Steel manufacturer and supplier, SSAB, has designed the Hardox HiAce range of steel, which is suitable for severe conditions.
Engineered for applications in acidic and corrosive environments, Hardox HiAce abrasion-resistant steel is used as a structural material in garbage trucks, recycling containers, tipper and dump bodies, and other heavy-duty equipment.
A 2019 report found that Australia produced 7.5 million tonnes of hazardous waste in a two-year period, which was a 34 per cent uptick on the previous generation and represented 11 per cent of all waste generated nationwide. This number is only rising as Australia grapples with increasing volumes of e-Waste: 290,000 tonnes of e-waste material has been diverted to landfills to date, and an additional 100,000 tonnes of solar panel waste is forecast to enter the waste stream by 2035.
In these environments, the steel in truck and tipper bodies, containers and other equipment can come under attack from different types of acids, which have low pH levels, salt-containing chlorides, or sulphates that can lead to general corrosion. This acidity oxidises the steel’s surface, making it more prone to wear. Therefore, Australian businesses require tougher equipments to protect profitability, equipment condition, service life, and the environment.
Hardox HiAce has been developed to withstand challenges posed to steel in waste recovery and recycling. The corrosion-resistant steel plate slows down the oxidation process, allowing the hardness of the material to counteract wear. Hardox HiAce performs the same as 450 HBW steel in pH-neutral environments. In low pH levels, it can extend equipment service life up to 3 times longer compared to 400 HBW steel.
Hardox HiAce’s increased wear resistance also allows for the use of thinner plates without jeopardising service life — translating to more payload when fully loaded and, when traveling empty, more fuel savings and fewer CO2 emissions.
