Physical properties:

1. Density: Usually around 7.85 g/cm³, which gives it a relatively high mass for a given volume.

2. Electrical Conductivity: It has moderate electrical conductivity but is less conductive than metals like copper.

3. Thermal Conductivity: Good thermal conductivity, allowing it to transfer heat efficiently.

4. Hardness: Varies depending on the carbon content and heat treatment; higher carbon content leads to increased hardness.


Chemical properties:

1. Oxidation: Prone to oxidation when exposed to air and moisture, forming iron oxide (rust).

2. Reactivity with Acids: Reacts with strong acids such as hydrochloric acid and sulfuric acid, liberating hydrogen gas.

3. Corrosion Resistance: Generally has limited corrosion resistance and may corrode in aggressive environments.

4. Alloying Behavior: Can be alloyed with other elements to enhance specific properties, such as chromium for improved corrosion resistance.
