EN24 (817M40) combines high tensile strength with toughness & fatigue resistance.

---

Equivalent specifications for EN24 include 817M40, AISI 4340, and 34CrNiMo6.

Overview:

EN24 is a high-strength, low-alloy steel highly suitable for use in demanding operating environments. Fatigue resistance is one of the main features - the material resists the effects of cyclic loading without failure. Including molybdenum and nickel in the production process increase the alloy's ability to resist crack initiation and propagation. The alloy is suitable for motorsport applications requiring high strength, toughness and fatigue resistance but where weight saving is not considered essential.

Fatigue Resistance:

The steel has excellent fatigue resistance - EN24 (817M40) withstands cyclic loading without failing. The high strength and toughness are due to particular elements in the alloying mix (nickel and molybdenum) contributing to these attributes. Resistance to crack initiation and propagation are also notable.

In motorsport:

EN24 is commonly called an 'aerospace-grade' product but has broadened its use into other markets such as oil & gas and motorsport. Typical motorsport applications for EN24 (817M40) include clutch plates, connecting rods, anti-roll bars and fasteners.
