EN 10083-3 30NiCrMo16-6 is a high-strength nickel-chromium-molybdenum alloy steel grade developed for applications requiring exceptional toughness, very high hardenability, and superior fatigue resistance after quenching and tempering. With a nominal carbon content of approximately 0.30% and higher nickel content compared to standard Cr-Ni-Mo grades, this steel offers outstanding impact strength and uniform mechanical properties even in heavy sections. 30NiCrMo16-6 is widely used in critical engineering, defense, heavy machinery, and power transmission components where reliability under extreme loading conditions is essential. The material is produced 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 30NiCrMo16-6 alloy steel plates and bars, supplied with certified mill test certificates and strict quality control. Forms of Supply (as per grade): Hot rolled plates, normalized plates, quenched and tempered plates, flame cut 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 (30NiCrMo16-6): • 30 – Approx. 0.30% carbon content • Ni – Nickel for superior toughness and impact resistance • Cr – Chromium for strength and hardenability • Mo – Molybdenum for improved fatigue resistance and tempering stability • 16-6 – Indicates alloying content range as per EN standard (higher nickel content category) Chemical Composition (% – typical limits): • Carbon (C): 0.26 – 0.34 • Manganese (Mn): 0.40 – 0.70 • Silicon (Si): ≤ 0.40 • Nickel (Ni): 3.50 – 4.00 • Chromium (Cr): 1.30 – 1.70 • Molybdenum (Mo): 0.30 – 0.50 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Typical, quenched & tempered condition): • Tensile Strength: 1000 – 1200 MPa (depending on section size and heat treatment) • Yield Strength: ≥ 850 MPa • Elongation: ≥ 11% • Hardness: 300 – 360 HB • Excellent impact strength even at low temperatures Key Features: • High Ni-Cr-Mo alloy steel with exceptional toughness • Excellent hardenability for thick plates and large diameter bars • Superior fatigue and impact resistance • Good resistance to temper brittleness • Suitable for highly stressed and safety-critical components Material Characteristics: EN 10083-3 30NiCrMo16-6 alloy steel in plate and bar form provides outstanding mechanical performance in heavy sections due to its high nickel content. It ensures deep hardening capability and uniform strength distribution after heat treatment, making it ideal for critical load-bearing applications.
