Alloy Steel EN41B / Tool Steel – Premium Nitriding Grade for High-Performance Applications

EN41B is a low-carbon alloy steel known for its exceptional wear resistance, toughness, and ductility—especially after undergoing nitriding. It’s a preferred material across various demanding industries where strength and surface hardness are critical. With excellent machinability and dimensional stability, EN41B is widely used for making high-performance components in power plants, oil & gas systems, heat exchangers, and structural applications.
