Hardox® 500 Tuf
Hardox® 500 Tuf wear plate, the latest grade in the Hardox range, delivers exceptional strength, hardness and toughness in a single plate, guaranteed. It has proven its value around the world in tipper and dump bodies, containers, mining equipment, agricultural machinery, liners and wear parts, and buckets of all kinds. Explore the heavy wear fighter Hardox® 500 Tuf!
More payload
How come a tipper body or bucket in Hardox® 500 Tuf steel can deliver more payload? Simply because it can make equipment lighter through thinner dimensions and less heavy wear packages while maintaining its high durability.
Longer service life
With Hardox® 500 Tuf you can expect twice the service life compared to a 400 HBW AR steel, and up to 50% longer service life relative to a 450 HBW steel. Look forward to savings in repair and maintenance costs.
Tippers and dump bodies load more and last longer with Hardox® 500 Tuf
Want to take your business to the stratosphere? Get lighter bodies with the wear resistance of heavier structures? Reduce or eliminate supporting structures? That’s what OEM Mantella did. Discover how they saved 365 kg (805 lbs.) in their Stratosphere trailer body. With a lower tare weight, your bodies can carry more payload, use less fuel per ton transported and make fewer trips on the road.
Increase payload and service life for buckets, dippers and attachments in Hardox® 500 Tuf
If you want productivity gains, nothing beats the combo of high strength, hardness and toughness that Hardox® 500 Tuf brings. And you won’t get bogged down with heavy wear packages or costly repairs because your attachments will last longer – potentially, up to 100% longer compared to using a 400 Brinell steel or conventional AR steel. Find out how Swedish Fronteq and Danish Sjørring improve the productivity and wear life of their buckets.
Hardox® 500 Tuf for high productivity in mining
Can your valuable mining equipment take a pounding every day and still reach high levels of productivity and profitability? Schlam knows that it can, with a boost in loading capacity of up to 20%. You too can protect your investments with Hardox® 500 Tuf in mining haul truck bodies. It has a guaranteed narrow Brinell hardness range of 475-505 HBW, an impact energy of 27 J at -20°C (20 ft-lb at -4°F) and a typical value of 50 J at -40°C (37 ft-lb at -40°F), making it the optimal choice in cold conditions.
Hardox® 500 Tuf is a recycling champion
Containers made of Hardox® 500 Tuf are light and strong and stand up to the harshest recycling challenges. The Finnish company Ferreus turned to Hardox® 500 Tuf and saved more than one tonne (1.1 tons) in container weight. Heavy and sharp materials like steel scrap, concrete rebar and demolition scrap are no match for Hardox® 500 Tuf. The recycling container is ready to handle the toughest of loads and still return in good shape at the end of the day.
Hardox® 500 Tuf keeps concrete mixers rolling
Using Hardox® 500 Tuf in concrete mixers makes them lighter and more durable. The German company Stetter knows this firsthand, since it was able to the cut weight of its mixer drums. The additional hardness Hardox® 500 Tuf gives, compared to Hardox® 400 and Hardox® 450, allows for thinner dimensions that reduce drum weight with the same high wear life. Alternatively, if you keep the same thickness the drum lasts longer. Either way, Hardox® 500 Tuf makes any concrete mixer drum more competitive.
Dimension Range
Hardox® 500 Tuf is available as sheet in thicknesses of 3.0 – 6.5 mm, and as plate in thicknesses of 4.0 – 38.1 mm. More detailed information on dimensions is provided in the dimension program.

1) Brinell hardness, HBW, according to EN ISO 6506-1, on a milled surface 0.5 – 3 mm below surface. At least one test specimen per heat and 40 tons. The nominal thickness of supplied plates will not deviate more than +/- 15 mm from the thickness of the test specimen used for hardness testing. For sheet the Brinell hardness test is according to EN ISO 6506-1 on each heat treatment individual/coil. Hardness is measured on a milled surface 0.3 – 2 mm below surface.
Hardox® wear plate is through-hardened. Minimum core hardness is 90 % of the guaranteed minimum hardness.
Impact Properties
1) Impact testing is performed on thicknesses ≥ 6 mm for plate and ≥ 3 mm for sheet. For thicknesses between 3 and 11.9 mm, sub-size Charpy V-specimens are used. The specified minimum value is proportional to the cross-sectional area of the test specimen, compared to a full-size specimen (10 x 10 mm). Impact testing according to ISO EN 148 per heat and thickness group. Average of three tests.
2) Typical value for 20 mm.
