Duroxite 100

Duroxite® 100 is manufactured by depositing chromium-rich, abrasion-resistant materials on a mild steel base plate using a traditional arc welding process. The hard-facing overlay plate is suitable for severe abrasive wear and moderate to low impact applications. The multiple-layer overlay is also capable of maintaining full wear resistance up to 350 °C (660°F) and the typical surface hardness of 55 HRC at elevated temperatures up to 540°C (1000°F). Duroxite® 100 is available in single layers or multiple layers up to 20 mm (3/4”) in overlay thickness

Key benefits

Same wear resistance guaranteed from surface down to 75% of the overlay
Optimal carbide composition to provide good combination of wear resistance and homogenous bonding
Good formability due to staggered cracking pattern on overlay surface

Typical Applications

Duroxite® 100 is widely used in the mining, power generation, cement, dredging, steel production, waste handling, glass production, and pulp and paper industries. Some specific applications include:

Mining: Chutes/hoppers, liners for truck beds, dozer blades, shovel buckets, dragline buckets, excavators
Cement: Separator guide vanes, discharge cones for clinker storage bins, chutes for sintering ore conveying, outlet ducts for clinker grinding mills, receiving hoppers
Dredging: Dredging pipes and pumps, suction pipelines, pump discharges
Steel: Fan blade/housings, coke vibrating screen plates
Power: Coal handling chutes, coal feeder liners, crusher screen plates, classifier cones, journal liners, silo bunkers

Mechanical Properties

Surface Hardness

Number of overlay passes	Typical surface hardness ¹⁾ (mm)
Single pass	55 to 57 HRC (590 to 630 HV)
Double passes	59 to 62 HRC (675 to 750 HV)
Triple and more passes	60 to 64 HRC (700 to 810 HV)

¹⁾Surface hardness is measured on machined flat surface just below overlay surface.

Wear Propertie

Number of overlay passes	ASTM G65 - Procefure A weight loss ²⁾
	Surface	75% depth of overlay ³⁾
Single pass	0.25 g maximum	0.25 g maximum
Multiple passes	0.18 g maximum	0.18 g maximum

²⁾ASTM G65 is a standard test measuring sliding abrasion resistance using a dry sand/rubber wheel apparatus. ASTM G65-Procedure A is the most severe test method.

³⁾ASTM G65 wear test is conducted at 75% depth of the overlay materials to ensure consistently good wear resistance from the top surface through to the depth of 75% of the overlay

Tolerances

Thickness

Overall and overlay thickness tolerances can be guaranteed within +10% of specified thickness.

Flatness

Plate flatness tolerance can be guaranteed within ±3 mm (±1/8”) over 1.5 m (5’) plate length for plate dimensions equal to or less than 1.5 m (5’) x 3.0 m (10’). For plates greater than 1.5 m (5’) wide by 3.0 m (10’) long, the following flatness guarantees apply.
