EN8 carbon steel is used in a variety of general engineering applications, including axles, shafts, gears, bolts, and studs. It's also used in automotive components. Why is EN8 carbon steel used?

Strength: EN8 is a medium strength steel with good tensile strength. It's used when higher strength than mild steel is required. 

Cost: EN8 is a good alternative to stainless steel when better mechanical properties than mild steel are required but the cost of stainless steel is not justified. 

Heat treatment: EN8 can be heat treated to improve surface hardness and wear resistance. 

Machinability: EN8 is popular for its machinability. 

Other properties of EN8 carbon steel 

EN8 is also known as 080M40.

EN8 has decent thermal conductivity.

EN8 can be supplied as normalized or rolled.

EN8 can be supplied in the form of round drawn/turned, round hot rolled, hexagon, square, flats, and plate.

Yield Strength: The yield strength of EN8 steel can vary depending on the condition, with normalized conditions typically showing a minimum of 245 MPa, while quenched and tempered conditions can achieve 465 MPa or higher. 3. Elongation: generally has an elongation of at least 16%, indicating its ability to deform under stress without fracturing. 4. Hardness: The hardness of measured in Brinell hardness (HBW), can range from 152-255, depending on the heat treatment. 5. Impact Resistance: has good impact resistance, with values ranging from 20 to 34 Joules (ISO V Impact) depending on the heat treatment. 6. Other Properties:

• Density: Approximately 7.8 g/cm³. 
• Machinability: Relatively good machinability due to its medium carbon content. 
• Cost-Effectiveness: EN8 steel is more cost-effective than alloy steels, making it a practical choice for many applications.
