EN 10084 17CrNi6-6 is a high-performance chromium-nickel alloy carburizing steel grade designed for components requiring a very hard, wear-resistant surface combined with an exceptionally tough and high-strength core after carburizing and heat treatment. With approximately 0.17% carbon along with higher chromium and nickel content, this grade offers superior hardenability, deep case hardening capability, and outstanding fatigue strength under heavy dynamic loads. Manufactured in accordance with EN 10084, which specifies technical delivery conditions for steels intended for carburizing treatment, 17CrNi6-6 steel is widely used in automotive, heavy-duty gear manufacturing, and critical engineering applications. Nickel significantly improves core toughness and impact resistance, while chromium enhances wear resistance and ensures deeper and more uniform case hardening. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10084 17CrNi6-6 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 (17CrNi6-6): • 17 – Approx. 0.17% carbon content • Cr – Chromium alloyed steel • Ni – Nickel alloyed steel • 6-6 – Alloy content classification (chromium and nickel levels) Chemical Composition (% – typical limits): • Carbon (C): 0.14 – 0.19 • Manganese (Mn): 0.50 – 0.80 • Silicon (Si): ≤ 0.40 • Chromium (Cr): 1.50 – 1.80 • Nickel (Ni): 1.40 – 1.70 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Core, typical normalized condition): • Tensile Strength: 900 – 1100 MPa • Yield Strength: ≥ 650 MPa • Elongation: ≥ 9% • Hardness (Core): 250 – 320 HB After carburizing and quenching, the surface hardness can reach approximately 58 – 62 HRC, depending on case depth and heat treatment conditions. Key Features: • Excellent deep case hardening capability • Superior hardenability due to higher chromium content • Outstanding core toughness from nickel addition • High fatigue strength and impact resistance • Suitable for heavily loaded and shock-resistant components Material Characteristics: EN 10084 17CrNi6-6 round bars provide an optimal balance of surface hardness and core strength. The higher alloy content ensures deeper case depth, improved wear resistance, and enhanced performance under cyclic and shock loading conditions, making it ideal for critical drivetrain components. Applications: • Heavy-duty gears and gear shafts • Automotive transmission components • Industrial gearbox parts • Pinions and differential components • High-load shafts • Engineering components requiring deep carburized case Conclusion: Ladhani Metal Corporation supplies high-quality EN 10084 17CrNi6-6 round bars in various diameters and finishes. With excellent hardenability, deep case hardening properties, and superior core toughness, 17CrNi6-6 steel is widely preferred for demanding automotive and industrial engineering applications.
