Hardox Plates

Key Applications:

1. Mining and Quarrying:

• Dump Truck Bodies & Liner Plates – Increase payload life under heavy, abrasive rock loads.
• Crusher Liners & Feeder Linings – Withstand repeated impact and abrasive particle flow.
• Dragline Buckets & Shovels – Resist gouging and edge wear under extreme mechanical stress.

2. Cement and Aggregate Handling:

• Hopper Liners & Conveyor Sides – Protect high-wear areas from constant friction and impact.
• Screening Equipment & Impact Walls – Maintain performance during repeated material contact.

3. Construction and Earthmoving:

• Excavator Buckets & Bulldozer Blades – Improve durability in demanding earthwork tasks.
• Wear Strips & Cutting Edges – Prevent premature failure in scraping and grading applications.

4. Recycling & Demolition:

• Shredder Liners & Scrap Bins – Handle tough materials like metal scrap, concrete, and glass.
• Demolition Tools – Offer shock resistance and longevity under severe loading.

Grades and Formats:

Hardox is available in a wide range of grades, including:

• Hardox 400 – Versatile grade for moderate wear and impact.
• Hardox 450 / 500 – High wear resistance for mining and quarrying.
• Hardox 600 – Extra hard plate for extreme abrasion with moderate impact.
• Hardox HiTuf – Special grade with extra impact toughness for structural applications.
• Hardox Extreme – Highest wear resistance in the Hardox family.

Plates are supplied in thicknesses ranging from 0.7 mm to 160 mm, in sheet or custom-cut formats.

Manufacturing Process:

1. Steel Production:

• The process begins with high-purity iron and alloy elements, refined through an advanced steelmaking process.
• The steel is cast and rolled into sheets or plates.

2. Quenching and Tempering:

• The plates undergo quenching, a rapid cooling process that locks the steel’s martensitic structure, dramatically increasing hardness.
• Tempering follows to restore some ductility and reduce internal stresses, ensuring the material retains both strength and toughness.

3. Finishing:

• Plates are leveled, surface treated, and tested for uniform hardness, toughness, and flatness.
• They are then precision-cut into various standard or custom dimensions.

Mechanical Properties:

• Hardness: Ranges from 400 to 650 HBW depending on the grade.
• Tensile Strength: Up to 1,250 MPa, depending on grade and thickness.
• Impact Toughness: Maintains toughness even at sub-zero temperatures (e.g., -40°C for some grades).
• Formability & Weldability: Despite its hardness, Hardox is easy to cut, machine, weld, and form using standard workshop equipment.

Benefits of Hardox Wear Plates:

Exceptional Wear Resistance – Prolongs equipment life in abrasive conditions.
High Impact Toughness – Withstands heavy blows without cracking or failure.
Good Weldability & Machinability – Simplifies fabrication and repair.
Dimensional Consistency – Guaranteed flatness and thickness tolerances.
Structural Capabilities – Can be used as both a wear liner and load-bearing structure.
Versatile Application – Suitable for mobile equipment and stationary installations alike.

Hardox wear plates represent the gold standard in wear-resistant steel—offering unmatched strength, durability, and ease of use. Whether you’re facing abrasion, impact, or heavy mechanical loads, Hardox delivers reliable performance in the harshest industrial environments. Its wide range of grades allows engineers to optimize durability without sacrificing workability, making it a cost-effective and long-lasting choice for critical wear components.
