There are numerous types of steel in the globe, and the strength is governed by the chemical composition. Hardox is one of them. Hardox is available in a variety of grades, for example, Hardox 400,450,500,600 in sheets and plates.
When compared to conventional steel, this form of steel reduces weight and increases the service life of steel structures. Hardox steel products can be recycled into new, stronger, and more energy-efficient components. Because of its unique combination of qualities such as toughness, hardness, and strength, this steel can be utilised to create thinner plates.
Materials utilised to construct machines in the 1980s did not provide the requisite stability. As a result, material consumption was reduced, and machine parts required to be improved on a regular basis. This was the impetus behind the introduction of hardox steel in 1970.
Hardox steels are distinguished primarily by the following characteristics:
→ High resistance to wear friction
→ Good ductility
The main disadvantage of hardox steel is its low corrosion resistance, which limits its use in harsh situations.
Hardox achieves its excellent strength capabilities due to an adequate alloying additive composition (low content of hazardous elements such as S and P) at a significantly lower price when compared to other structural steels. Hardox steel varies according to species, plate thickness, carbon concentration, and alloying components (Ni, B, Cr, Mo, Mn).
Hardox 400 is utilised in applications involving the lengthening of working hours and the increase of capacity in elements such as loaders, bulldozers, buckets, and trays. The desired hardness range (370–430 HBW) is attained by quenching and tempering.
Hardox 450 is a material used in numerous industries as a component in crushers, containers, sieves, hoppers, dump trucks, excavators, and so on. Increasing the hardness to 425–475 HBW increases component durability by up to 50% when compared to hardox 400.
Hardox 500 hardness varies with plate thickness, with a range of 470–530 HBW for 4–32 mm and 450–540 HBW for 32–103 mm. It can be found in flooring crushers and plough mixers. This steel is easily welded.
Hardox 600 steel has exceptional impact resistance, hardness, and ductility while keeping the ability to bond metal plates using traditional welding procedures. This steel is known as “high-quality abrasion-resistant steel.” In comparison to other types of hardox, Hardox 600 is solely intended for applications involving abrasive wear of the base material and is not suited for conventional structural applications.
