Description

NIHONWELD NHF-43 is a premium chromium carbide hardfacing electrode specially alloyed with Niobium to create a hard and durable weld deposit that provides exceptional wear resistance to abrasion, impact, and corrosion
Ideal for a wide range of maintenance and repair applications in the construction, mining, agriculture, and manufacturing industries
Weld deposit is is non-machinable and can only be grinded
Produces a smooth and even weld bead
Excellent welder appeal due to smooth and steady arc with minimal spattering, and easy slag removal
Comes in special vacuum packed packaging for improved shelf life and top-level welding performance

Application

Construction: bucket teeth, grader blades, scraper blades, and cement press screws
Mining: shovel teeth, bucket teeth, ripper shanks, wear plates, and crusher jaws
Agriculture: plow shares, palmnut press screws, and cultivator blades
Manufacturing: dies, punches, and wear plates

Remarks

Preheat at 150�C and over in general

In case of multi-layer build-up welding and welding mother plates with hardening property, under-lay with low hydrogen type electrodes for mild steel

Dry the electrodes at 300-350�C for 30-60 minutes before use

Clean weld area properly before welding

Keep a medium long arc

Oscillation of the electrode with an amplitude up to 3-4 times the nominal diameter results in a very regular and smooth bead

The full properties of the alloy is obtainable in two layer deposits
