Ruukki adds to its range of Raex wear-resistant steels for all applications requiring up to 80-mm thick heavy plate

Rautaruukki Corporation Press release 27 May 2013 at 10.30am EEST

Ruukki can now supply steels for all applications requiring wear-resistant special steels. Ruukki Raex special steel can withstand wear and surface pressure and the range has now been expanded to include the thicker wear-resistant steels needed, for example, in the mining industry. Raex special steel is made in a range of thicknesses from 2 mm to 80 mm.

The new thicker Raex wear-resistant steels up to 80 mm can be used, among other things, to manufacture parts for heavy machinery and equipment designed for excavation, loading, transporting and crushing ore in mines. Such parts include the buckets for excavators and front-end loaders, tipper bodies for heavy earthmoving machinery, mine conveyor systems, crushers, silos and hoppers. The thinner grades in the Raex wear-resistant steel product family have already been used for years in the transportation industry and other applications where a strong, wear resistant steel is needed.

The consistent quality of Raex steels significantly prolongs the lifetime of mining industry machinery and equipment. Products with a longer lifetime mean cost benefits and competitiveness for the end user. Choosing the optimum thickness of Raex wear-resistant steel in the manufacture of buckets and tipper bodies, for instance, can help to reduce the overall weight of the equipment itself and thus increase the payload, which in turn cuts fuel consumption. 

Raex wear-resistant steels have been developed together with Ruukki customers and have excellent cutting, bending and welding properties. Made using a direct quenching method developed by Ruukki, Raex wear-resistant steels have a hard steel surface and strong microstructure. The method improves the properties of wear-resistant steels and makes them consistent in quality. 

New thicker Ruukki Raex steels can be used for example to manufacture parts for heavy plant and equipment designed for excavation, loading, transporting and crushing ore in mines.

The service life time of mining or recycling equipment is longer thanks to excellent mechanical properties of Raex.

Direct quenched Raex wear-resistant steel is made in a range of thicknesses from 2 mm to 80 mm.
