November 18, 2019 - Duroxite® 500 is the latest addition to the range of Duroxite® overlay products. It is designed for applications involving abrasive wear and high impact in dry and wet environments.
Duroxite® 500 can replace cast materials, titanium carbide overlay products or ceramic materials. Duroxite® 500 is suitable for use in a wide range of industries, including mining, power generation, cement, oil sand, steel production, waste handling, agriculture, and pulp and paper. The applications suitable for Duroxite® 500 involve rock sizes of up to around 0.5 m x 0.5 m dropping from 5 m or lower.
Ultra-fine complex borocarbides stand up to impact
Duroxite® 500 overlay contains complex borocarbides that are 200 times finer than chromium carbides. The complex borocarbides prevent spalling and cracking when exposed to high impact. Lab testing shows that the impact resistance of Duroxite® 500 can be up to 6 times higher than chromium carbide overlays.
3 times longer wear life in copper mine
When replacing the cast Mn liner plate with Duroxite® 500 in the belt machine head, wear life increased from 15 to 45 days. 2,700,000 tons of copper ore was processed before maintenance compared to 900,000 tons for the cast liner.
High hardness also at high temperatures
Duroxite® 500 has a uniform through-thickness hardness of 67 to 70 HRC for single and multiple-layer overlays. It maintains a high hardness of approximately 60 HRC after exposure to temperatures up to 600°C (1100 °F).
Guaranteed overlay properties
The wear properties of Duroxite® 500 are guaranteed throughout the overlay down to 75% of the overlay thickness. The remaining 25% of overlay is the transition layer necessary to maintain good bonding to the backing plate.
Guaranteed maximum weight loss
SSAB is the only supplier that guarantees a maximum weight loss for overlay products according to the ASTM G65-Procedure A test. With a tested maximum weight loss of 0.18 g, Duroxite® 500 meets the high standards set by the customers.
Worldwide availability
Duroxite® 500 is available through Hardox Wearparts, the global network of wear service centers. Today the network includes more than 500 centers in over 90 countries. All centers can be found here >
