| Duroxite 300 is an iron-based steel alloy overlay deposited on a mild steel backing plate. It is designed for extremely severe sliding wear for both dry and wet (slurry) abrasive environments. It works well at ambient or elevated temperatures up to 1100°F (600°C). The product is available in single and double layers. Duroxite 300 consists of specially formulated abrasive materials employing a uniform glass-forming melt chemistry that allows high undercooling to be achieved. The overlay contains a unique high volume of ultra-fine tungsten-niobium-molybdenum-rich complex borocarbides with a grain size refined down to 500 nm. The borocarbides are completely wetted in a ductile matrix preventing premature pull-out delamination, crack nucleation and bridging. This results in a product with significantly improved service life that maintains high toughness in severe sliding wear applications. Duroxite 300 is an excellent alternative to tungsten carbide overlay. Key Benefits - Extreme wear resistance in dry and wet abrasive environments with a high degree of toughness.
- Cost effective alternative to tungsten carbide with equivalent service life and better impact resistance.
- Overlay thickness is reduced compared to traditional overlays resulting in a lighter weight product while increasing service life.
- Absorbs 25% more impact energy than the traditional chromium overlay plate as measured by the continuous high impact lab test.
- Has uniform through-thickness hardness of 67 to 70 HRC for single and multiple-layer overlay.
- Maintains a high hardness of approximately 60 HRC after exposure to high temperatures up to 1100°F (600°C).
- Maintains a consistent wear resistance from surface down to 75% of the overlay.
