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. For sheet the Brinell hardness test is according to EN ISO 6506-1 on each heat treatment individual/coil. Hardness is measured on a milled surface 0.3 - 2 mm below surface.
Hardox® wear plate is through-hardened. Minimum core hardness is 90 % of the guaranteed minimum hardness.

1) Impact testing is performed on thicknesses ≥ 6 mm for plate and ≥ 3 mm for sheet. For thicknesses between 3 and 11.9 mm, sub-size Charpy V-specimens are used. The specified minimum value is 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 per heat and thickness group. Average of three tests.
2) Typical value for 20 mm.

Fabrication and Other Recommendations
Welding, bending and machining
Recommendations can be found in SSABs brochures at www.hardox.com or consult Tech Support.
Bendability for plates are according to Hardox® Bending Guarantees Class E. For sheets the bendability are according to Hardox bending guarantees Class A.
Hardox® wear plate is not intended for further heat treatment. It has obtained its mechanical properties by quenching and when necessary by means of subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 250ºC .
Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
More payload
How come a tipper body or bucket in Hardox® 500 Tuf steel can deliver more payload? Simply because it can make equipment lighter through thinner dimensions and less heavy wear packages while maintaining its high durability.

Hardox® 500 Tuf keeps concrete mixers rolling
Using Hardox® 500 Tuf in concrete mixers makes them lighter and more durable. The German company Stetter knows this firsthand, since it was able to the cut weight of its mixer drums. The additional hardness Hardox® 500 Tuf gives, compared to Hardox® 400 and Hardox® 450, allows for thinner dimensions that reduce drum weight with the same high wear life. Alternatively, if you keep the same thickness the drum lasts longer. Either way, Hardox® 500 Tuf makes any concrete mixer drum more competitive.

Read moreLonger service life for all kinds of abrasive materials
With Hardox® WearCalc software from SSAB, you can calculate and determine the increase in service life of equipment made in Hardox® 500 Tuf compared with generic AR steel with lower hardness values. A calculation based on sliding wear with granite shows:
- 30-50% longer service life than a 450 HBW material
- 85-100% longer service life than a 400 HBW material, the hardness value of many generic AR steels with lower hardness values
Similar calculations can also be performed for other abrasive materials, such as coal, iron ore, limestone, sand, glass and household waste containing metal.
