EN 10083-3 37Cr4 is a chromium alloy steel grade designed for applications requiring good strength, enhanced hardenability, and reliable wear resistance after heat treatment. With a nominal carbon content of approximately 0.37% and chromium as the primary alloying element, 37Cr4 steel provides improved mechanical properties compared to non-alloy carbon steels. 37Cr4 alloy steel bars are widely used in engineering components subjected to torsion, bending, and moderate to high dynamic loads. The material is manufactured in accordance with EN 10083-3, which specifies technical delivery conditions for alloy steels for quenching and tempering. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10083-3 37Cr4 alloy steel bars, supplied with certified mill test certificates and strict quality control to meet international standards. Forms of Supply (as per grade): Hot rolled round bars, black round bars, forged bars, peeled bars, bright round bars, square bars, flat bars Explanation of Designation (37Cr4): • 37 – Approx. 0.37% carbon content • Cr – Chromium for improved strength, wear resistance, and hardenability • 4 – Indicates chromium content range as per EN standard Chemical Composition (% – typical limits): • Carbon (C): 0.34 – 0.41 • Manganese (Mn): 0.60 – 0.90 • Silicon (Si): ≤ 0.40 • Chromium (Cr): 0.90 – 1.20 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.035 Mechanical Properties (Typical, quenched & tempered condition): • Tensile Strength: 850 – 1050 MPa • Yield Strength: ≥ 650 MPa • Elongation: ≥ 11% • Hardness: 250 – 320 HB (depending on heat treatment) Key Features: • Chromium alloy steel with good strength and toughness • Improved hardenability over plain carbon steels • Good wear and fatigue resistance • Suitable for quenching and tempering applications • Reliable performance under dynamic loading Material Characteristics: EN 10083-3 37Cr4 alloy steel bar offers a strong balance between strength and toughness. The chromium addition enhances hardenability, allowing uniform mechanical properties in medium-sized sections after heat treatment. It is suitable for components that require both surface hardness and core toughness. Applications: • Shafts and axles • Gears and transmission components • Automotive and machinery parts • Bolts, studs, and fasteners • General engineering and heat-treated mechanical components Conclusion: Ladhani Metal Corporation supplies premium quality EN 10083-3 37Cr4 alloy steel bars in various sizes and finishes to meet demanding industrial requirements. With reliable strength, good wear resistance, and excellent heat treatment response, 37Cr4 steel bars are suitable for a wide range of engineering and mechanical applications.
