Summary
Duroxite overlay products from Hardox Wearparts can add weeks, months, even years of trouble-free operations to your most extreme wear situations.
 
 
Duroxite - General
 
 
 
Duroxite™ - Overview

The ultimate Duroxite product for your application depends on the material - whether rock, sand, gravel or other substance—striking or sliding along the surface of your wear part. It also depends on the angle and speed of impact, and the operating temperature. Below is an overview of the Duroxite product line.
 
  PRODUCT   DESCRIPTION   APPLICATIONS   OVERLAY PROPERTIES
  SLIDING WEAR
   
  DUROXITE 100

  Multi-purpose overlay product with high quality and premium performance.

Specially designed for severe abrasive environments.

Appropriate to take moderate to low impact applications.

Fabricated by depositing chromium-rich, abrasion-resistant materials on mild steel backing.

The multiple-layer overlay is capable of maintaining full wear resistance up to 350ºC (660ºF).
 
  Chutes/hoppers, liners for truck beds, dozer blades, shovel buckets, dragline buckets and excavators, separator guide vanes, discharge cones for clinker storage bins, chutes for sintering ore conveying, outlet ducts for clinker grinding mills, receiving hoppers, dredging pipes and pumps, suction pipelines, pump discharges, fan blade/ housings, coke vibrating screen plates, coal handling chutes, coal feeder liners, crusher screen plates, classifier cones, journal liners, silo bunkers.   Bulk hardness:
Single pass 55 to 57 HRC
Double pass 56 to 59 HRC
Triple plus passes 58 to 63 HRC
Carbide hardness:
1700 HK
Volume fraction of primary carbides:

  EXTREME WEAR
   
  DUROXITE 210


 
  Primarily designed for severe abrasive wear and impact up to 600°C (1100°F).

Provides up to 4 times longer service life than Duroxite 100 due to its high proportion of extremely hard multiple-alloy carbides.

Comprised of specially formulated abrasive-resistant materials deposited on mild steel backing plate.
  Cement furnace components, sinter plant parts, fan blades, mixer blades, crews, gyratory mantles, coal and cement pulverizer rolls and grinding, ore sintering, crushing, riddling, blast furnace hoppers, throats and ovens.   Bulk hardness:
60 to 65 HRC
Carbide hardness: 2500-3000 HK
Volume fraction of primary carbides:
30-50%
ASTM G65-Procedure A weight loss: 0.12 g max.
   
   
  DUROXITE 211
HARDOX BASE PLATE


 
   For severe wear and impact applications.

Contains primary chromium carbides and refined multiple-alloy complex carbides deposited on strong Hardox® base plate.

Provides higher impact resistance than Duroxite 210 at both room and elevated temperatures up to 350°C (660°F), but impact performance is best at room temperature.
  Screen plates, loader bucket liners, feeding systems for ball mills, coal discharger chutes, loader bucket liners, bucket lip shrouds, bucket side shrouds, conveyor liners.   Bulk hardness:
