What is EN40B Steel (722M24) ?

EN40B is a high-tensile alloy steel specifically engineered for nitriding. This thermochemical process diffuses nitrogen into the surface of the steel, creating a case-hardened layer without the need for quenching. The result is a component with an extremely hard, wear-resistant surface and a tough, ductile core.

This unique combination of properties makes EN40B steel indispensable for parts subjected to heavy loading, friction, and fatigue. Its formulation provides an excellent response to the nitriding process, ensuring a consistent and deep case hardness. Furthermore, the material maintains exceptional dimensional stability throughout the heat treatment cycle, a critical factor for manufacturing high-precision components where tight tolerances are non-negotiable. At Nifty Alloys LLC, we supply EN40B steel that delivers these performance characteristics with proven reliability.

Key Properties & Features

EN40B (722M24) alloy steel offers a distinct set of advantages for engineering applications where durability and precision are paramount. Its features are tailored for components that must perform under extreme mechanical stress.

• High Surface Hardness After Nitriding: The material is designed to achieve a very hard surface case (over 65 HRC) through nitriding, providing exceptional resistance to wear, abrasion, and seizure.
• Excellent Core Strength and Fatigue Resistance: Beyond its surface hardness, EN40B maintains a strong and tough core, enabling it to withstand high cyclical loads and resist fatigue failure.
• Toughness and Wear Resistance Under Heavy Load: The combination of a hard surface and a ductile core makes it suitable for components that experience both high friction and significant impact forces.
• Good Machinability Before Hardening: In its annealed or normalized state, EN40B can be readily machined, allowing for the creation of complex geometries before the final hardening process.
• Retains Stability and Accuracy Post-Heat Treatment: The low-temperature nitriding process minimizes distortion, ensuring that precision-machined parts retain their dimensional accuracy.
• Suitable for Precision Parts and High-Stress Components: These properties make EN40B the material of choice for critical parts where performance and reliability cannot be compromised.
