Lighter vehicles and more efficient production with Hardox Strip

Designers in a wide range of industries are on the look-out for steel that is not only stronger and more wear-resistant than standard steel, but also thinner. Applications in the transport industry increasingly call for high-strength, wear-resistant steels to facilitate lighter structures, higher payloads and longer life spans while at the same time offering fuel savings and much lower CO2 emissions.

Hardox Strip can successfully replace wear plates or any other plate material because it has a much cleaner surface, tighter tolerances and higher dimensional accuracy. The thickness tolerances of strip products are approximately one-third of those for heavy plates.

Our Hardox Strip is available in thicknesses of 0.7–8 mm, with hardness levels of 400– 500HB and a maximum width of 1,750 mm.

Tipper bodies must be able to withstand heavy loads on a daily basis. It is typical to use a structural material like S355 with thicknesses of 5–6 mm in tipper bodies. If the material is changed to Hardox 450 wear strip with thicknesses of 2.5–5 mm, the weight of the tipper body is decreased substantially and a higher payload can be used, offering significant cost savings across the entire value chain.

Container manufacturers strive to design containers that are low in weight yet combine high strength with wear resistance. In other words, the lighter the vehicle, the more load it can take. Traditionally, containers have typically been made from S355 with thicknesses of 4-6 mm, which means that the total vehicle weight was approximately 3,000 kg. If the manufacturer designs a new floor plate model using only 2.5 mm-thin Hardox 450, the weight of the container can be reduced to 1,780 kg. This means a higher payload of 1,220 kg with important cost savings over the entire product life cycle.

Other suitable applications that benefit from Hardox Strip products include refuse trucks (2-4 mm Hardox 450) and concrete mixers (3-5 mm Hardox 450).

Thin sheets up to 4,500 mm in width can be produced with a laser-welding process. Production speeds can be increased by 15% thanks to laser-ready welded components from SSAB, thus reducing welding work for the manufacturer. As a bonus there is also less scrap, thanks to customized dimensions.
