Elgaloy Hard 100 is a high recovery electrode, producing a weld metal deposit extremely rich in
chromium carbides which is highly resistant to abrasion but exhibits limited impact resistance. Ideal for
hardsurfacing components used in the mining and quarrying industries. Good wear and corrosion
resistance at elevated temperatures. Surface cracking is normal and can be reduced by preheating to
250-450°C. A buffer layer of Elgaloy Mix 18 is recommended for heavy build-ups or surfacing 13% Mn
steels to prevent crack propagation into base material. Deposits are not machinable but can be
ground. Also available as a self-shielded flux cored wire, Elgaloy Hard R 100 and as a flux coated
tubular electrode, Elgaloy Tube 100, designed to give high deposition rates at very low welding
Guide for usage:
The electrode is preferably to be used with DC+, to create a thick build up also AC is possible to use.
Excavator teeth, dredger bucket lips, sizing screens, rollers, screw conveyors, scraper and mixer
blades, crusher jaws and hammers, chutes, agricultureimplements, rolling mill guides sinter plant.
