S611943-084 - Hobart Tube-Alloy 877-S 1/8" Metal-Cored SAW Wire, 600lb Drum

Industrial Build-Up Alloy for Submerged Arc Welding

The Hobart Tube-Alloy 877-S is a premium metal-cored wire engineered specifically for the submerged arc welding (SAW) process. With a diameter of 1/8 inch (3.2mm), this wire is formulated to provide a sound, tough build-up alloy primarily used in the restoration and surfacing of steel mill components. It is particularly effective for continuous caster rolls and table rolls where components are subjected to extreme thermal cycling, heavy compressive loads, and metal-to-metal wear.

This alloy produces a deposit that balances hardness with ductility, ensuring that the overlay can withstand the thermal shock inherent in steel casting operations without cracking. The Tube-Alloy 877-S is designed for both single and multiple-layer applications, allowing for significant dimensional restoration of worn parts. Its metallurgical composition ensures a consistent response to heat treatment and provides a deposit that is fully machinable, facilitating the return of components to their original specifications.

Supplied in a 600lb Auto-Pak, this product is optimized for high-volume, automated welding environments. The bulk packaging minimizes downtime associated with spool changes, maximizing arc-on time and productivity in heavy fabrication and maintenance repair operations (MRO). When used with appropriate neutral fluxes, the wire exhibits excellent bead characteristics, easy slag removal, and low spatter, contributing to a high-quality surface finish essential for rolling mill applications.
