OVERVIEW

Industrial Grade Abrasion Resistance

The Hobart Hardalloy 148 is a premium 3/16-inch hardfacing stick electrode designed specifically for applications subjected to severe abrasion and low-to-moderate impact. Engineered with a high chromium carbide chemistry, this electrode deposits a weld metal consisting of primary chromium carbides in an austenitic matrix. This metallurgical structure delivers a typical hardness of Rc 55-60, making it an excellent choice for extending the service life of industrial components in mining, agriculture, and construction environments.

Packaged in a durable 10 lb can, the Hardalloy 148 is formulated to operate efficiently on both AC and DC+ (Reverse Polarity) currents. The electrode provides a smooth arc with moderate penetration, minimizing dilution with the base metal to maintain high hardness values even in the first pass. It is important to note that the deposit is non-machinable and can only be finished by grinding. The weld metal will naturally develop cross-checking (stress relief cracks), which is a normal and desirable characteristic for high-alloy hardfacing deposits to prevent spalling.

FAQ

The Hobart Hardalloy 148 typically produces a hardness of Rockwell C 55-60, depending on base metal dilution and the number of layers applied.

No, the deposit is extremely hard and non-machinable. It can only be finished by grinding.

This electrode can be run on both AC (Alternating Current) and DCEP (Direct Current Electrode Positive).

Yes, this electrode is designed to 'cross-check' or form relief cracks. This relieves residual stress in the hard deposit and helps prevent the coating from spalling or peeling off.

It is generally recommended to limit buildup to 2 or 3 layers. Excessive layers of high chromium carbide can lead to spalling due to high internal stresses.

For the 3/16" diameter rod, a range of approximately 150 to 220 Amps is typically recommended.

It offers moderate impact resistance but is primarily designed for severe abrasion. For high impact applications (like rock crushing impactors), a manganese steel electrode might be more appropriate.

Preheat depends on the base metal's carbon content and thickness. High carbon or alloy steels usually require preheat to prevent underbead cracking, though the hardfacing layer itself will check.
