EN 10084 16NiCr4 is a low alloy nickel-chromium carburizing steel grade designed for components requiring a hard, wear-resistant surface combined with a tough and high-strength core after carburizing and heat treatment. With approximately 0.16% carbon along with nickel and chromium additions, this grade offers excellent hardenability, improved core toughness, and enhanced resistance to impact and fatigue. Manufactured in accordance with EN 10084, which specifies technical delivery conditions for steels intended for carburizing treatment, 16NiCr4 steel is widely used in automotive, transmission, and general engineering industries. The nickel addition improves toughness and impact resistance, while chromium enhances wear resistance and depth of hardening, ensuring reliable mechanical performance after quenching and tempering. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10084 16NiCr4 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 (16NiCr4): • 16 – Approx. 0.16% carbon content • Ni – Nickel alloyed steel • Cr – Chromium alloyed steel • 4 – Alloy content classification Chemical Composition (% – typical limits): • Carbon (C): 0.14 – 0.19 • Manganese (Mn): 0.50 – 0.80 • Silicon (Si): ≤ 0.40 • Nickel (Ni): 0.90 – 1.20 • Chromium (Cr): 0.60 – 0.90 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Core, typical normalized condition): • Tensile Strength: 750 – 950 MPa • Yield Strength: ≥ 500 MPa • Elongation: ≥ 10% • Hardness (Core): 200 – 260 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 carburizing response • High core toughness due to nickel addition • Good hardenability from chromium content • Improved impact and fatigue resistance • Suitable for dynamically loaded components Material Characteristics: EN 10084 16NiCr4 round bars provide a strong combination of surface hardness and core toughness. The nickel addition enhances ductility and resistance to shock loading, while chromium improves wear resistance and case depth, making this grade suitable for demanding mechanical applications. Applications: • Gears and gear shafts • Transmission components • Pinions and sprockets • Automotive drivetrain parts • Heavy-duty shafts • Industrial machinery components requiring case hardening Conclusion: Ladhani Metal Corporation supplies high-quality EN 10084 16NiCr4 round bars in various diameters and finishes.
