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.
