Rupal Metals is a well-respected manufacturer and supplier located in Delhi, India, specializing in high-quality Carbon Steel EN-351 Bars designed for top-notch performance in wear-resistant and heavy-duty applications. EN-351 is a low-alloy case-hardening steel that boasts remarkable surface hardness after carburizing, along with a resilient and ductile core. At Rupal Metals, we employ cutting-edge manufacturing techniques and thorough quality checks to create EN-351 bars that excel in dimensional accuracy and material integrity. Our EN-351 bars find extensive use in the automotive, gear manufacturing, and general engineering industries, providing durability and reliability in challenging working environments.
When it comes to the composition and mechanical properties of Carbon Steel EN-351 Bars, you’ll find that it contains around 0.15–0.25% Carbon, 0.50–0.80% Manganese, and alloying elements such as Chromium (0.70–1.10%) and Nickel (1.00–1.40%). This specific blend allows the steel to undergo carburizing, resulting in a hard, wear-resistant outer layer while maintaining a tough, shock-absorbing core. After heat treatment, EN-351 can reach surface hardness levels of up to 60 HRC, with tensile strength varying from 600–850 MPa. It offers good machinability in its annealed state and excellent fatigue resistance, making it perfect for components that experience friction, load, and impact over extended service periods.
