EN 10083-2 C40E is a medium carbon non-alloy steel grade designed for applications requiring higher strength, good toughness, and reliable performance with improved chemical quality. With a nominal carbon content of around 0.40% and controlled phosphorus and sulphur levels (E quality), C40E steel offers more consistent mechanical properties and better reliability than standard C40 grades. Supplied in bar form, EN 10083-2 C40E steel is widely used in mechanical engineering and industrial manufacturing applications. This grade is manufactured in accordance with EN 10083-2, which specifies technical delivery conditions for quenched and tempered steels. Ladhani Metal Corporation is a reliable manufacturer, supplier, and exporter of EN 10083-2 C40E steel bars. Our materials are sourced from approved mills and supplied with controlled chemical composition, consistent mechanical properties, and precise dimensional accuracy as per EN 10083-2 requirements. Forms of Supply (as per grade): Black round bar, bright round bar, peeled bar, hex bar, square bar, flat bar, forged bar Explanation of Designation (C40E): • C – Carbon steel • 40 – Approx. 0.40% carbon content • E – Special quality steel with controlled phosphorus and sulphur content Chemical Composition (% – typical limits): • Carbon (C): 0.37 – 0.44 • Manganese (Mn): 0.60 – 0.90 • Silicon (Si): ≤ 0.40 • Phosphorus (P): ≤ 0.025 • Sulphur (S): ≤ 0.025 Mechanical Properties (Typical, normalized / quenched & tempered): • Tensile Strength: 600 – 750 MPa • Yield Strength: ≥ 350 MPa • Elongation: ≥ 14% • Hardness: 180 – 220 HB (can be increased by heat treatment) Key Features: • Medium carbon steel with improved quality consistency • Higher strength and hardness than C35 grades • Excellent response to quenching and tempering • Good machinability in normalized condition • Suitable for precision and load-bearing components Material Characteristics: EN 10083-2 C40E steel bar provides a strong combination of strength, toughness, and wear resistance with enhanced purity levels. Its medium carbon content allows effective heat treatment to achieve increased hardness and tensile strength, making it suitable for mechanically stressed and precision-engineered components. Applications: • Shafts, axles, and crankshafts • Gears, pins, and keys • High-strength bolts and studs • Forged and machined components • Automotive and general engineering parts Conclusion: Ladhani Metal Corporation supplies high-quality EN 10083-2 C40E steel bars in various industrial bar forms with consistent quality and dependable performance. With controlled chemistry, excellent heat-treatability, and wide industrial usability, C40E steel bars are a reliable choice for engineering and mechanical applications.
