Product Description Overlay properties Applications
DuroxiteTM 100 DuroxiteTM 100 is fabricated by depositing chromium-rich abrasion- resistant materials on mild steel backing. The hardfacing overlay is suitable for severe abrasive wear and moderate to low impact applications. It offers in both plate and pipe. Bulk hardness:

Single pass 55 to 57 HRC

Double passes 56 to 59 HRC Triple and more passes 58 to 63 Carbide hardness: 1700 HK

Volume fraction of carbides: 30-50% ASTM G65-Procedure A weight loss: 0.19g max.

Liners for truck bed, dozer blade, bucket and excavator, chute /hopper, discharge cone, dredging pipe, dredging pump,  blast furnace liner, fan blade, coke vibrating screen plate, coal handling chute, coal feeder liner, crusher screen plate, classifier cone, journal liner, silo bunkers.
DuroxiteTM 101 DuroxiteTM 101 is to weld chormium- riched carbide overlay on quench & tempered (Q&T) steel backing plate. The overlay has same wear properties as DuroxiteTM 100, but with a better impact resistance and greater safety margin compared to mild steel backing due to employing stronger Q&T base metal. Bulk hardness:

Single pass 55 to 57 HRC

Double passes 56 to 59 HRC

Triple passes 58 to 63 Carbide hardness: 1700 HK

Volume fraction of carbides: 30-50% ASTM G65-Procedure A weight loss: 0.19g max.

Coal discharger chute, loader bucket liner, bucket lip shroud, bucket side shroud
DuroxiteTM 200 DuroxiteTM 200 is composed of primary chromium-rich carbides with extremely hard secondary carbides dispersed in an austenite matrix. The hardfacing components are suitable to apply in

extremely severe abrasion wear and heavy impact up to 572°F (300 °C). The overlay provides 2 to 3 times longer service life than DuroxiteTM 100.  It offers in both plate and pipe.

Bulk hardness: 60 to 65 HRC Carbide hardness: 2000 HK

Volume fraction of carbides: 30-50% ASTM G65-Procedure A weight loss: 0.12g max.

Buckets and teeth, sizing screens, railway ballast tampers, coke hammers, dredge buckets and lips, dragline buckets, rippers, crushing equipment, brick industry components, Muller tyres, catalyst lift pipes, pump impellers, fan blades, rockwool rolls, wear plates

operating at high temperature in the steelmaking industry.

DuroxiteTM 210 DuroxiteTM 210 applies specially formulated abrasive materials depositing on mild steel backing plate subject to extremely severe abrasive wear and moderate impact up to 1112°F (600°C). The longer service life would be offerred compared to DuroxiteTM 200. It offers in both plate and pipe. Bulk hardness: 60 to 65 HRC Carbide hardness: 2500-3000 HK

Volume fraction of carbides: 30-50% ASTM G65-Procedure A weight loss: 0.12g max.

Cement furnace components, sinter plant parts, fan blades, mixer blades, crews, Gyratory mantles, coal & cement pulverizer rolls & grinding, Ore sintering, crushing, riddling, blast furnace hoppers and throats, ovens
DuroxiteTM 201 DuroxiteTM 201 overlay is composed of a high concentraion primary chromium carbides and secondary carbides

deposition on Q&T steel backing. Besides the same wear properties as DuroxiteTM 200, DuroxiteTM 201 also provides better impact resistance and greater safety margin than DuroxiteTM 200.

Bulk hardness: 60 to 65 HRC Carbide hardness: 2000 HK

Volume fraction of carbides: 30-50% ASTM G65-Procedure A weight loss: 0.12g max.

Loader bucket liner, feeding system for ball mill
DuroxiteTM 211 DuroxiteTM 211 overlay contains primary chromium carbides and refined multiple- alloys complex carbides in an austenite matrix which is deposited on Q&T

steel backing. Besides the same wear properties as DuroxiteTM 210, DuroxiteTM 211 also provides better impact resistance and greater safety margin than DuroxiteTM 210.

Bulk hardness: 60 to 65 HRC Carbide hardness: 2500-3000 HK

Volume fraction of carbides: 30-50% ASTM G65-Procedure A weight loss: 0.12g max.
