Hardox® 500 Tuf
Wear-resistant sheet steel of a new generation for dump trailers, mining and agricultural dump bodies, buckets, containers and other equipment subject to increased wear.
The Hardox product line has been replenished with a new item – the wear-resistant Hardox® 500 Tuf steel. This steel is endowed with high strength, guaranteed hardness and impact toughness.
This is a new material in the Hardox line, but it has proven itself well around the world when used in the construction of containers, quarry and other dump bodies, all kinds of buckets, agricultural machinery, linings and wear-resistant components. Hardox® 500 Tuf wear-resistant steel combines the best properties of Hardox® 450 and Hardox® 500 steels. What is the result? The new wear-resistant sheet steel is unmatched on the market.
An exceptional retrofit tool! Learn about the essential benefits of Hardox® 500 Tuf steel
Hardox® 500 Tuf steel increases productivity and economic efficiency in the mining industry. Unlike other grades of steel, the Hardox® 500 Tuf material combines high impact toughness with guaranteed hardness in the range of 475 to 505 Brinell units.
Size series
Hardox® 500 Tuf steel is supplied in the form of rolled sheets with a thickness of 4.0 – 25.4 mm and in sheets with a thickness of 3.0 – 6.0 mm. To familiarize yourself with the type sizes in more detail, see

Mechanical properties
Mechanical properties
| Steel brand | Thickness (mm) | Hardness (HBW) | Typical value of yield strength (MPa), without guarantee |
| Rolled roll Hardox® 500 Tuf | 3.0 – 6.0 | 475 – 505 | 1250 – 1400 |
| Wide Rolled sheet Hardox® 500 Tuf | 4.0 – 25.4 | 475 – 505 | 1250 – 1400 |
1) Brinell hardness (HBW) according to EN ISO 6506-1 on a surface milled 0.5 – 3 mm deep. At least one test sample from each melt and for every 40 tons.
The limit deviation of the thickness of the test sample does not differ from the nominal thickness of the material.
Hardox® 500 Tuf steel is hardened throughout its thickness. The hardness in the center is at least 90% of the guaranteed surface hardness.
Indicators of impact viscosity
| Brand | Guaranteed impact performance for a 10x10mm cross-section with a V-notch 1). |
| Wide Rolled sheet Hardox® 500 Tuf | 27 J/ -20oC |
| Rolled roll Hardox® 500 Tuf | 27 J/ -40 oC |
1) Impact tests are carried out with a sheet thickness of ≥ 6 mm for rolled sheet steel and rolled steel with a thickness of ≥ 3 mm. With a thickness in the range of 3 – 11.9 mm, reduced Sharpie samples with a V-shaped incision are used. The specified impact strength is calculated in proportion to the cross-sectional area of the test sample compared to the full-size sample (10 x 10 mm). Impact tests are performed according to ISO EN 148. Average of three tests.

Tolerances
Thickness
Tolerances correspond to the guaranteed thickness parameters of Hardox® steel. The guaranteed parameters of the Hardox® steel wide sheets meet the requirements of the EN 10 029 class A standard, and the rolled products meet ½ the requirements of the EN 10 051 standard.
Length and width
According to the SSAB company range. Flat sheet tolerances meet SSAB’s standards for sheet metal with uncut edges, which in turn meet the requirements of EN 10029. Roll tolerances meet EN 10051 standards. Products with tighter tolerances can be supplied on request.
Form
Tolerances of broad-sheet products meet the requirements of the EN 10029 standard, and of rolled products – according to the EN 10051 standard.
Flatness
The tolerances correspond to the guaranteed flatness parameters of Hardox® steel class D, which exceed the requirements of EN 10029. The flatness tolerances of coils correspond to the guaranteed parameters of Hardox® steel class A, which are stricter than the tolerances according to the EN 10 051 standard.
Surface quality
In accordance with the requirements of the standard EN 10 163-2 for class A, subclass 1.
Flexible
The flatness tolerances of flat sheets correspond to the guaranteed parameters of Hardox® steel according to class F, which exceed the requirements of the EN 10 029 standard. The flatness tolerances of rolled products correspond to the guaranteed parameters of Hardox® steel according to class B, which are stricter than the tolerances according to the EN standard.
