Dang Steel is a reputable manufacturer and supplier of **Carbon Steel EN-9 Bars** based in Da Nang, Vietnam. We take pride in delivering high-quality products that adhere to global standards. EN-9 bars are medium carbon steel bars celebrated for their outstanding wear resistance, toughness, and impressive strength, making them perfect for demanding industrial applications. At Dang Steel, we prioritize superior quality through meticulous engineering and rigorous quality control. With a strong commitment to durability, reliability, and customer satisfaction, our EN-9 bars cater to a variety of industries, including automotive, construction, machinery, and engineering, both in Vietnam and beyond.
Carbon Steel EN-9 Bars consist of **0.5–0.6% carbon, 0.5–0.8% manganese**, along with small amounts of silicon, phosphorus, and sulfur. This specific composition gives the material its hardness and toughness, making it ideal for heavy-duty applications. EN-9 steel showcases **tensile strength between 600–700 MPa**, excellent wear resistance, and moderate ductility. It can also be heat-treated to achieve higher hardness levels while still maintaining a good balance of strength and toughness. Thanks to its machinability and durability, this steel is particularly well-suited for mechanical components that face stress and impact.
