The dump body in the pictures is made with Hardox 500 Tuf in the bottom plate. It has transported more than 88 million lbs. of crushed rock for more than a year with very low wear. Measuring the thickness at the end section of the 0.236 in. (6 mm) bottom plate showed an average wear of only 5 percent.
The Hardox 500 Tuf combines the best properties from Hardox 450 and Hardox 500, giving it exceptional strength, hardness and toughness in one and the same wear plate, according to the manufacturer.
Hardox 500 Tuf is tough enough to perform as a structural material in heavy-duty dump bodies, and its performance also is proven in cold climates and freezing conditions. Superior wear and dent resistance allow for increased service life and the ability to withstand heavy impact.
Typical working conditions include loading and unloading of heavy and sharp rocks in quarries and mines.
Twice the Service Life Possible
85 to 100 percent longer estimated service life compared to Hardox 400 (SSAB's WearCalc and TippCalc calculations based on sliding wear with granite)
Guaranteed impact energy of 20 ft.-lb. at minus 4 F (27 J at minus 20 C)
Narrow Brinell hardness window of 475 to 505 HBW
Highly dent and crack resistant when hit by sharp and heavy objects
