HARDOX-450 is a wear resistant steel grade with a hardness of HBW. Unique for this steel grade is its combination of toughness & hardness without compromising the
characteristic HARDOX easy in the workshop. HARDOX-450 wear plate meets strickly demands on wear resistance. Its great hardness, high strength & brilliant toughness makes the material well suited
for a wide variety of application. Its toughness is very high even under difficult conditions, such as a high rates of strain combined with low temperatures. This makes HARDOX-450 particularly
resistant to impact.
