EN-45 Bars from Dhruv Metals are perfect for high-stress applications, boasting excellent toughness, wear resistance, and the ability to perform well under dynamic loading conditions.
Carbon Steel EN-45 is a high-carbon spring steel, typically composed of 0.50–0.60% carbon, 0.70–1.00% manganese, along with trace amounts of silicon and chromium. This alloy is recognized for its impressive resilience, tensile strength (up to 950 MPa), and outstanding elasticity. EN-45 steel bars can be heat-treated to enhance hardness and fatigue resistance. They also offer good machinability in their annealed state while maintaining toughness after hardening. These mechanical properties make EN-45 an excellent choice for components that face repeated shocks or stresses, ensuring they perform reliably in dynamic environments.

EN-45 Bars and Rods are primarily used in automotive components like springs, shafts, and crankshafts, as well as in engineering tools and machinery parts requiring high strength and wear resistance.
EN-45 Bars and Rods offer excellent tensile strength (700-900 MPa), yield strength (450-600 MPa), and toughness, making them ideal for high-stress applications.
Carbon Steel EN-45 Bars are mainly utilized in the automotive industry for crafting leaf springs, coil springs, and suspension components, thanks to their remarkable shock absorption and flexibility. They also find applications in agricultural machinery, railway components, and industrial equipment where resistance to bending and fatigue is essential. In the defense and aerospace fields, EN-45 is used in parts that require a blend of strength, elasticity, and wear resistance. Its versatility, durability, and ability to handle cyclic loading make it a trusted material in high-stress, performance-critical settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
