When it comes to Carbon Steel EN-1A Bars, these low-carbon free-cutting steels typically feature a chemical composition that includes carbon (0.07–0.15%), manganese (0.90–1.30%), and sulfur (0.20–0.30%), along with trace amounts of phosphorus. While they aren’t heat-treatable, their high sulfur content gives them exceptional machinability. The mechanical properties boast a tensile strength ranging from 370 to 460 MPa and a yield strength of about 280 MPa. Although they aren’t ideal for welding or forming, EN-1A bars shine with their excellent surface finish and dimensional accuracy, making them a go-to choice for high-speed machining in automated production settings.
