D707 Tungsten-Carbide Hardfacing
Tungsten-carbide reinforced deposit for extreme abrasion.
Material overview
The Hardfacing & Wear Welding Consumables catalog describes D707 Tungsten-Carbide Hardfacing as follows: Tungsten-carbide reinforced deposit for extreme abrasion. Reviewers should evaluate WC particles HV 2000+ in tough matrix, extreme abrasion, and limited impact. The grade record lists Dredger cutter teeth, augers, mining and oilfield tools, and extreme wear among typical applications. The dataset currently includes 7 property records covering chemical composition and mechanical properties. Standards and form records reference A5.21 and A5.13 and Covered Electrode and Flux-Cored Wire. Final supply conditions remain subject to specification, inspection, and export-control review.
