Hobart Hardalloy 140: High-Performance Hardfacing Electrode

The Hobart Hardalloy 140 is a specialized hardfacing stick electrode designed to deposit a high chromium carbide alloy steel. Engineered for industrial environments where equipment faces severe wear, this electrode provides an overlay capable of withstanding high abrasion coupled with moderate impact. It is particularly effective in high-temperature applications, maintaining its wear resistance properties up to 1200 degrees Fahrenheit (649 degrees Celsius), making it a robust choice for equipment operating in extreme thermal conditions. Additionally, the deposit offers a degree of corrosion resistance, extending the service life of parts exposed to harsh elements.

This 1/8-inch (3.2 mm) diameter electrode is formulated for the Shielded Metal Arc Welding (SMAW) process and operates efficiently on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC). The recommended amperage range is 95 to 150 A. Users can expect a quiet, stable arc with excellent restrike characteristics, resulting in a smooth, ripple-free bead surface. The slag removal design simplifies post-weld cleaning, ensuring that maintenance operations are efficient. It is important to note that this electrode is designed for a maximum buildup of three layers to maintain the integrity of the deposit.

The Hardalloy 140 is a general-purpose hardfacing solution suitable for overlaying carbon steel, low alloy steel, or austenitic manganese base metals. It can also serve as a final overlay on top of buffer layers created by Hardalloy 32, Hardalloy 118, or ChromeMang. Its metallurgical composition ensures that critical components in construction, agriculture, and mining—such as crusher jaws, bucket teeth, and screw conveyors—remain operational for longer periods, reducing downtime and replacement costs.
