S605939-065 - Hobart Tube-Alloy 258 TiC-O Hardfacing Wire 7/64" 250lb Drum

Premium Titanium Carbide Hardfacing for Severe Environments

The Hobart Tube-Alloy 258 TiC-O is a highly specialized self-shielded, flux-cored wire designed to tackle the most demanding industrial wear problems. Engineered with a unique chemistry, this wire deposits a martensitic steel alloy that is densely populated with finely dispersed titanium carbides. This microstructure provides a significant advantage over traditional chromium carbide overlays, particularly in applications involving a combination of severe abrasion and heavy impact. The titanium carbides are extremely hard, offering a primary line of defense against grinding wear, while the martensitic matrix provides the necessary toughness to withstand impact without spalling.

This 7/64-inch diameter wire is supplied in a substantial 250lb Auto-Pak, making it an ideal choice for high-volume, automated, or semi-automated hardfacing operations where downtime for spool changes must be minimized. As an open-arc (self-shielded) product, it requires no external shielding gas, simplifying the setup for field repairs and large-scale fabrication. The deposit typically achieves a hardness of 58-62 HRC, ensuring long-lasting protection for heavy earthmoving and processing equipment.

Industrial maintenance professionals rely on Tube-Alloy 258 TiC-O for extending the service life of critical components in mining, quarrying, and construction. It is specifically formulated to bond well with carbon, low alloy, and manganese steel substrates. While the deposit is non-machinable and must be finished by grinding, its superior wear life significantly reduces the frequency of maintenance intervals, ultimately lowering the total cost of ownership for capital equipment.
