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 said. Raex special steel is made in a range of thicknesses from two-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.
