The Hobart Tube-Alloy 868-S is a high-performance metal-cored wire specifically engineered for the submerged arc welding (SAW) process. Designed to deposit a low alloy, martensitic steel, this wire is the industry standard for applications requiring resistance to metal-to-metal wear combined with good impact strength. With a diameter of 3\/32 inch, it provides excellent deposition rates and penetration profiles suitable for heavy industrial rebuilding.<\/p>\n
This alloy produces a deposit with a hardness range of 34-42 HRC, making it tough enough to withstand significant load-bearing pressure while remaining machinable with carbide tools. This characteristic is crucial for applications where the restored part must be machined back to original dimensional tolerances. The Tube-Alloy 868-S is designed to be used with neutral fluxes, ensuring that the deposit chemistry remains consistent and predictable regardless of arc voltage variations.<\/p>\n
Supplied in a substantial 600 lb Auto-Pak, this product is tailored for high-volume automation and continuous welding operations found in steel mills, mining maintenance shops, and heavy fabrication facilities. The bulk packaging minimizes downtime associated with spool changes, maximizing arc-on time and operational efficiency. Whether used for restoring crane wheels, mine car wheels, or tractor rollers, the Tube-Alloy 868-S delivers a sound, crack-resistant deposit that extends the service life of critical machinery components.<\/p>\n
