EN 10083-3 30CrNiMo8 is a high-performance chromium-nickel-molybdenum alloy steel grade designed for applications requiring very high strength, excellent toughness, and outstanding hardenability after heat treatment. With a nominal carbon content of around 0.30% and the balanced addition of chromium, nickel, and molybdenum, 30CrNiMo8 steel offers exceptional fatigue strength and impact resistance, even in large cross-section components. Supplied in plate and bar form, EN 10083-3 30CrNiMo8 alloy steel is widely used in heavy engineering, automotive, defense, and power transmission applications. This grade 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 reliable manufacturer, supplier, and exporter of EN 10083-3 30CrNiMo8 alloy steel plates and bars. Our materials are sourced from approved mills and supplied with controlled chemical composition, consistent mechanical properties, and precise dimensional accuracy as per EN 10083-3 requirements. Forms of Supply (as per grade): Hot rolled plates, normalized plates, quenched and tempered plates, cut-to-size plates, hot rolled round bars, black round bars, forged bars, peeled bars, bright round bars, square bars, flat bars Explanation of Designation (30CrNiMo8): • 30 – Approx. 0.30% carbon content • Cr – Chromium for strength, wear resistance, and hardenability • Ni – Nickel for toughness and impact strength • Mo – Molybdenum for improved hardenability, fatigue strength, and resistance to softening • 8 – Indicates alloying content range as per EN standard Chemical Composition (% – typical limits): • Carbon (C): 0.26 – 0.34 • Manganese (Mn): 0.40 – 0.70 • Silicon (Si): ≤ 0.40 • Chromium (Cr): 1.80 – 2.20 • Nickel (Ni): 1.80 – 2.20 • Molybdenum (Mo): 0.30 – 0.50 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Typical, quenched & tempered): • Tensile Strength: 900 – 1100 MPa • Yield Strength: ≥ 700 MPa • Elongation: ≥ 12% • Hardness: 260 – 320 HB (after heat treatment) Key Features: • Cr-Ni-Mo alloy steel with very high strength and toughness • Excellent hardenability for thick plates and large bar sections • Superior fatigue and impact resistance • Very good response to quenching and tempering • Suitable for highly stressed and safety-critical components Material Characteristics: EN 10083-3 30CrNiMo8 alloy steel in plate and bar form provides an exceptional combination of strength, toughness, and hardenability due to its high chromium, nickel, and molybdenum content. It achieves uniform mechanical properties across large sections, making it ideal for critical structural and dynamically loaded components. Applications: • Heavy-duty shafts, axles, and spindles • Gears, pinions, and drive components • High-strength plates for structural and fabricated parts • Automotive, defense, and aerospace components • Heavy engineering and power transmission equipment Conclusion: Ladhani Metal Corporation supplies high-quality EN 10083-3 30CrNiMo8 alloy steel plates and bars in various heat-treated and cut-to-size conditions with consistent quality and reliable performance. With very high strength, excellent toughness, and superior hardenability, 30CrNiMo8 steel is a dependable choice for the most demanding engineering and industrial applications.
