Grade Brief
EN8 is an unalloyed medium carbon steel known for its high strength, durability, and good resistance to wear and temperature. It is widely used in general-purpose engineering applications where alloy steels are not economically justified. Compared to alloy steels, EN8 offers a more cost-effective solution while still providing dependable mechanical performance.
Key Features
- Material Type: Medium Carbon, Unalloyed Steel
- Strength: High tensile strength with good toughness
- Surface Properties: Excellent surface hardness with moderate wear resistance when flame or induction hardened
- Heat Treatment: Can be heat-treated to achieve higher hardness and tensile strength
- Machining: Good machinability; weldability is fair (precautions required)
- Cost Efficiency: Lower cost than alloy steels with sufficient strength for standard applications
Product Forms
- Bright Bars: EN8D Carbon Steel Bright Bars are available for improved dimensional accuracy and surface finish
- Ground Bars: Precision-ground or surface-ground rods supplied as per customer specifications
- Cut-to-Size: Bars available in round, square, flat, and hexagonal profiles, cut to required dimensions

|---|---|---|
| Normalizing | 830 – 860 | Air cool |
| Annealing | 680 – 700 | Furnace cool |
| Hardening | 820 – 860 | Oil or water quench |
| Tempering | 550 – 660 | To required hardness/strength |
Application
Shafts & axles, Studs & bolts, Gears & machine parts, Automotive and general engineering components
Conclusion
EN8 medium carbon steel is the best and cheapest alloy option for various engineers and automotive applications. Its combination of strength and hardness makes this grade a rather effective wear resistance, with quite good performance without exorbitant costs for alloy steels. It has thermal versatility and is manufactured into different product forms applicable for use in shafts, gears, bolts, and machines, and so suitable for wear during long-term or harsh conditions.
