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.

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.

Longer service life for all kinds of abrasive materials

With Hardox® WearCalc software from SSAB, you can calculate and determine the increase in service life of equipment made in Hardox® 500 Tuf compared with generic AR steel with lower hardness values. A calculation based on sliding wear with granite shows:

  • 30-50% longer service life than a 450 HBW material
  • 85-100% longer service life than a 400 HBW material, the hardness value of many generic AR steels with lower hardness values

Similar calculations can also be performed for other abrasive materials, such as coal, iron ore, limestone, sand, glass and household waste containing metal.
