Such plates present an interesting mixture of hardness, toughness and weldability. They have a nominal hardness of 450 HBW, and may be used in places where wear performance is an important parameter, i.e., mining equipment, loader trays, and dump truck liners, hoppers, crushers, and bulldozer cutting edges. The plates are also very effective in construction, agricultural, cement and quarrying sector.

One more advantage of the ROCKHARD 450 steel is its excellent form and machinability offered to the manufacturers and the fabricators as a great solution. Plates may be cut, drilled, and welded in ordinary ways after which their structural integrity can not be jeopardised. They are extremely hard and still have a significant degree of toughness and ductility making them reliable even during dynamic loads or in low-temperature scenarios.
