Their commitment to timely delivery and customer satisfaction has made them a go-to choice for reliable carbon steel EN-9 bar products throughout India and beyond.
Carbon Steel EN-9 Bars are primarily made up of carbon (0.36–0.44%), manganese (0.50–0.80%), along with small amounts of sulfur and phosphorus. This blend provides good tensile strength and toughness while maintaining moderate hardness. In terms of mechanical properties, EN-9 bars usually exhibit a tensile strength of 580–700 MPa, a yield strength of around 330 MPa, and an elongation of about 15–20%. These bars are recognized for their excellent machinability, wear resistance, and moderate toughness, making them perfect for components that face medium stress and impact.
