Grade Brief
EN24 is a high-grade alloy steel recognized for its exceptional strength, toughness, and wear resistance, making it a preferred choice for demanding engineering applications. Its unique balance of ductility and hardness enables reliable performance under heavy stress and impact.
EN24, also known as AISI 4340, is a high-strength alloy steel supplied in the hardened and tempered condition. Renowned for its outstanding toughness, high tensile strength, and wear resistance, EN24 is widely used for manufacturing critical engineering components subjected to heavy stress.
Key Properties
- High tensile strength with excellent fatigue resistance
- Good toughness even at low temperatures
- Superior wear resistance for extended service life
- Excellent machinability in the annealed condition
- Can be hardened and tempered for tailored performance
