Product Profile

Hardox HiAce meets challenging environments

The Hardox wear plate product range of abrasion-resistant steel has a reputation for being both hard and tough, fighting wear in severe conditions. Hardox HiAce is the latest product in the range, targeted at applications in acidic and corrosive environments.

The recycling business poses particular challenges to steel. Municipal solid waste, often referred to simply as garbage, is one example of a material that creates a low pH acidic environment that accelerates wear in garbage truck bodies and refuse containers. Other conditions that have the same effect are when transporting wood chips if chemicals such as sulphates and chlorides are present.

Hardox HiAce has been developed to withstand these conditions. At low pH levels, the wear mechanism is different than in a more pH-neutral environment. The acidity oxidises the steel’s surface, making it more prone to wear even if the body or container is made with a hard material.

Hardox HiAce introduces new opportunities to fight acidity and corrosion.

Hardox HiAce slows down the oxidation process, allowing the full hardness of the material to counteract wear. 

In a regular environment, Hardox HiAce will perform the same as a 450 HBW steel. But in conditions with lower pH levels, the equipment service life is up to three times longer compared to a 400 HBW steel.

Apart from the additional wear resistance in acidic environments, Hardox HiAce has the toughness it takes to perform as a structural material in garbage trucks, recycling containers, tipper and dump bodies and other heavy-duty equipment.

Hardox HiAce also works in freezing conditions, with a guaranteed impact energy of 27 J at -20 °C. It is available in thicknesses of 4-25.4 mm. It has similar mechanical properties as Hardox 450. It can be processed by the same kind of machinery used for Hardi Hardox grades.

The increased wear resistance in garbage trucks and other equipment allows for the use of thinner plate without jeopardising the service life. A thinner steel plate means more payload when fully loaded. And when traveling empty, a lower-weight truck saves on fuel and reduces CO2 emissions.
