Neil Metals, located in Kolkata, India, has built a solid reputation as a reliable manufacturer and supplier of top-notch Carbon Steel EN-1A Bars. Known for their commitment to quality, Neil Metals excels in providing precision-engineered products that cater to a wide range of industrial needs. The company prioritizes quality, consistency, and customer satisfaction, ensuring that every bar meets rigorous manufacturing standards. Their EN-1A bars are highly regarded for their outstanding machinability, smooth finish, and precise dimensions. With years of expertise and state-of-the-art facilities, Neil Metals delivers dependable steel solutions to various sectors both in India and internationally, tailored to meet client specifications.
Carbon Steel EN-1A Bars primarily consist of carbon (0.07–0.15%) and manganese (0.90–1.30%), with small amounts of sulfur to enhance machinability. These bars boast a tensile strength of about 370–460 MPa and a yield strength of 230 MPa, along with an elongation of around 15%, providing moderate ductility. The Brinell Hardness falls between 121 and 140 HB. Thanks to its low carbon content, EN-1A offers excellent machinability, making it perfect for high-speed machining tasks. However, it’s not suitable for welding or heat treatment. Typically, the material is supplied in cold-drawn or bright bar form, ensuring high dimensional accuracy.

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.
Carbon Steel EN-1A Bars find extensive use in applications where high machinability and surface finish are essential. They are perfect for crafting precision components like nuts, bolts, screws, shafts, and spindles used in the automotive, general engineering, and machinery sectors. These bars are favored for mass production on CNC and automatic lathes due to their superb machining properties. Additionally, EN-1A bars are utilized in creating tools and fasteners that require intricate detailing but aren’t subjected to high stress. Their cost-effectiveness and ease of fabrication make them ideal for both small-scale and large-scale industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
