Chemical composition and mechanical properties of 34CrNiMo6

34CrNiMo6 is a high-strength alloy die steel known for its exceptional mechanical properties, making it a popular choice in the production of critical engine components such as camshafts and connecting rods. However, due to its poor machinability, it is considered a challenging material to work with in manufacturing processes. The chemical composition of 34CrNiMo6 includes: - Carbon (C): 0.34% - Silicon (Si): 0.25–0.30% - Manganese (Mn): 0.5% - Molybdenum (Mo): 0.2% - Chromium (Cr): 1.5% - Nickel (Ni): 1.55% In terms of mechanical properties, after quenching and tempering, 34CrNiMo6 achieves a hardness range of 36–40 HRC. Its tensile strength (σb) reaches up to 1,100 MPa, with an elongation (δ) of 12%. The impact toughness (ακ) is approximately 8 kg/cm². Heat treatment for 34CrNiMo6 typically involves oil quenching at 850°C followed by tempering at 580°C. This process ensures the material maintains its desired balance of strength, toughness, and durability.
