What is Carbon Steel EN-45 Series Bars ?

Carbon Steel EN-45 Bars are medium carbon steel products, containing around 0.45% to 0.50% carbon along with manganese to boost hardness and tensile strength. These bars excel in wear resistance, high tensile strength, and moderate ductility, making them perfect for high-stress and impact applications. They can be easily machined, welded, and heat-treated to achieve the desired mechanical properties. With a well-rounded mix of toughness, hardness, and strength, Carbon Steel EN-45 Bars are ideal for components that face heavy loads, repeated stress, and tough operational conditions.
