is suitable for multiple layer buildup, although specific preheat and interpass temperature controls should be observed to prevent cracking in the hard deposit, especially on high-carbon substrates.

This consumable is particularly effective for applications involving rolling or sliding friction. The deposit is not machinable by conventional methods and must be finished by grinding, which is characteristic of high-hardness martensitic overlays. The 600 lb bulk packaging minimizes changeover downtime, optimizing the duty cycle of submerged arc welding stations. By utilizing Tube-Alloy 954-S, maintenance engineers can significantly extend the service life of critical components subject to severe operational stresses, ensuring reliability and reducing the total cost of ownership for heavy machinery.
