EN 10084 20MnCr5 is a low alloy manganese-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 0.20% carbon along with manganese and chromium additions, this grade offers excellent hardenability and improved core strength compared to lower carbon carburizing steels such as 16MnCr5. Manufactured in accordance with EN 10084, which specifies technical delivery conditions for steels intended for carburizing treatment, 20MnCr5 steel is widely used in automotive, transmission, and heavy engineering industries. The balanced alloy composition ensures uniform case hardening, reliable core toughness, and consistent mechanical performance after quenching and tempering. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10084 20MnCr5 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 (20MnCr5): • 20 – Approx. 0.20% carbon content • Mn – Manganese alloyed steel • Cr – Chromium alloyed steel • 5 – Alloy content classification Chemical Composition (% – typical limits): • Carbon (C): 0.17 – 0.22 • Manganese (Mn): 1.10 – 1.40 • Silicon (Si): ≤ 0.40 • Chromium (Cr): 1.00 – 1.30 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Core, typical normalized condition): • Tensile Strength: 800 – 1000 MPa • Yield Strength: ≥ 550 MPa • Elongation: ≥ 9% • 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 conditions. Key Features: • Excellent carburizing response • High hardenability due to Mn and Cr content • Strong core strength with good toughness • Uniform case depth and hardness distribution • Suitable for heavily loaded and dynamic components Material Characteristics: EN 10084 20MnCr5 round bars provide a strong combination of surface hardness and core strength. The manganese enhances hardenability, while chromium improves wear resistance and depth of hardening, making this grade ideal for high-stress mechanical applications. Applications: • Gears and gear shafts • Transmission components • Camshafts • Pinions and sprockets • Automotive drivetrain parts • Industrial machinery components requiring case hardening Conclusion: Ladhani Metal Corporation supplies high-quality EN 10084 20MnCr5 round bars in various diameters and finishes. With excellent hardenability and reliable performance after heat treatment, 20MnCr5 steel is widely used in automotive and industrial engineering applications.
