What is EN41 Nitriding Steel?

EN41, also known by designations like 41CrAlMo7 or 1.8509, is a low-alloy steel specifically formulated for the nitriding process. The inclusion of aluminum, chromium, and molybdenum allows the steel to form extremely hard metallic nitrides on its surface when exposed to a nitrogen-rich environment at high temperatures. This case-hardening process imparts a surface hardness that can reach up to 68 HRC, providing exceptional resistance to wear, abrasion, and seizure.

Unlike conventional case-hardening steels, EN41 achieves this surface hardness with minimal distortion, as the nitriding process occurs at lower temperatures than carburizing or induction hardening. This dimensional stability is critical for precision-engineered components that require tight tolerances. Underneath the hard case, the core of EN41 steel retains its toughness and strength, offering excellent resistance to shock loads and fatigue. This dual-property profile—a hard surface with a resilient core—makes EN41 an ideal choice for components subjected to high stress and friction.

Nifty Alloys LLC supplies EN41 in various conditions, including normalized or hardened and tempered, to suit your specific machining and manufacturing processes.

Key Properties & Features

EN41 Nitriding Steel offers a unique set of properties that make it suitable for some of the most demanding engineering applications.

• Exceptional Surface Hardness: Achieves a surface hardness of up to 68 HRC (or over 900 HV) after nitriding, creating a highly durable case.
• Excellent Wear and Abrasion Resistance: The hard nitrided surface provides superior resistance to friction, galling, and abrasive wear.
• Tough and Ductile Core: The core of the material remains tough and resilient, capable of absorbing shock and impact loads without fracturing.
• High Fatigue Strength: The combination of a hard case and a tough core enhances the material's resistance to fatigue failure under cyclic loading.
• Superior Dimensional Stability: Nitriding is a low-temperature process, which minimizes distortion and allows for the production of high-precision components.
• Good Strength at Elevated Temperatures: EN41 retains its hardness and strength at operating temperatures up to 500°C.
• Magnetic Properties: The steel is magnetic in all conditions.
