EN 10084 28Cr4 is a low alloy chromium carburizing steel grade designed for components requiring a hard, wear-resistant surface with a strong and tough core after carburizing and heat treatment. With approximately 0.28% carbon and chromium addition, this grade offers higher core strength and improved hardenability compared to lower carbon carburizing steels such as 17Cr3. Manufactured in accordance with EN 10084, which specifies technical delivery conditions for steels intended for carburizing treatment, 28Cr4 steel is widely used in automotive, heavy machinery, and general engineering industries. The chromium content enhances depth of hardening and wear resistance, ensuring consistent mechanical performance after quenching and tempering. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10084 28Cr4 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 (28Cr4): • 28 – Approx. 0.28% carbon content • Cr – Chromium alloyed steel • 4 – Chromium content range classification Chemical Composition (% – typical limits): • Carbon (C): 0.25 – 0.30 • Manganese (Mn): 0.50 – 0.80 • Silicon (Si): ≤ 0.40 • Chromium (Cr): 0.70 – 1.10 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Core, typical normalized condition): • Tensile Strength: 700 – 900 MPa • Yield Strength: ≥ 450 MPa • Elongation: ≥ 11% • Hardness (Core): 190 – 240 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 characteristics • Higher core strength due to increased carbon content • Improved hardenability from chromium addition • Good wear resistance after case hardening • Suitable for dynamically loaded components Material Characteristics: EN 10084 28Cr4 round bars provide enhanced strength and hardenability compared to lower carbon grades. The chromium content supports deeper case hardening and uniform hardness distribution, making the material suitable for medium to heavily stressed components. Applications: • Gears and gear shafts • Axles and spindles • Transmission components • Heavy-duty pins and bushings • Mechanical couplings • Industrial machinery parts requiring surface hardness Conclusion: Ladhani Metal Corporation supplies high-quality EN 10084 28Cr4 round bars in various diameters and finishes. With improved strength and hardenability, 28Cr4 steel is widely used in automotive and industrial engineering applications requiring durable, case-hardened components.
