EN-353

With a low carbon basis and alloying elements like nickel, chromium, and molybdenum that give it exceptional hardenability, wear resistance, and core toughness, EN-353 (Case Hardening Steel) is a flexible low-alloy case-hardening steel. EN-353 is perfect for gears, shafts, pinions, camshafts, and other heavy-duty automotive and engineering components because it forms a strong, wear-resistant surface with a tough, ductile core following carburizing and heat treatment. In the annealed form, it provides good strength, fatigue resistance, and machinability.

Benefits

• High Surface Hardness – Excellent wear resistance for gears, shafts, and pinions.
• Tough Ductile Core – Reduces risk of cracking or failure under heavy loads.
• Good Fatigue Strength – Ideal for cyclic and dynamic applications.
• Dimensional Stability – Maintains shape after heat treatment and during service.
• Versatile Heat Treatment – Supports carburizing, induction hardening, and nitriding.
