What are EN24 Material and why are they a Popular Choice for Marine Applications?

EN24 Steel

Marine applications require sturdy and durable materials that withstand the harsh and corrosive effects of saltwater, harsh weather, and extreme temperatures. En 24 is a type of high-strength, low-alloy steel specifically designed to meet the needs of marine applications. In this blog post, we will explore the properties and benefits of En 24 material and why it is a popular choice in marine engineering.

What is EN24 Material?

EN24 is an alloy steel containing chromium, nickel and molybdenum. It is a heat-treated material normally supplied in hardened and tempered conditions with 32 to 36 HRC hardness. This steel grade is ideal for components requiring high tensile strength, such as crankshafts, gears and shafts subject to stress. The material has excellent fatigue properties making it suitable for applications requiring frequent use or heavy loads.

Great Strength and Durability:

En 24 material is known for its excellent strength and durability. It contains a high level of chromium, molybdenum, and nickel, which makes it resistant to corrosion and rusting in salty water. The toughness of En 24 is mainly due to the carbon content in the material, which offers great hardness and wear resistance. This makes it perfect for marine parts such as shafts, connecting rods, and many other highly-strength applications.

High Resistance to Wear and Fatigue:

En 24 material is well suited for high-pressure marine applications requiring extreme strength and durability. It has great resistance to wear and fatigue, which means it can withstand the effects of cyclic loading and vibrations often experienced in marine environments such as propellers, drive shafts, pulleys, and winches.

Easy to Machine:

En 24 material is easy to machine, which makes it highly flexible and convenient for use in different applications. It has excellent machinability due to its composition, which allows the material to be easily cut, drilled, punched, or turned into a particular shape. This means engineering companies can work with En 24 material more efficiently, reducing costs and production time.


Despite its high strength, En 24 material is relatively affordable. En 24 is a cost-effective option without compromising its strength or durability compared to other materials that may cost more. The material’s cost-effectiveness makes it an attractive option for marine engineering professionals.

Versatility and Wide-Ranging Applications:

En 24 material is widely used in marine applications such as engine components, propeller shafts, marine installations, boat building, etc. Its versatility and compatibility with various marine parts make it a popular choice for engineers and designers worldwide.


In conclusion, En 24 material is a popular choice for the marine industry due to its strength, durability, resistance to wear and fatigue, machinability, affordability, and versatility. Its unique properties make it perfect for use in various marine engineering applications. En 24 remains a sought-after material for new and existing marine projects. If you’re a marine engineer or designer looking for a material that offers high strength, durability, and excellent machinability, En 24 material is a perfect option.
