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. As a trusted C45 carbon steel supplier, we also provide high-grade EN41B alloy steel for advanced engineering requirements.

Key Highlights

• Excellent Surface Hardness & Wear Resistance – Achieves superior durability after nitriding, making it ideal for high-load and high-friction components.
• Toughness & Ductility – Retains strength under stress, suitable for heavy-duty operations in challenging environments.
• Versatile Applications – Used in oil & gas systems, chemical processing equipment, food industry machinery, heating systems, and water supply applications.
• Forging Range – Can be forged between 850°C to 1200°C and cooled slowly to maintain material integrity and performance.
• Nitridable Steel – Specially engineered for nitriding treatment to enhance surface hardness, wear resistance, and corrosion performance.
