EN8 is a medium-carbon steel grade that is known for its excellent strength, wear resistance, and machinability. These round bars are widely used in manufacturing, automotive, and construction industries. Understanding the weight of EN8 round bars is crucial for precise applications, cost calculations, and transportation logistics.
In this blog, we provide a detailed EN8 round bar weight chart, explain its calculation, and highlight its applications and advantages.
Understanding the EN8 Round Bar Weight Chart
A weight chart is a quick reference guide that helps you determine the weight of EN8 round bars based on their diameter and length. Weight charts are essential for selecting the right material for your project and managing inventory efficiently.
Below is the standard EN8 round bar weight chart:
| Diameter (mm) | Weight per Meter (kg) |
|---|---|
| 10 | 0.62 |
| 12 | 0.89 |
| 16 | 1.58 |
| 20 | 2.47 |
| 25 | 3.85 |
| 32 | 6.31 |
| 40 | 9.86 |
| 50 | 15.41 |
| 63 | 24.56 |
| 80 | 39.42 |
How to Calculate the Weight of an EN8 Round Bar
The formula for calculating the weight of a round bar is as follows:
Weight (kg) = (π/4) × D² × L × Density
- D: Diameter of the bar (in meters)
- L: Length of the bar (in meters)
- Density: Material density (EN8 steel has a density of approximately 7.85 g/cm³ or 7850 kg/m³)
Example Calculation
Let’s calculate the weight of an EN8 round bar with:
- Diameter = 40 mm (0.04 meters)
- Length = 2 meters
Weight = (π/4) × (0.04)² × 2 × 7850
Weight ≈ 9.87 kg
This value aligns with the weight chart for a 40 mm diameter bar.
