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.
