From the heart of Hamilton, New Zealand, Hemi Metals has forged a reputation as a trusted local manufacturer and supplier. We take pride in producing high-quality Carbon Steel EN-1A Bars, a fundamental material known for its reliability and ease of use. Our team is dedicated to providing not just a product, but a dependable solution for workshops and industries across the country, ensuring you have the right material to build with confidence.
The composition of EN-1A bars is straightforward, primarily consisting of carbon and manganese, which contributes to its distinctive characteristics. This material is celebrated for its excellent machinability, meaning it can be easily cut, shaped, and threaded. While it is not hardened for high-strength applications, it offers good ductility and a consistent, smooth surface finish, making it a pleasure to work with for a wide variety of projects where high tensile strength is not the primary concern.

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.
The versatility of EN-1A steel bars makes them a staple in many workshops. You’ll commonly find them used for creating studs, bolts, and general-purpose shafts where the demands are moderate. They are also ideal for light-duty gears, pins, and a host of non-critical components in machinery and assemblies. Essentially, they are the go-to choice for general engineering tasks, prototype development, and any application where easy workability is more important than extreme strength or wear resistance.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
