Carbon Steel EN-1A Bars are primarily made from low carbon steel with added sulfur to enhance machinability and surface finish. These bars provide moderate tensile strength, good ductility, and outstanding machining characteristics, making them ideal for high-speed automatic turning and precision components. While EN-1A steel isn’t usually heat-treated for strength, it can be case-hardened to boost surface wear resistance when necessary. Its well-balanced mechanical properties make it a great fit for applications where easy machining and fine tolerances are crucial.
