Hardox 500 Tuf

Introducing the new generation Hardox wear plate

Hardox 500Tuf wear plate is the latest upgrade in the Hardox range. It delivers high strength, extreme hardness and guaranteed toughness in one and the same wear plate. Hardox 500Tuf combines the best properties from Hardox 450 and Hardox 500. The result is a wear plate with no real competition on the market.

Hardox 500 Tuf
Mechanical Properties
Hardness 1) (HBW) Typical yield strength (MPa), not guaranteed
4.0 - 25.4 475 - 505 1250 - 1400

1) Brinell hardness, HBW, according to EN ISO 6506-1, on a milled surface 0.5 – 3 mm below surface. At least one test specimen per heat and 40 tons.

The nominal thickness of supplied plates will not deviate more than +/- 15 mm from the thickness of the test specimen used for hardness testing.

Hardox is through-hardened. Minimum core hardness is 90 % of the guaranteed minimum surface hardness.

Impact Properties

Grade Longitudinal test, typical impact energy, Charpy V 10x10 mm test specimen.
Hardox 500 Tuf 1) 27J / -20°C

1)  Impact toughness measured upon agreement. For thicknesses between 6 - 11.9 mm, subsize Charpy V-specimens are used. The specified toughness is then proportional to the cross-sectional area of the test specimen, compared to a full-size specimen (10 x 10 mm). Impact testing according to ISO EN 148. Average of three tests.
