Hardox® Wear Plates

Abrasion Resistant Steel Plates Wear resistant Steel Plates


Due to its high strength, hardness and exceptional wear resistance,  Hardox®abrasion-resistant steel plate is particularly suited to applications such as attachments for excavators and earthmovers, trucks, breakers and crushers, recycling machinery, quarrying machinery, conveyors and materials handling equipment.

Our abrasion-resistant steel stock is available as standard in 8000 x 2000 and 6000 x 2500 plates in a range of thicknesses. We can also supply non-standard sizes, which can help to manage your costs by reducing wastage in the manufacturing process.

What is Hardox® 400?

Hardox® 400 is a trusted steel in the Hardox® wear plate family, with a heritage of hardness and toughness going all the way back to 1974, when Hardox® was launched as the world’s first bendable wear steel. This allowed for reliable performance both in the workshop and in operation. Plates in Hardox® 400 come in thicknesses from 2 to 130 mm (0.079 to 5.118”). This grade is also available as pipes or tubes and round bars.

Hardox® 400 leaves mild steel behind

Mild steel just doesn’t cut it in today’s equipment. It’s not strong enough, or hard enough to deliver the productivity or service life you expect. When you upgrade from steels such as S255, S355, A36, grade 50 or A514, SS400 or S45C to Hardox® 400, you can look forward to stronger and lighter equipment with higher capacity and less maintenance. And you can cut, weld and machine Hardox® 400 using standard techniques and tools. All in all, Hardox® 400 outperforms mild steel, every time.

Hardox® 400 makes friends in the workshop

Hardox® 400 is as easy for fabricators to work as any mild steel. There are several reasons: The steel is very clean and has consistent properties, meaning it behaves in a predictable way every time. It also has a lean chemical composition, which gives it excellent welding properties.

Hardox® 400 can be bent with tight bending radiuses, which sets Hardox® steel apart from other AR steels.

Predictable in welding

Welding of Hardox® 400 is performed with similar welding consumables as for mild steel, without any specific requirements. There is no need for preheating for thicknesses up to 20 mm (0.787”), and any standard welding technique can be used. You can download our welding brochure for more information.

Ready for machining

Any type of machining can be performed with ordinary workshop equipment, such as the common radial drilling machine for drilling and countersinking of Hardox® 400.

As always, you can get technical support and advice from our local technical development managers. We also have a brochure on best practices when machining Hardox® wear plate.


Where is Hardox® 400 used?

Hardox® is a versatile wear steel that’s found in applications practically everywhere, in equipment for roadbuilding, construction, agriculture, quarrying, mining, recycling, cement and concrete production, and more. The steel’s wear performance and toughness in combination with its workshop-friendliness makes Hardox® 400 an industry legend.

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 surface hardness.
