S541051-033 - Hobart Hardalloy 148 Hardfacing Electrode 5/32 Inch 10lb Can

High-Performance Hardfacing for Elevated Temperatures

The Hobart Hardalloy 148 is a premium hardfacing stick electrode designed to deposit a high carbon-chromium austenitic plus carbide alloy steel. This unique metallurgical composition is engineered specifically to overlay surfaces that must withstand light abrasion accompanied by impact, making it a critical consumable for heavy industrial maintenance and repair operations. One of the standout characteristics of the Hardalloy 148 is its ability to retain hardness at elevated temperatures, performing reliably up to 1200 degrees Fahrenheit (650 degrees Celsius). This thermal stability ensures that protective overlays remain effective even in high-heat friction environments where standard hardfacing alloys might soften or fail.

Technically, the electrode offers a quiet and stable arc with very fast transfer, resulting in a deposit that displays a shiny surface similar to stainless steel. The formulation provides minimum penetration, which is advantageous when dilution with the base metal needs to be minimized to maintain the alloy's wear-resistant properties. It exhibits magnificent edge-building capability and good wetting characteristics, allowing operators to achieve precise bead placement and sound deposits. The slag system is designed to be easily removable, reducing post-weld cleanup time and improving overall productivity during multi-pass applications (up to a maximum of three layers).

This electrode is particularly effective for combating metal-to-metal frictional wear. It is suitable for use in the construction and mining industries where equipment components face constant grinding and impact forces. The 5/32-inch (4.0 mm) diameter rod operates optimally around 160 Amps and can be used with both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility depending on the available power source. Packaged in a 10 lb (4.5 kg) hermetically sealed can, the electrodes are protected from moisture absorption, ensuring consistent performance right out of the container.
