Longer Wear Life on Haulage Road Compactor
NanoSteel Hardfacing Provides Better Price/Performance Ratio as an alternative to 500 BHN Q&T Plate
At a copper ore surface mine in the southwest United States, vibratory compactors push waste rock into the haulage road to provide a clean level surface for preventing costly tire punctures and other damage to haul trucks, loaders, excavators and other mine vehicles.
Brinell 500 quench & temper (Q&T) liner plate installed to prolong the life of the carbon steel compactor drums is prone to cracking and premature failure due to the extreme hardness of the rock at this mine.
NanoSteel SHS 9700 overlay is applied as hardfacing to a 3/16” or 0.187 in (5 mm) average thickness in a crosshatch pattern directly to the OD surface of the 1.575 in (40 mm) thick carbon steel compactor drums for wear resistance, traction and to help grip the waste rock.
The NanoSteel SHS 9700 overlay hardfacing provides longer wear life, is easier to repair and requires fewer man hours to maintain. Due to the high hardness (67-70 HRc), toughness and wear resistance provided by NanoSteel SHS 9700, the mine can apply a crosshatch hardfacing pattern over a smaller percentage of the drum surface. This requires less overlay material and fewer man hours to apply, resulting in a better price/performance ratio than Brinell 500 Q&T liner plate.

Superior Wear Life from NanoSteel
NanoSteel weld overlay hardfacing provides high hardness (67-70 HRc) and high wear resistance which results in longer service life than Brinell 500 Q&T plate
