We supply Carbon Steel EN series bars, encompassing grades like EN‑1A, EN‑8, EN‑9, EN‑19, EN‑24, EN‑31, EN‑36C, EN‑44, EN‑351, and EN‑353. These bars are supplied in round, square, and hexagonal shapes and are heat-treated and precision finished to standards ASTM B446. These bars find applications in an array of engineering, automobile, and industrial machinery requirements.
These EN-grade bars have 0.1–1.2% carbon and 0.3–1.0% manganese, with some grades also having chromium, molybdenum, or nickel additions for improved hardenability
. Tensile strengths 500 to 850 MPa according to grade and heat treatment, with hardness according to temper.

They offer excellent strength, toughness, and machinability, making them ideal for a wide range of industrial applications.
They are commonly used in automotive, machinery, construction, and manufacturing for components like shafts, gears, and structural parts.
EN series bars are employed in shafts, gears, machine tool parts, crankshafts, spindles, and structural components with the need for high hardness, wear resistance, and fatigue strength. They are also applied in mining equipment components, agricultural machinery parts, and heavy-duty industrial equipment where dimensional precision and toughness are the requirements.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
