EN 10083-3 39NiCrMo3 is a nickel-chromium-molybdenum alloy steel grade developed for applications requiring very high strength, excellent toughness, and superior fatigue resistance after heat treatment. With a nominal carbon content of around 0.39% and alloying elements such as nickel, chromium, and molybdenum, 39NiCrMo3 steel offers outstanding hardenability and mechanical performance, even in larger cross sections. Supplied in bar form, EN 10083-3 39NiCrMo3 alloy steel is widely used in heavy engineering, automotive, 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 39NiCrMo3 alloy steel 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 round bar, black round bar, forged bar, peeled bar, bright round bar, square bar, flat bar Explanation of Designation (39NiCrMo3): • 39 – Approx. 0.39% carbon content • Ni – Nickel for improved toughness and impact resistance • Cr – Chromium for increased strength and hardenability • Mo – Molybdenum for enhanced strength, creep resistance, and fatigue performance Chemical Composition (% – typical limits): • Carbon (C): 0.36 – 0.44 • Manganese (Mn): 0.50 – 0.80 • Silicon (Si): ≤ 0.40 • Nickel (Ni): 0.70 – 1.00 • Chromium (Cr): 0.60 – 0.90 • Molybdenum (Mo): 0.15 – 0.25 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Typical, quenched & tempered): • Tensile Strength: 900 – 1100 MPa • Yield Strength: ≥ 700 MPa • Elongation: ≥ 11% • Hardness: 260 – 320 HB (after heat treatment) Key Features: • Ni-Cr-Mo alloy steel with excellent strength and toughness • Superior hardenability for large cross sections • Excellent fatigue and impact resistance • Very good response to quenching and tempering • Suitable for heavily loaded and safety-critical components Material Characteristics: EN 10083-3 39NiCrMo3 alloy steel bar provides an excellent balance of strength, toughness, and fatigue resistance due to its nickel, chromium, and molybdenum alloying.
