EN 10083-3 34CrNiMo6 is a high-strength chromium-nickel-molybdenum alloy steel grade designed for components subjected to heavy dynamic loads and high stress conditions. With a nominal carbon content of approximately 0.34% and alloying additions of chromium, nickel, and molybdenum, this grade offers excellent hardenability, superior toughness, and outstanding fatigue resistance after quenching and tempering. EN 10083-3 34CrNiMo6 alloy steel bars are widely used in automotive, heavy engineering, oil & gas, and power transmission applications. The material is manufactured in accordance with EN 10083-3, which specifies technical delivery conditions for alloy steels for quenching and tempering. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10083-3 34CrNiMo6 alloy steel bars, supplied with certified chemical composition and controlled mechanical properties to meet international standards. Forms of Supply (as per grade): Hot rolled round bars, black round bars, forged bars, peeled bars, bright round bars, square bars, flat bars Explanation of Designation (34CrNiMo6): • 34 – Approx. 0.34% carbon content • Cr – Chromium for strength, wear resistance, and hardenability • Ni – Nickel for improved toughness and impact strength • Mo – Molybdenum for enhanced hardenability, fatigue strength, and resistance to tempering softening • 6 – Indicates alloying content range as per EN standard Chemical Composition (% – typical limits): • Carbon (C): 0.30 – 0.38 • Manganese (Mn): 0.50 – 0.80 • Silicon (Si): ≤ 0.40 • Chromium (Cr): 1.30 – 1.70 • Nickel (Ni): 1.30 – 1.70 • Molybdenum (Mo): 0.15 – 0.30 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Typical, quenched & tempered condition): • Tensile Strength: 900 – 1100 MPa (can reach higher depending on section size and heat treatment) • Yield Strength: ≥ 750 MPa • Elongation: ≥ 12% • Impact Strength: Excellent toughness even at low temperatures • Hardness: 280 – 320 HB (after heat treatment) Key Features: • High-strength Cr-Ni-Mo alloy steel • Excellent hardenability for large diameter bars • Superior fatigue and impact resistance • Very good machinability in normalized or annealed condition • Reliable performance in heavy-duty and safety-critical components Material Characteristics: EN 10083-3 34CrNiMo6 alloy steel bar combines high strength with excellent toughness and fatigue resistance. Due to its strong hardenability, it maintains uniform mechanical properties across large cross sections. The presence of molybdenum improves resistance to temper brittleness and enhances high-temperature strength. Applications: • Crankshafts and camshafts • Heavy-duty shafts and axles • Gears, pinions, and couplings • Oil & gas components • Bolts, studs, and high-strength fasteners • Forged and machined mechanical parts Conclusion: Ladhani Metal Corporation supplies premium quality EN 10083-3 34CrNiMo6 alloy steel bars in various sizes and finishes to meet demanding engineering requirements. With its excellent strength, toughness, and fatigue resistance, 34CrNiMo6 is an ideal choice for critical mechanical and structural applications.
