Hardox
Hardox is a very wear-resistant sheet steel. Hardox is also called wear plate. This fact is especially interesting for companies that quarry gravel and sand as, for example, excavator buckets or dump truck bodies made from HARDOX last fast longer.
A comparison of different Hardox grades:
HARDOX 400
- Sheet thickness 3 – 130 mm
- Brinell hardness 370 – 430
HARDOX 450
- Sheet thickness 3 – 80 mm
- Brinell hardness 425 – 475
These are used if a combination of high wear resistance and good cold working properties is required. These sheets and plates are used, for example, to produce dumper trucks, screens, chutes, rock crushing machines, excavators and conveyors. These steel grades are characterised by their very good weldability.
HARDOX 500
- Sheet thickness 4 – 32 mm
- Brinell hardness 470 – 530
- Sheet thickness 32 – 80 mm
- Brinell hardness 370 – 430
HARDOX 550
- Sheet thickness 10 – 50 mm
- Brinell hardness 525 – 575
These are used if high requirements are necessary with regard to wear resistance.
These sheets and plates are used, for example, to make conveyors, blades and cutters, buckets for excavators, gear wheels and crushing plants.
The material must not be heated above 250°C, as otherwise the sheet or plate can lose its outstanding properties.
Hardox 600
- Sheet thickness 8 – 50 mm
- Brinell hardness 560 – 640
This is used if high requirements are necessary with regard to wear resistance. This sheet / plate is used, for example, to make chutes, crushers, hammers and shredders.
Hardox HiTuf
- Sheet thickness 40 – 120 mm
- Brinell hardness 310 – 370
This is used if extremely high requirements are necessary with regard to toughness (ductility) and wear resistance. It is used to make, for example, demolition tools and cutting edges.
Hardox Extreme
- Sheet thickness 10 mm
- Brinell hardness 700
- Sheet thickness 25 mm
- Brinell hardness 650
This is used if extremely high requirements are necessary with regard to wear resistance.
This sheet / plate is used, for example, to make hammers, crushers, wear protection plate (armour plate) cutting equipment.
