What is a Hardox 450 Weight Calculator?
A Hardox 450 weight calculator is an essential engineering and procurement tool designed to estimate the mass of abrasion-resistant (AR) steel plates. Hardox 450, manufactured by SSAB, is the industry standard for wear-resistant steel, known for its consistent hardness of roughly 450 HBW (Brinell Hardness). Because this material is sold by weight and used in applications where payload and structural load are critical, calculating the exact weight is vital for budgeting and design.
This calculator is specifically tailored for engineers, fabricators, and project managers who need to determine the logistics of shipping, the cost of raw materials, or the impact of the liner weight on heavy machinery like dump trucks and excavators.
Hardox 450 Formula and Mathematical Explanation
The calculation for the weight of Hardox 450 follows the standard physics formula for the mass of a rectangular prism, utilizing the specific density of steel. Although Hardox is a specialized alloy, its density is virtually identical to standard carbon steel.
Where the density factor for steel is typically 7.85 when thickness is in millimeters and area is in square meters.

Practical Examples (Real-World Use Cases)
Example 1: Dump Truck Bed Liner
A fabrication shop needs to reline the floor of a mining dump truck. They require 4 sheets of Hardox 450 to cover the area.
Dimensions: 6000mm (L) x 2500mm (W) x 12mm (T)
Calculation: 6.0m × 2.5m × 12mm × 7.85 = 1,413 kg per sheet.
Total Weight: 1,413 kg × 4 sheets = 5,652 kg.
Financial Impact: At a hypothetical price of $2.50/kg, the material cost is $14,130.
Example 2: Crusher Chute Wear Strips
A maintenance team is cutting smaller wear strips from a larger plate.
Dimensions: 500mm (L) x 200mm (W) x 20mm (T)
Calculation: 0.5m × 0.2m × 20mm × 7.85 = 15.7 kg per strip.
Quantity: 50 strips.
Total Weight: 785 kg.

Key Factors That Affect Hardox 450 Results
When using a Hardox 450 weight calculator, consider these six factors that can influence your final figures:
Thickness Tolerance: Steel plates have manufacturing tolerances. A "10mm" plate might actually be 10.3mm, slightly increasing the actual weight.
Cutting Kerf: If you are calculating the weight of a finished part cut from a plate, remember that the calculator assumes a perfect rectangle. It does not account for material lost during plasma or laser cutting.
Weld Material: If you are welding multiple Hardox plates together, the weight of the weld wire adds to the total assembly mass.
Scrap Rate: When buying full sheets to cut specific shapes, you pay for the full sheet weight, not just the finished part weight. This is a critical financial distinction.
Shipping Costs: Since Hardox is heavy, freight is a major cost factor. Accurate weight calculation ensures you don't overload trucks or underestimate shipping fees.
Price Fluctuations: The price of steel changes weekly based on global scrap markets and alloy surcharges. Always update the "Price per kg" field for current accuracy.
Frequently Asked Questions (FAQ)
What is the density of Hardox 450?
The density of Hardox 450 is approximately 7.85 g/cm³ (7850 kg/m³). This is the standard density used for most carbon and low-alloy steels.
Is Hardox 450 heavier than mild steel?
No. Hardox 450 is significantly harder and stronger than mild steel, but its density (weight per volume) is effectively the same. However, because it is stronger, you can often use a thinner plate of Hardox to achieve the same structural performance, reducing overall weight.
Can I use this calculator for Hardox 500 or 600?
Yes. The density of Hardox 500, 550, and 600 is also approximately 7.85 g/cm³. You can use this tool for any grade of steel plate.
Why is accurate weight calculation important for dump trucks?
Every kilogram of steel liner reduces the payload capacity of the truck. Using a precise Hardox 450 weight calculator helps engineers balance wear life (thicker plate) against payload efficiency (thinner plate).
Does this calculator account for holes or cutouts?
No, this calculator assumes a solid rectangular plate. If your design has significant cutouts, calculate the full rectangle and then subtract the weight of the cutouts manually.
What are the standard sheet sizes for Hardox?
Common sizes include 2000x6000mm, 2500x6000mm, and 2500x8000mm. However, SSAB and distributors can cut to custom lengths.
How do I calculate the cost of a Hardox plate?
Multiply the total weight (kg) by the current market price per kg. Our calculator includes a field to do this automatically.
Is Hardox 450 magnetic?
Yes, Hardox 450 is a ferritic steel and is magnetic, which is useful for magnetic lifting during fabrication.
