Sahil Metals, located in Riyadh, Saudi Arabia, stands out as a top manufacturer and supplier of premium carbon steel products designed for machining and general engineering needs. Among their diverse range of offerings are the **Carbon Steel EN-1A Bars**, a type of free-cutting mild steel celebrated for its outstanding machinability, smooth surface finish, and compatibility with high-speed turning and automatic machining. These bars are extensively utilized in the production of precision components throughout Saudi Arabia and the GCC.
**Carbon Steel EN-1A Bars** (also referred to as 230M07 or AISI 1213/1215) feature a low carbon content with added sulfur (\~0.20–0.30%) to boost machinability while maintaining dimensional accuracy. While these bars aren’t designed for high-strength applications, they do provide moderate tensile strength (approximately 370–430 MPa), excellent chip-breaking properties, and a smooth finish post-machining. Available in various shapes — including round, hexagonal, and square — EN-1A bars are straightforward to machine, cut, and form.

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.
**Applications** for EN-1A Bars include the production of precision-turned components like nuts, bolts, studs, pins, bushings, and hydraulic fittings. They are particularly well-suited for automatic and CNC machines in the automotive, electrical, and general engineering industries. Although welding or heat treatment isn’t recommended due to their sulfur content, EN-1A bars excel in high-speed production settings where tight tolerances and clean finishes are essential.
