1. What is Density of EN9 Material?

Definition: Density is the mass per unit volume of EN9 steel, a medium carbon steel alloy commonly used in engineering applications.

Typical Value: EN9 steel has a density of approximately 7850 kg/m³ at room temperature.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of the material is divided by its volume to calculate its density.

3. Importance of Density Calculation

Details: Knowing the density of EN9 material is crucial for weight calculations, structural design, and material selection in engineering projects.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is EN9 steel?
A: EN9 is a medium carbon steel with good tensile strength, often used for shafts, gears, and high-strength components.

Q2: Why is density important for EN9 material?
A: Density affects weight calculations, structural load capacity, and material costs in projects.

Q3: Does temperature affect EN9 density?
A: Yes, like all materials, density decreases slightly with increasing temperature due to thermal expansion.

Q4: How does EN9 density compare to other materials?
A: EN9 (7850 kg/m³) is similar to other steels, denser than aluminum (~2700 kg/m³), but less dense than lead (11340 kg/m³).

Q5: Can I use this for other materials?
A: The formula works for any material, but the default density value is specific to EN9 steel.
