Description:
Hardness = Wear Resistance
Hardness is what gives Hardox steel its unique wear resistance and structural strength. Hardness minimizes wear since it is difficult for the ‘edges’ of abrasive material to cut into the material. Hardox grades deliver high wear resistance during the plate’s entire service life. Hardness also means it has excellent yield and tensile strength, properties that keep a structure in shape without being deformed.
Toughness = Safety
Toughness is the other strong point of Hardox wear plate. When hardness makes it wear resistant and strong, toughness is what makes it possible to bend, form and weld the material without cracking. If a Hardox wear plate is stressed beyond its yield point and plastically deformed—on purpose in the workshop or when hit by a heavy rock on site—it will resist cracking and if a localized crack should occur, it will resist propagation.
