EN 10084 10NiCr5-4 is a low carbon nickel-chromium alloy carburizing steel grade designed for components requiring a very hard, wear-resistant surface with a tough and high-strength core after carburizing and heat treatment. With approximately 0.10% carbon along with significant nickel and chromium additions, this grade provides excellent hardenability, superior core toughness, and high fatigue strength, making it suitable for heavily loaded mechanical parts. Manufactured in accordance with EN 10084, which specifies technical delivery conditions for steels intended for carburizing treatment, 10NiCr5-4 steel is widely used in automotive, heavy-duty transmission, and engineering industries. Nickel enhances core toughness and impact resistance, while chromium improves wear resistance and case hardening depth, ensuring reliable performance under dynamic loading conditions. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10084 10NiCr5-4 round bars, supplied with mill test certificates and strict quality inspection as per European standards. Forms of Supply (as per grade): Hot rolled round bars, Black round bars, Bright round bars, Peeled bars, Turned bars, Ground bars, Forged round bars Explanation of Designation (10NiCr5-4): • 10 – Approx. 0.10% carbon content • Ni – Nickel alloyed steel • Cr – Chromium alloyed steel • 5-4 – Alloy content classification (nickel and chromium levels) Chemical Composition (% – typical limits): • Carbon (C): 0.08 – 0.13 • Manganese (Mn): 0.50 – 0.80 • Silicon (Si): ≤ 0.40 • Nickel (Ni): 1.00 – 1.40 • Chromium (Cr): 0.80 – 1.10 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Core, typical normalized condition): • Tensile Strength: 800 – 1000 MPa • Yield Strength: ≥ 550 MPa • Elongation: ≥ 10% • Hardness (Core): 220 – 280 HB After carburizing and quenching, the surface hardness can reach approximately 58 – 62 HRC, depending on case depth and heat treatment parameters. Key Features: • Excellent case hardening capability • Superior core toughness due to nickel content • Good hardenability and wear resistance • High fatigue strength under dynamic loading • Suitable for heavy-duty carburized components Material Characteristics: EN 10084 10NiCr5-4 round bars offer a strong combination of deep case hardening ability and core ductility. The higher nickel content significantly improves toughness and resistance to impact, while chromium supports consistent surface hardness and wear resistance after carburizing. Applications: • Heavy-duty gears and gear shafts • Automotive transmission components • Drive shafts and pinions • Differential components • Industrial machine parts requiring high fatigue strength • Case hardened components subjected to shock loads Conclusion: Ladhani Metal Corporation supplies premium quality EN 10084 10NiCr5-4 round bars in various diameters and finishes. With excellent hardenability, strong core toughness, and reliable performance after carburizing, 10NiCr5-4 steel is widely preferred for demanding automotive and engineering applications.
