The EN-1A grade is a versatile and dependable free-cutting carbon steel, prized for its excellent machinability. Its composition is straightforward, primarily iron with controlled additions of sulphur and manganese, which gives it its distinctive ability to be shaped and threaded with ease. While it isn’t chosen for high-strength applications, its mechanical properties offer a reliable balance of adequate tensile strength and good ductility, making it exceptionally easy to work with using automated machinery, which significantly boosts production efficiency.

Carbon Steel EN-1A Bars are typically available in thicknesses ranging from 6 mm to 300 mm or more, depending on the manufacturer and specific requirements of the application.
Carbon Steel EN-1A bar has high machinability, tensile strength of 400-550 MPa, yield strength of 280 MPa, hardness of 130-180 HB, and excellent ductility for general engineering applications.
Carbon Steel EN-1A Bars are used for manufacturing precision components like gears, shafts, spindles, and fasteners due to their excellent machinability, surface finish, and suitability for high-speed machining applications.
This easy-to-machine quality makes EN-1A bars a go-to choice for a wide array of components where precision and speed of production are key. You’ll commonly find them used in the creation of bolts, studs, and nuts, as well as in various pins, shafts, and everyday non-critical fixtures. Their primary application is anywhere high-volume, automated machining is involved, allowing manufacturers to produce parts quickly with minimal tool wear, which is ideal for keeping costs down while maintaining consistent quality in mass-produced items.
