S540151-033 - Hardalloy 32 Hardfacing Build-Up Electrode 5/32"

Industrial Build-Up and Hardfacing Base

The Hobart Hardalloy 32 is a specialized heat-treatable alloy steel electrode engineered specifically for the build-up of carbon and low alloy steels. In the realm of industrial maintenance and repair operations (MRO), establishing a sound metallurgical foundation is critical before applying final hardfacing layers. Hardalloy 32 serves this purpose by providing a deposit with high compressive strength, making it an exceptional base for harder, more abrasion-resistant overlay alloys. This ensures that the final protective layer does not fail due to the deformation of the underlying material under heavy impact or load.

One of the primary technical advantages of Hardalloy 32 is its versatility in deposition. Unlike many hardfacing consumables that are limited to a specific number of layers to prevent cracking, this electrode is not limited to a maximum number of build-up layers. It exhibits excellent resistance to cracking even in multiple-pass deposits, allowing technicians to restore parts to their original dimensions with confidence. The electrode operates effectively on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility depending on the available power sources in the field or shop.

This consumable is particularly suited for the construction, mining, and heavy industrial sectors where equipment is subjected to severe mechanical stress. It is formulated to weld in Flat, Horizontal, and Vertical Up positions, facilitating repairs on large, immovable machinery. The 5/32-inch (4.0 mm) diameter allows for efficient deposition rates while maintaining control over the weld puddle. Packaged in a 10 lb hermetically sealed can, the electrodes are protected from moisture absorption, ensuring consistent arc performance and weld quality immediately upon opening.

Common industrial applications include the refurbishment of bucket teeth and lips, coupling boxes, crane wheels, and dragline buckets. It is also extensively used for repairing dredge ladder rolls, gear teeth, grizzly bars, kiln trunnions, mine car wheels, steel shafts, and tractor idlers. By using Hardalloy 32 to rebuild worn dimensions, facilities can significantly extend the service life of expensive capital equipment.
